CSBS supports one-off backup and periodic backup. A one-off backup job is manually created by users and takes effect for only one time. Periodic backup jobs are automatically driven by a user-defined backup policy.
User-defined backup name, which defaults to manualbk_xxxx
+
+
System-assigned backup name, which defaults to autobk_xxxx
+
+
+
Backup method
+
+
Full backup at the first time and incremental backup subsequently, by default.
+
CSBS allows you to use any backup (no matter it is a full or incremental one) to restore the full data of a server.

CSBS allows you to use any backup (no matter it is a full or incremental one) to restore the full data of a server.
+
+
+
Application scenario
+
+
Executed before patching or upgrading the OS or upgrading an application on an ECS. A one-off backup can be used to restore an ECS to the original state in case the patching or upgrading fails.
+
Executed before patching or upgrading the OS or upgrading an application on a server. A one-off backup can be used to restore a server to the original state in case the patching or upgrading fails.
+
+
Executed for routine maintenance of an ECS. The latest backup can be used to restore an ECS in case an unexpected failure or data loss occurs.
+
+
+
+
+
+
You can also use the two backup options together if needed. For example, associate all ECSs with a backup policy to execute periodic backup of all ECSs, and manually perform one-off backups for the most important ECSs to further ensure those ECSs' data security, as shown in Figure 1.
You can delete unwanted backups to reduce space usage and costs.
+
Context
CSBS supports manual deletion of backups and automatic deletion of expired backups. The latter deletion method is implemented using the backup retention rule in the backup policy. For details, see Creating a Backup Policy.
+
+
Prerequisites
At least one backup exists in CSBS.
The backups are in the Available or Error state.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
Click the Backups tab. Locate the ECS backup. For details, see Viewing a Backup.
In the row of the backup, click More > Delete. See Figure 1. Alternatively, select the backups you want to delete and click Delete in the upper left corner to delete them in a batch.

Editing a Backup Policy
+
This section describes how to edit a backup policy.
+
Changing the backup period does not actually change the time of the day when the backup is scheduled to run. For example, you set to run a backup job every seven days. Three days later, you modified the policy to run a backup job every five days. Then the associated server will be backed up two days after your modification.
+
To actually change when the backup is scheduled to run, dissociate the original policy and associate the server with a new backup policy.
+
+
Prerequisites
You have created at least one backup policy.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
Click the Policies tab.

+
The initial backup for an ECS is a full backup and subsequent backup operations are all incremental backups. Therefore, the initial backup takes a long time and subsequent incremental operations take shorter times. For example, a full backup of a 100 GB ECS takes approximately 30 minutes, and an incremental backup of 15 GB takes approximately 6 minutes.
+
After the instant restoration function is enabled for CSBS, it takes about several minutes to restore 100 GB data.
This section introduces how to handle a failed job.
+
Prerequisites
At least one failed job exists.
+
+
Context
After a backup job fails, a backup whose Status is Error is generated, and a message is displayed on the Backup Jobs tab page of Job Status. Click the question mark next to the message to view details.
After a restoration job fails, a message is displayed on the Restoration Jobs tab page of Job Status. Click next to the message to view details.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
Click the Backups tab and then click next to Job Status.
On the Backup Jobs tab page, view the cause of the failed job.
On the Restoration Jobs tab page, view the cause of the failed job.
Optional: Click Delete in the row of the failed job to delete the job. Alternatively, click Delete All in the upper left corner to delete all failed jobs.
When EVS disks on an ECS are faulty or ECS data is lost due to misoperations, you can use a backup to restore the ECS.
+
Context
CSBS supports backup and restoration of all EVS disks as a whole instead of part of the EVS disks on an ECS.
Data on data disks cannot be restored to system disks.
CSBS does not support restoration to ECSs that are in the Faulty, Resizing, or Verifying resizing state.
+
+
Prerequisites
EVS disks on the ECS whose data needs to be restored are running properly.
The ECS whose data needs to be restored has at least one Available backup.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
Click the Backups tab. Locate the backup for the ECS. For details, see Viewing a Backup.
In the row of the backup, click Restore. See Figure 1.
The historical data at the backup point in time will overwrite the current ECS data. The restoration cannot be undone.
+
+
Figure 1 Restoring a server
+
Optional: Deselect Start the server immediately after restoration.
If you deselect Start the server immediately after restoration, manually start the ECS after the restoration is complete.
VMs are shut down when restoring ECSs. Therefore, perform a restoration job during off-peak hours.
+
+
+
In the Specified Disk drop-down list, select the target EVS disk to which the backup will be restored.
If the ECS has only one EVS disk, the backup is restored to the only EVS disk by default.
If the ECS has multiple EVS disks, the backup will be restored to the original EVS disk. Alternatively, you can specify another EVS disk for the restoration. The specified EVS disk must have an equal capacity to or a larger capacity than the original EVS disk.
Data on data disks cannot be restored to system disks.
+
+
Click OK and confirm the restoration is successful.
In the backup list, view the restoration status. When the backup enters the Available state and no new failed restoration job exists in Task Status, the restoration is successful.

