Considerations for creating a SnapVault backup relationship and a unified data protection relationship for FlexGroup volumes
You must be aware of the considerations for creating a SnapVault backup relationship and unified data protection relationship for FlexGroup volumes.
-
You can resynchronize a SnapVault backup relationship and a unified data protection relationship by using the
-preserve
option that enables you to preserve Snapshot copies on the destination volume that are newer than the latest common Snapshot copy. -
Long-term retention is not supported with FlexGroup volumes.
Long-term retention enables creating Snapshot copies directly on the destination volume without requiring to store the Snapshot copies on the source volume.
-
The
snapshot
commandexpiry-time
option is not supported for FlexGroup volumes. -
Storage efficiency cannot be configured on the destination FlexGroup volume of a SnapVault backup relationship and unified data protection relationship.
-
You cannot rename Snapshot copies of a SnapVault backup relationship and unified data protection relationship for FlexGroup volumes.
-
A FlexGroup volume can be the source volume of only one backup relationship or restore relationship.
A FlexGroup volume cannot be the source of two SnapVault relationships, two restore relationships, or a SnapVault backup relationship and a restore relationship.
-
If you delete a Snapshot copy on the source FlexGroup volume and re-create a Snapshot copy with the same name, the next update transfer to the destination FlexGroup volume fails if the destination volume has a Snapshot copy of the same name.
This is because Snapshot copies cannot be renamed for FlexGroup volumes.
