Jean Marie,
I'm not sure I understand what you accomplish this way. Do you mean to
say that you would remove yesterday's snapshot and create a new one at
midnight each night? This protects you from accidents ("rm -f /data")
but not from someone who needs last Friday's version of a file.
If you need the data in the snapshot, you need to put it somewhere safe.
To summarize:
1. Unmount /data
2. Make the snapshot
3. Remount /data
4. Mount the snapshot
5. Back up the snapshot (copy the data to tape, cd, whatever)
6. Unmount the snapshot
7. Remove the snapshot
