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 snapshots on the destination volume that are newer than the latest common snapshot.

  • Long-term retention is not supported with FlexGroup volumes.

    Long-term retention enables creating snapshots directly on the destination volume without requiring to store the snapshots on the source volume.

  • The snapshot command expiry-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 snapshots 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 on the source FlexGroup volume and re-create a snapshot with the same name, the next update transfer to the destination FlexGroup volume fails if the destination volume has a snapshot of the same name.

    This is because snapshots cannot be renamed for FlexGroup volumes.
