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.