+
Do I Need to Stop the ECS Before Backing It Up?
+
No. CSBS allows you to back up ECSs that are in use. When an ECS is running, data is written onto EVS disks on the ECS, and some newly generated data is stored in the ECS memory as cached data. During a backup process, the data in the memory will not be automatically written onto EVS disks, resulting in data inconsistency between EVS disks and their backups.
+
To ensure data integrity, back up the ECS during off-peak hours when no write operation is performed on the EVS disks. Before backing up applications that requires strict consistency, such as databases and email systems, you are advised to suspend all write operations. If write operations cannot be suspended, you can stop the application systems or the ECS for offline backup.
You can manually execute a backup policy to back up an associated ECS immediately.
+
Context
If an ECS is being backed up, you cannot manually execute a backup policy on it.
If a manual backup job is still in progress, scheduled automatic backup operations will be postponed to the next backup cycle. An interval of at least 3 hours is recommended between a manual backup operation and a scheduled automatic backup operation.
+
+
Prerequisites
At least one backup policy has been created and has been associated with at least one ECS.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
Click the Policies tab.
In the upper right corner of the backup policy you want to execute, choose More > Backup Now.
Can an ECS Be Restored Using Its Backups After It Has Been Changed?
+
Yes. If an ECS has been backed up and changed such as adding, deleting, or expanding EVS disks, its backups can still be used to restore data. You are advised to back up data again after the change.
+
If you have added an EVS disk after backup, using the backup to restore data will not change the data on the EVS disk.
+
If you have deleted an EVS disk after backup, using the backup to restore data will not include the data on the EVS disk.
CSBS backs up an entire ECS. It uses the consistent backup data of multiple EVS disks to restore the service data of an ECS. CSBS ensures data security and service continuity.
+
CSBS provides crash-consistent backup of multiple EVS disks to ensure that these EVS disks are backed up at the same time. Different from application-consistent backup, crash-consistent backup does not freeze applications and file systems and does not include memory data.
A backup policy can drive the system to automatically execute CSBS backup jobs at the specified interval. Periodic backups can be used to restore data quickly against data corruption or loss.
+
Context
Automatic backup jobs require enabling the backup policy. The system automatically backs up ECSs associated with the backup policy and deletes expired backups.
Each user can create a maximum of 32 backup policies.
A maximum of 64 ECSs can be associated with a backup policy.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
On the Policies tab page, click Create Backup Policy. SeeFigure 1.
Figure 1 Creating a backup policy

