If you are using the tar command to back up the snapshot, mount the snapshot before backing it up.
Become superuser or assume an equivalent role.
Create a mount point for the snapshot.
For example:
# mkdir /backups/home.bkup |
Mount the snapshot.
# mount -F ufs -o ro /dev/fssnap/1 /backups/home.bkup |
Change to the mounted snapshot directory.
# cd /backups/home.bkup |
Back up the snapshot with the tar command.
# tar cvf /dev/rmt/0 . |
