Backup and Restore

2-10

System Guide

If the files and directory listed above are present, the 
installation was successful.

The following information and equipment are required prior to 
starting the backup.
•

The root password

•

A tape drive connected and powered on with a blank tape 
inserted. Ensure the tape is write-enabled (write-protect 
tab in the closed position).

NOTE: The backup overwrites the tape cartridge that is 
inserted. Ensure that no valuable data is present on the tape 
if it is not blank. The tape is overwritten with no warning.

NOTE: The system is rebooted during the backup process. 
Ensure that the system is not actively receiving jobs before 
starting the backup. It is recommended that you set all 
queues to [Accept = No] and [Release = No] in the Queue 
Manager prior to initiating a backup.

1. Ensure a blank tape cartridge has been inserted into the 

tape drive.

2. Open a terminal window and logon as root.
3. From the /export/home/xrxusr directory, enter ls to list 

all files. Verify that the file btt is listed. If it is not, repeat 
the DSPERU installation procedure described in the 
previous section.

4. Enter sh btt to initiate the backup. The system reboots 

and starts the backup.

If the system returns the message btt: not found, verify that 
you are in the right directory by entering pwd to verify your 
location. If you are in a different directory, enter the following 
command to change to the correct one. 
cd  /export/home/xrxusr
The system generates a message approximately every 10 
minutes during the backup with an estimate of how long it will 
take to complete the backup from that point. 
NOTE: If all the data cannot be stored on one cassette, the 
system pauses when it detects that the tape is full, and 
displays messages similar to the following:

DUMP: End-of-tape detected
