  Table 2 Parameter description

  Parameter	Type	Description
  backup_policy	Object	Backup policy information. For details, see Table 3.

  Table 3 backup_policy field data structure description

  Parameter	Type	Description
  keep_days	Integer	Full backup retention days. Value: 1 to 732 Minimum value: 1 Maximum value: 732
  start_time	String	Full backup time window. The creation of an automated backup will be triggered during the backup time window. The value must be a valid value in the "hh:mm-HH:MM" format. The current time is in the UTC format. The HH value must be 1 greater than the hh value. The values of mm and MM must be the same and must be set to 00.
  period	String	Full backup period. Data will be automatically backed up on the selected days every week. The value is a number separated by commas (,), indicating the days of the week.
  differential_period	Integer	Differential backup period. An automated differential backup will be performed on the specified minutes.
  rate_limit	Integer	Upload speed at which data is uploaded to OBS. 0 MB/s indicates that the speed is not limited. The upload speed is related to the bandwidth.
  prefetch_block	Integer	Number of prefetch pages from the modified pages in the disk table file during a differential backup. When modified pages are adjacent (for example, with a bulk data load), you can set this parameter to a large value. When modified pages are scattered (for example, random update), you can set this parameter to a small value. The default value is 64.
  file_split_size	Integer	Size by which full and differential backup files are split, in GB. The value is from 0 to 1024, but it must be a multiple of 4. The default value is 4. 0 indicates the size is not limited.
  enable_standby_backup	Boolean	Whether to enable backup on a standby node. Value: true or false
  table_list	Array	Table-level backup information. For details, see Table 4.

  Table 4 table_list field data structure description

  schema_name	String	Schema name.
  table_name	String	Table name.
