Restore SnapVX snapshot
Use the symsnapvx restore command to restore a snapshot's point-in-time data back to the original source device. SnapVX restore operations are inherently differential, so only the changed tracks are copied back to the source device. An expired secure or regular snapshot cannot be restored.
NOTE: A restore session must be terminated before terminating the original snapshot session.
Options
- -preaction <ScriptFile>
- Executes the specified script before a snapshot is restored.
- -postaction <ScriptFile>
- Executes the specified script after a snapshot is restored.
- -remote
- Specifies data will be copied to the remote mirror of the RDF device. Not allowed on nocopy linked target.
- -snapid <snapsetID>
- Executes a restore using the snapsetID instead of relative generation generation number.
Examples
To restore generation 5 of the 6:00 AM snapshot, enter:
symsnapvx -sid 001 -sg StorageGroup1 -snapshot_name 600am -gen 5 restore
If a source device is added to a storage group, the added device is missing snapshots that were created before the new device was added. If a restore is requested for a snapshot that is missing for a newly added device, this new device is made Not Ready, and the application should not be using this device. SnapVX behavior when adding source devices provides additional details.