+
Remarks
+
+
+
+
Name
+
+
Backup policy name.
+
It is a string of 1 to 255 characters that can contain only digits, letters, underscores (_), and hyphens (-).
+
+
backup_policy
+
+
+
Status
+
+
Whether to enable the backup policy.
+
Enabled:
Disabled:
+
+
Only after the backup policy is enabled, the system automatically backs up ECSs associated with the backup policy and deletes expired backups.
+
+
+
Execution Time
+
+
Execution time of the backup policy in a day
+
A maximum of 24 backup times can be set in a day. The backup interval must be one hour or more. If backup jobs are executed in two consecutive days, the interval between the execution times of the last backup of the former day and the first backup of the latter day must be one hour or more.
+
+
+
00:00, 02:00
+
It is recommended that backup jobs be executed during off-peak hours or when there are no services running.
+
+
+
Backup Period
+
+
Dates for executing the backup job.
+
Weekly
Specifies on which days of each week the backup job will be executed. You can select multiple days.
+
Daily
Specifies the interval (every 1 to 30 days) for executing the backup job.
+
+
+
Every day
+
If you select Daily, the first backup time is supposed to be in the day when the backup policy is created. If the creation time of the backup policy is later than the latest execution time, the initial backup will be performed in the next backup cycle.
+
It is recommended that backup jobs be executed during off-peak hours or when there are no services running.
+
+
+
Retention Rule
+
+
Rule that specifies how backups will be retained.
+
Time Period
You can choose to retain backups for one month, three months, six months, or one year, or for any desired number (1 to 99999) of days.
+
Backup Quantity
Specifies the maximum allowed number of backups for a single ECS. The value ranges from 1 to 99999.
+
You can also set long-term retention rules. Long-term retention rules can be effective together with quantity-based retention rules.
+
The value range for daily backup retention is 0 to 100.
The value range for weekly backup retention is 0 to 100.
The value range for monthly backup retention is 0 to 100.
The value range for yearly backup retention is 0 to 100.
+
For example, if you select daily backup, the system retains the latest backup every day. Although the disk is backed up for multiple times in a day, only the last backup of the current day is retained. If you set the retention number to 5, the latest five daily backups are retained. If there are more than five backup files, the system automatically deletes the earliest backups. If the daily backup, weekly backup, monthly backup, and yearly backup are all configured, the union backups are selected for retention. The long-term retention rule and the backup quantity can be executed at the same time, not generating conflicts.
+
Permanent
NOTE:
When the number of retained backups exceeds the preset value, the system automatically deletes the earliest backups. When the retention periods of retained backups exceed the preset value, the system automatically deletes all expired backups. By default, the system automatically clears data every other day. The deleted backup does not affect other backups for restoration.
This parameter applies only to backups automatically scheduled by a backup policy. Those backups generated by a manually executed backup policy are not affected by this parameter and are not automatically deleted. You can manually delete them from the backup list.
After a backup is used to create an image, the backup will not be counted as a retained backup and will not be deleted automatically.
A maximum of 10 backups are retained for failed periodic backup jobs. They are retained for one month and can be manually deleted.
+
+
+
+
6 months
+
+
+
+
+
+
More frequent backup intervals create more backups or retain backups for a longer time, protecting data with a higher level but occupying more storage space. Set an appropriate backup period as required.
+
+
Add tags to the backup.
A tag is represented in the form of a key-value pair. Tags are used to identify, classify, and search for cloud resources.
+
Tags added in a backup policy apply to all backups generated using the backup policy. These tags are used to filter and manage backup resources only. A backup policy can have a maximum of 10 tags.
Tag key. Each tag of a backup policy has a unique key. The key of a tag is user-definable or is selected from those of existing tags in TMS.
+
The naming rule of a tag key is as follows:
+
It ranges from 1 to 36 Unicode characters.
It can contain only letters, digits, hyphens (-), and underscores (_).
+
+
Key_0001
+
+
+
Value
+
+
Tag value. Tag values can be repetitive or null.
+
The naming rule of a tag value is as follows:
+
It ranges from 0 to 43 Unicode characters.
It can contain only letters, digits, hyphens (-), and underscores (_).
+
+
Value_0001
+
+
+
+
+
+
+
Click OK.
In the row of the backup policy, click Associate Server. See Figure 2.
Figure 2 Associating servers
+
In the available server list, select the ECSs you want to associate. After ECSs are selected, they are added to the list of selected servers.
A maximum of 64 ECSs can be associated with a backup policy.
If a selected ECS has been associated with another backup policy, it will be disassociated from the original backup policy automatically and then associated with the new backup policy.
If EVS disks on an ECS have been associated with a VBS backup policy, disassociate them from the VBS backup policy. Otherwise, two backups are generated for each of the EVS disks.
CSBS supports backing up ECSs with shared EVS disks.
You can only select ECSs that are in the Running or Stopped state.

