AT&T UNIX - Backing up Your Hard Disk Files

Maintaining the UNIX PC
Backing UP Your Hard DiSk Files
To maintain your system on a regular basis, you should
set up a schedule for doing backups (making floppy disk
copies of the files on your hard disk). Backing up
your system on a regular basis is a good safety
precaution against an unexpected system failure or
operator error. Although a system failure is extremely
unlikely, if one should occur you can restore your
files using the latest backup floppy disks.
The Disk BaCkup selection is available from the
Administration menu of every user name. You can use
the Disk BaCkup selection to back up all files (system
and user), only files updated since the last backup, or
a single user's files. Once the backup is complete,
the Disk Backup lets you verify the contents of each
floppy disk.
When you select the type of backup you want to perform,
a message informs you of the approximate number of
floppy disks you will need. Make sure you have enough
5 1/4-inch floppy djsks (double-sided doubJe-density
48 tracks per inch soft-sectored) that have been
formatted on the UNIX PC. For information on
formatting UNIX PC floppy disks, see "Using Floppy
Disks" in the Working with the Office section of this
manual.
Note
If you run out of formatted floppy disks
during the backup procedure, you must
stop the backup, format more floppy
disks, and then start the backup from
the beginning.
Backup Types
Backups are of three types:
o Complete backup
o Partial backup
o Back up one user
