SnapMirror technical details

There are some convenient features you should be familiar with before creating a SnapMirror data protection relationship. You also need to be aware of compatible ONTAP versions for SnapMirror relationships and basic SnapMirror limitations.

Using path name pattern matching
You can use pattern matching to specify the source and destination paths in snapmirror commands.
Using extended queries to act on many SnapMirror relationships
You can use extended queries to perform SnapMirror operations on many SnapMirror relationships at one time. For example, you might have multiple uninitialized SnapMirror relationships that you want to initialize using one command.
Ensuring a common Snapshot copy in a mirror-vault deployment
You can use the snapmirror snapshot-owner create command to preserve a labeled Snapshot copy on the secondary in a mirror-vault deployment. Doing so ensures that a common Snapshot copy exists for the update of the vault relationship.
Compatible ONTAP versions for SnapMirror relationships
You should verify that the source and destination volumes are running compatible ONTAP versions before creating a SnapMirror data protection relationship.
SnapMirror limitations
You should be aware of basic SnapMirror limitations before creating a data protection relationship.