CSBS
+
Cloud Server Backup Service (CSBS) enables you to back up Elastic Cloud Servers (ECSs). It works based on the consistency snapshot technology for disks. With CSBS, you can seamlessly use backup data to restore ECS data.
+
CSBS enhances data integrity and service continuity. For example, if an ECS is faulty or a misoperation causes data loss, you can use data backups to restore data quickly.
+
By default, CSBS executes a full backup for an ECS that has not been backed up, and performs incremental backups subsequently. Both full backup and incremental backup can restore an ECS to the state at the backup point in time.
+
CSBS works with ECS and OBS to back up ECS data to object storage, enhancing backup data security. Figure 1 shows the CSBS product architecture.

+
Application Scenarios
+
CSBS offers backup protection for ECSs. It supports crash-consistent backup, which enhances data security. CSBS can be used in the following scenarios:
+
Hacker attacks and virus infection
CSBS can restore an ECS to the latest backup point in time when the ECS has not been affected by hacker attacks and viruses.
+
Accidental deletion
CSBS can restore an ECS to the backup point in time prior to accidental deletion.
+
Application update errors
CSBS can restore an ECS to the backup point in time prior to application update.
+
System breakdown
CSBS can restore an ECS to the backup point in time prior to system breakdown.
CSBS can back up data of the EVS disks on an ECS, and use the backups to restore lost or corrupted data. Generated backups can be used to create images for fast restoring the service running environment.
A backup policy is a set of rules for backing up data, including the policy name, policy status, execution time of backup jobs, backup period, and retention rules. The retention rules specify the retention duration and number of retained backups. After an ECS is associated with a backup policy, it can be automatically backed up according to the backup policy.
+
+
Backup
A backup is a copy of the original data that is backed up. A backup is used to restore the original data. It can be generated in a one-off or periodic method.
+
CSBS supports one-off backup and periodic backup. A one-off backup job is manually created by users and takes effect for only one time. Periodic backup jobs are automatically driven by a user-defined backup policy.
+
The name of a one-off backup is manualbk_xxxx. It can be user- or system-defined.
The name of a periodic backup is assigned automatically by the system. The name of a periodic backup is autobk_xxxx.
+
+
Instant Restore
Instant Restore restores ECS data and creating images for backups, which is much faster than normal restoration.
+
Backups generated before Instant Restore is enabled do not support instant restoration. To use the feature, perform a full backup and select Enable next to Full Backup when creating the backup. For details, see Creating a CSBS Backup. After Instant Restore is enabled, manual backups for ECSs that have not been backed up automatically support instant restoration, without requiring the selection of Enable next to Full Backup.
+
No matter whether an ECS has been backed up or not, its automatic backups generated after Instant Restore is enabled do not support instant restoration, unless you manually perform a full backup on it.
+
+
Enhanced backup
Backups whose backup type is Common backup do not support Instant Restore. Backups whose backup type is Enhanced backup support Instant Restore.
+
+
Project
Projects are used to group and isolate OpenStack resources (computing, storage, and network resources). A project can be a department or a project team. Multiple projects can be created for one account.
Web-based service management platforms, including HTTPS-based application programming interfaces (APIs) and the management console, are provided for you to access the CSBS service.
+
APIs
Use this access method if you are required to integrate the ECSs on the cloud service platform into a third-party system for secondary development. For detailed operations, see the Cloud Server Backup Service API Reference.
+
Management console
Use this access method if you do not need secondary development. If you already have a cloud service account, log in to the management console and click Cloud Server Backup Service on the homepage.
Note the following constraints and limitations about CSBS:
+
An ECS can be associated with only one backup policy.
Shared EVS disks in ECSs can be backed up.
CSBS supports crash-consistent backup of EVS disks on an ECS but not application-consistent backup of them.
CSBS does not support consistent backup of multiple ECSs.
CSBS supports backup and restoration of all EVS disks as a whole instead of part of the EVS disks on an ECS. In addition, CSBS does not support file- or directory-level restoration.
You are not advised to back up an ECS whose capacity exceeds 4 TB.
Servers or disks at the disaster recovery (DR) site can be restored only when DR protection is disabled for servers deployed with Storage Disaster Recovery Service.
The backup you want to use to create an image meets either of the following two conditions:
The backup is in the Available state.
The backup is in the Creating state which is marked with Image can be created.
+
Once a backup creation starts, the backup enters the Creating state. After a while, a message stating "Image can be created" is displayed under Creating. In this case, the backup can be used for creating an image, even though it is still being created and cannot be used for restoration.
+
+
The backup you want to use to create an image contains the system disk data.
+
+
Description
Images created from a backup are the same, so CSBS allows you to use a backup to create only one full-ECS image that contains the whole data of the ECS's system disk and data disks, in order to save the image quota. After an image is created, you can use the image to provision multiple ECSs in a batch.
A backup with an image created cannot be deleted manually or automatically. If you want to delete such a backup, delete its image first. If a backup is automatically generated based on a backup policy and the backup has been used to create an image, the backup will not be counted as a retained backup and will not be deleted automatically.
+
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.

