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. To verify and record snapshot availability on the remote array, you must run the auxiliary copy operation. For more information, see Copying Snapshot Metadata to the Replica Copy and Verifying Snapshot on 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.
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.
