Protecting your SnapLock volumes with SnapMirror

You can protect backups on SnapLock volumes by using the SnapMirror relationship.

If you want to protect backups on SnapLock Enterprise volumes with SnapMirror, you can use the same procedures that you use for non-SnapLock volumes.

However, if you are protecting backups on SnapLock Compliance volumes with SnapMirror, some operations, such as the snapmirror resync command, cannot be used. This is because a resynchronization operation might alter data and, by definition, compliance data must not be altered. To learn how to set up a SnapMirror relationship, see the Data ONTAP Data Protection Online Backup and Recovery Guide for 7-Mode.

In a qtree SnapMirror relationship, the resynchronization of qtree SnapMirror (using the snapmirror resync command) and resynchronization of SnapVault (using the snapvault start -r command) to SnapLock Compliance volumes is allowed. This is because Data ONTAP provides a mechanism to store the data altered by a resynchronization for subsequent retrieval.

The following table is a quick reference for which SnapLock volumes you can use the resync option on:

SnapLock Compliance destination volume  SnapLock Enterprise destination volume
Qtree SnapMirror resynchronization Yes Yes
Volume SnapMirror resynchronization No Yes
