You should frequently backup all your Power Clock data files. Disaster can happen when you least expect it. The best protection is multiple backups stored at a different location. Make a habit of backing up daily and take the backup disk home.
If you're using the multi-site features of Power Clock then your data already has some backup protection built-in because each site will have a copy of the current data.
Restore Data
Power Clock must be shut down on all workstations before restoring data.
