@(#) Explains file backup policy.

> Following filesystems are automatically backed up
  daily: / /usr /usr1

> NOTE that the primary purpose of backups is to allow data recovery
  in case of disk drive failure, not to provide archival service for
  restoring files accidentally deleted or overwritten due to user error.
  
> No backup is performed on following filesystems:
    /usr/scratch
    /scratch[1-9]
