The Pure Storage FlashArray Replication feature creates a replica copy of the primary snap copy of the local array on a remote array.
When you run a snap backup operation, the snapshot is created on the local array and on the remote array.
Key Features
-
The key feature of the Pure Storage FlashArray Replication feature is that the primary copy and the replica copy are independent of each other and can have separate retention policies.
-
The replication job runs inline with the snap backup and status of the snap job on the primary snap copy is set to Complete only after the replication to the target array completes. This prevents accidental deletion of snaps on source array before replication to the target array completes.
Considerations
The limitations of the Pure Storage FlashArray Replication feature are as follows:
-
The revert operation is not supported on the replica copy.
-
For the Microsoft Hyper-V agent, the snapshots replicated on the target array are crash-consistent, and the primary snapshots are application consistent.
-
For inline replication, replication is performed only if the subclient on which you run the snapshot operation is associated with the replica copy.
-
Active DR feature is not supported.
