There are several similarities between qtree SnapMirror and SnapVault. However, there are differences in how they are used.
|More suitable for providing immediate failover capability.||More suitable where data availability is less critical, and immediate failover is not required.|
|Uses the same functionality and licensing on the source and destination systems.||Uses SnapVault source system and SnapVault destination system, which provide different functionality.|
|Transfers can be scheduled at a maximum rate of once every minute.||Transfers can be scheduled at a maximum rate of once every hour.|
|Every qtree within a source volume uses one Snapshot copy each on the source system.||Only one Snapshot copy is used.|
|Snapshot copies are deleted by qtree SnapMirror when not required for replication.||Snapshot copies are retained and deleted on a specified schedule.|
|Relationships can be reversed. This allows the source to be resynchronized with changes made at the destination.||Relationships cannot be reversed. It provides the capability to transfer data from the destination to the source only to restore data. The direction of replication cannot be reversed.|
|Can be used to replicate data between systems running Data ONTAP only.||Can be used to back up both NetApp systems and open systems. However, the destination system should be a NetApp system.|
