DocuSP Emergency Recovery Utility (DSPERU)
The DocuSP Emergency Recovery (DSPERU) utility is
specifically designed for backing up and restoring DocuSP
systems. The utility allows you to restore the system files to a
hard drive that is larger or smaller than the one on which the
files were originally backed up, assuming there is enough
space on the target drive to hold the data. The utility formats
the drives without the need to install Solaris before restoring,
which saves from 30 to 75 minutes.
This section contains instructions for running the DSPERU
scripts from diskette.
The DSPERU diskette contains the following files:
•
btt
• change_log.txt
• dsp_backup_run
• dsp_dump
• dsp_restore
• dsperu_setup
• format.ans
• response.txt
• sdpart_skel.txt
DSPERU limitations
• The scripts on this diskette are still under development.
There is limited error checking. Therefore, the scripts may
display error messages or may not run as intended, if
there are unexpected differences between your system
and the systems on which the scripts were tested.
• DSPERU is designed to enable operational recovery of a
failed system. It is not intended to substitute for a
commercial backup utility or a robust Backup/Restore and
Disaster Recovery plan. Data integrity upon restoration
cannot be guaranteed.
• DSPERU does not back up external drives. Use the
Tapetool utility to back up external drive data.
• DSPERU does not give the option of partial or incremental
backups.