Auto Backup:
In the Backup Policy drop-down list, select a backup policy. Alternatively, click Create Policy to create a backup policy. For details about the parameters of a backup policy, see Creating a Backup Policy.
+
After a backup job is created, the selected ECSs are associated with the backup policy and will be periodically backed up according to the backup policy.
+
If a selected ECS has been associated with another backup policy, it will be disassociated from the original backup policy automatically and then associated with the new backup policy.
+
+
Immediate Backup:
After a backup job is created, all selected ECSs will be backed up immediately for once.

What Are the Differences Between CSBS and VBS?
+
CSBS mainly creates consistency backups online for all EVS disks of the ECS. You are advised to use CSBS in a scenario where the whole ECS, including its configurations and specifications, as well as the consistency data of multiple EVS disks, is protected, or if you want to use backups to create images and provision ECSs, in order to quickly restore the service running environment.
+
In comparison, VBS generally creates online backups for a single EVS disk (system or data disk) of the ECS. If the system disk does not have user-defined data, you can perform the backup only for the data disk using VBS to safeguard your data and reduce the backup costs.
+
CSBS backups will also be displayed on the VBS page and can be used to restore individual disks.
Inconsistent backup: During a backup, files and disks of an ECS are not backed up at the exact same time.
Crash-consistent backup: During a backup, files and disks of an ECS are backed up at the exact same point in time, while applications such as databases are not quiesced and memory data is not backed up. Therefore, application consistency is not ensured.
Application-consistent backup: During a backup, files and disks on the same ECS are backed up at the exact same point in time, and databases are quiesced and memory data is refreshed to ensure application consistency.
Yes, it can be backed up. To back up applications requiring strict consistency, such as databases and email systems, you are advised to suspend all write operations and then perform backup. If write operations cannot be suspended, you can stop the application systems or the ECS for offline backup. Without doing these, status of the ECS after restoration is similar to restart upon an unexpected power failure and log rollback will be performed on databases to keep data consistent.

