Using Volume Group Snapshot in IBM FlashSystems

Edit online

IBM® Storage Protect Snapshot supports volume group snapshot.

IBM Storage Protect Snapshot supports backup, in-place restore, delete, and offload operations from single site and Policy-Based High Availability (HA) topologies for the IBM FlashSystem volume group snapshots.

To enable the volume group snapshot feature, see Step 7 in the Configuring Storwize family and SAN Volume Controller dynamic target allocation (SVCDTA) topic.

On IBM FlashSystem, volume group snapshots are created with the SPS_<Snapshot-ID> prefix.

Note: If you plan to use the volume group snapshot feature, consider the following key points:
  • Any existing backup taken by using the FlashCopy® mapping cannot be restored.
  • You cannot switch back to the FlashCopy mapping.
In case you want to use the FlashCopy mapping, all volume group snapshots must be deleted.
