Constraints and Limitations

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.