+
What Are Full Backup and Incremental Backup?
+
After an initial full backup, an ECS continues to be backed up incrementally by default.
+
A full backup backs up the used capacity, that is, all data in the disk. For example, if a 100 GB disk is allocated with 40 GB data, the backup storage space occupies 40 GB, and the backup size is 40 GB.
A subsequent incremental backup backs up data changed since the last backup. If 5 GB data changed since the last backup, only the 5 GB changed data will be backed up.
+
CSBS allows you to use any backup (no matter it is a full or incremental one) to restore the whole data of an ECS. By virtue of this, manual or automatic deletion of a backup will not affect the restoration function.
+
Suppose ECS X has backups A, B, and C (in time sequence) and every backup involves data changes. If backup B is deleted, you can still use backup A or C to restore data.
+
In extreme cases, the size of a backup is the same as the disk size. The used capacity in a full backup and the changed capacity in an incremental backup are calculated based on the data block change in a disk, not by calculating the file change in the operating system. The size of a full backup cannot be evaluated based on the file capacity in the operating system, and the size of an incremental backup cannot be evaluated based on the file size change.
You can add tags to a backup as well as edit and delete these tags. These tags are used to filter and manage backup resources only.
+
Procedure
Log in to the CSBS management console.
Log in to the management console.
Click in the upper left corner of the management console and select a region and a project.
Under Storage > Cloud Server Backup Service.
+
Click the Backups tab. Locate the ECS backup. For details, see Viewing a Backup.
Click on the left of a backup name to view details about the backup.
Click Tags in the details area to expand the tag management panel.
The panel displays all tags of the backup.
+
Adding a tag
Click Add Tag in the upper left corner.
In the dialog box displayed, set the key and value of the new tag.
A tag is represented in the form of a key-value pair. Tags are used to identify, classify, and search for cloud resources. These tags are used to filter and manage backup resources only. A backup can have a maximum of 10 tags.

Tags added in a backup policy apply to all backups generated using the backup policy. These tags are used to filter and manage backup resources only. A backup policy can have a maximum of 10 tags.
Tags are used to identify and classify backups that are automatically or manually generated with CSBS. These tags are used to filter and manage backup resources only. All backups with tags are centrally managed in TMS. They can be filtered by search criteria. When a tag is added to a backup policy, the tag applies to all backups generated by the backup policy.
+
A tag is described using a key-value pair. A backup or backup policy can have a maximum of 10 tags by default. Each tag has only one key and one value. The key and value can exist in either sequence in a tag. Each key is unique among all tags of a VBS backup or backup policy, whereas values can be repetitive or blank.
Why CSBS Backups Are Also Displayed on the VBS Console?
+
To use CSBS to back up a server is to back up every disk of the server. These disk backups are also displayed on VBS Console and can be directly used to restore disks.
What Are the Differences Between Backup and Snapshot?
+
Both backup and snapshot provide data redundancy for EVS disks to improve data reliability. Table 1 lists the differences between them.

