If the snapshot is visible from the explorer (which on newer releases only happens if you set the 'cifs.show_snapshot' option), then yes, you will back up the live filesystem plus all snapshots.

The normal procedure is to create a share on a temporary snapshot you create just for the backup. Then when you backup that share you don't get the '~snapshot' in the path.

If you want to backup all the snapshots only you can create a share on the ~snapshot directory itself. In that case you will get a copy of all data in all the snapshots, although the paths will start with the snapshot name, so you'll have to be aware of that if you do a restore.

Paul Benn has a white paper on all this. Is is on line yet, Paul?

Running NT 4.0

Backup programs: Backup Exec, Arcserve IT or NT Backup

If I am backing up a F760 filer which only has one qtree with NTFS

security

and the root volume is setup for NTFS security. If I map the filer C$ from

a

NT server and backup the filer from this mapped drive where I can see the ~snapshot directory, will snapshot be backed up by the NT backup programs

I

have listed above? If so how much data will the backups contain (-ex- The active file systems plus the snapshgots)?
