Restoring a volume from an instant space-optimized snapshot

It may sometimes be desirable to reinstate the contents of a volume from a backup or modified replica in a snapshot volume. The following command may be used to restore one or more volumes from the specified snapshots:

# vxsnap [-g diskgroup] restore volume|volume_set \
  source=snapvolume|snapvolume_set \
  [[volume2|volume_set2 \
  source=snapvolume2|snapvolume_set2]...]\
 [syncing=yes|no] 

For a space-optimized instant snapshot, the cached data is used to recreate the contents of the specified volume. The space-optimized instant snapshot remains unchanged by the restore operation.

Warning:

For this operation to succeed, the volume that is being restored and the snapshot volume must not be open to any application. For example, any file systems that are configured on either volume must first be unmounted.

It is not possible to restore a volume from an unrelated volume.

The following example demonstrates how to restore the volume, myvol, from the space-optimized snapshot, snap3myvol.

# vxsnap -g mydg restore myvol source=snap3myvol