+

+
Service Recovery
+
+
+
+
Backup
+
+
Backup data is stored in OBS, instead of EVS disks. This realizes data restoration upon EVS disk data loss or corruption.
+
+
A backup is the data copy of an EVS disk at a given point in time. CSBS provides automatic backup by configuring backup policies. Deleting an EVS disk will not clear its backups.
+
+
A backup and its source EVS disk reside in the same AZ.
+
+
Data can be recovered and services can be restored by restoring the backup data to original disks or creating new disks from backups, ensuring superb data reliability.
+
+
+
Snapshot
+
+
Snapshot data is stored with EVS disk data.
+
NOTE:
Creation of and rollback to snapshots are faster than creation of and restoration from backups, because the latter requires data migration that consumes extra time.
+
+
+
A snapshot is the state of an EVS disk at a specific point in time. When you delete an EVS disk, the snapshots of the EVS disk are also deleted.
+
+
A snapshot and its source EVS disk reside in the same AZ.
+
+
Data can be recovered and services can be restored by rolling back the snapshot data to original disks or creating new disks from snapshots.
An ECS Created Using an Image Enters the Maintenance Mode After Login
+
Symptom
After you create an image using an ECS backup, use the image to create an ECS, and log in to the ECS, the ECS enters the maintenance mode and cannot be used properly.
+
+
Possible Cause
When the source ECS has data disks, the configuration parameters contained in the /etc/fstab file in the system disk of the new ECS are the source ECS's, causing the UUID information inconsistent with the new data disks. In such conditions, the ECS encounters an error when uploading /etc/fstab during the bootup and enters the maintenance mode.
+
+
Solution
This section uses CentOS as an example.
+
After creating an ECS using an image, log in to the ECS console, click Remote Login in the row of the ECS.
In the maintenance interface that is displayed, access the system as prompted.
Figure 1 Interface displayed when an ECS enters the maintenance mode
+
Run the cat /etc/fstab command to check the attachment information about the data disks.
Figure 2 Data disk UUIDs
+
Run the vi /etc/fstab command to open the file, press i to enter the editing mode, and delete the attachment information of all data disks. Then, press Esc to exit the editing mode and run :wq! to save the change and exit.
Figure 3 /etc/fstab after being updated
+
Run the reboot command to restart the system.
Figure 4 Normal bootup page
+
After entering the system, attach the data disks manually.
Figure 5 Attaching the data disks manually
+
Run the blkid command to obtain the UUID information of the data disks.
Figure 6 Obtaining UUIDs of data disks
+
Run the vi /etc/fstab command to open the file, press i to enter the editing mode, and add the attachment information of all data disks. Then, press Esc to exit the editing mode and run :wq! to save the change and exit.
Figure 7 Adding attachment information of data disks
+
After the information is added, the system will automatically attach the data disks on restart.
Quotas can limit the number or amount of resources available to users, such as the maximum number of ECSs or EVS disks that can be created.
+
If the existing resource quota cannot meet your service requirements, you can apply for a higher quota.
+
+
How Do I View My Quotas?
Log in to the management console.
Click in the upper left corner and select the desired region and project.
In the upper right corner of the page, click .
The Service Quota page is displayed.
+
View the used and total quota of each type of resources on the displayed page.
If a quota cannot meet service requirements, apply for a higher quota.
+
+
+
How Do I Apply for a Higher Quota?
The system does not support online quota adjustment. If you need to adjust a quota, call the hotline or send an email to the customer service mailbox. Customer service personnel will timely process your request for quota adjustment and inform you of the real-time progress by making a call or sending an email.
+
Before dialing the hotline number or sending an email, make sure that the following information has been obtained:
+
Domain name, project name, and project ID, which can be obtained by performing the following operations:
Log in to the management console using the cloud account, click the username in the upper right corner, select My Credentials from the drop-down list, and obtain the domain name, project name, and project ID on the My Credentials page.
A region and availability zone (AZ) identify the location of a data center. You can create resources in a specific region and AZ.
+
A region is a physical data center, which is completely isolated to improve fault tolerance and stability. The region that is selected during resource creation cannot be changed after the resource is created.
An AZ is a physical location where resources use independent power supplies and networks. A region contains one or more AZs that are physically isolated but interconnected through internal networks. Because AZs are isolated from each other, any fault that occurs in one AZ will not affect others.
+
Figure 1 shows the relationship between regions and AZs.
+
Figure 1 Regions and AZs
+
+
Selecting a Region
Select a region closest to your target users for lower network latency and quick access.
+
+
Selecting an AZ
When deploying resources, consider your applications' requirements on disaster recovery (DR) and network latency.
+
For high DR capability, deploy resources in different AZs within the same region.
For lower network latency, deploy resources in the same AZ.
+
+
Regions and Endpoints
Before you use an API to call resources, specify its region and endpoint. For more details, see Regions and Endpoints.
