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 

 

To perform a backup perform the following steps: 

1. 

Insert the TGBackup CD.  

2. 

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.  

3. 

Open a terminal window and logon as root user.  

4. 

Enter the command cd  /cdrom/cdrom0/TGBackup to 
change to the TGBackup directory. 

5. 

Enter the command sh  start_tgbackup to start the backup 
process; the script initiates a file system check then power the 
printer off. 

6. 

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.
