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.
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.
