System Backup

1. If doing a backup for the first time, set a password for the user id backup by selecting Change a users password from the Account Administration page.

2. Make sure the tape is write enabled. For a tape to be write enabled the sliding window on the edge of the tape must be closed.

3. Insert the tape into the drive and wait for the drive lights to stop blinking.

4. Log in using the user id backup and the password chosen above. This will start the backup process.

   Note: you must be sitting at the console of the server to log in as backup. Logins over the network will be refused.

5. The status of the backup will be displayed as the backup progresses (this may take a while).

6. When finished, the tape will be automatically ejected from the drive and you should see something similar to the following to signify the backup was successfull.

   Finished backup.  Unmounting tape.
   
   Backup ended successfully.
