TGBackup

TGBackup is an interim tape backup tool that supplements the

DocuSP System Backup utility. Backing up to tape in not yet

available in the Backup and Restore feature in DocuSP.

TGBackup provides the ability to backup the system files to a tape.

TGBackup is only available on a Sun SPARC workstation.

TGBackup is installed on the DocuSP controller by the Xerox

service representative. The TGBackup utility consists of the

following files:

♦ TGBackup.htm – these directions in html format.

♦ start_tgbackup – the TGBackup launch script

♦ run_tgbackup – the script used to invoke backup on a reboot of

the DocuSP

♦ tgbackup – the backup utility

♦ tg_checkswap – a script to check for and recreate the swap

space

♦ start_tgrestore – the recovery launch script

♦ tgrestore – the recovery utility

Performing a backup

To perform a backup perform the following steps:

Insert the TGBackup CD.

Ensure the tape drive is connected and powered on. Insert a

blank write-enabled tape cassette. If multiple tape drives are

on the system, make sure that only the drive you wish to use is

ready or online. TGBackup will use the first ready tape drive it

finds.

Open a terminal window and logon as root user.

Enter the command cd /cdrom/cdrom0/TGBackup to

change to the TGBackup directory.

Enter the command sh start_tgbackup to start the backup

process; the script initiates a file system check then power the

printer off.

Power the printer back on. TGBackup interrupts the boot

process, locates the tape drive and starts the backup to tape.

Once every ten minutes the screen updates with the

percentage of the job completed and an estimate of how much

more time is required to finish dumping the current file system.

A typical system being dumped to 4mm tape takes an average

of 2 hours.
