Commvault extends the management of snapshots with PowerScale to include the ability to perform offline replication of snapshots. With this method, you can copy snapshots from one PowerScale cluster to another using the SyncIQ replication software module available in OneFS. Within Commvault, different retention rules can be applied to the replica/target snapshot and to the primary/source snapshot, and the replica snapshot can be used for restoring operations as well. This approach takes advantage of the many benefits of SyncIQ. Those benefits include sending only changed data (blocks), parallelized data transfer using as many or as few nodes as wanted on the source and target clusters, impact throttling, and bandwidth metering, with the single pane management available with Commvault.
For configuration details, see the Offline replication of snapshots: PowerScale SyncIQ section in
Appendix: Integrations: Configuration steps.
