Backup - Cleanup Symantec Backup Exec 10d History
Date: 11 Jan 2008
This script is very much one to be used with care, and only in specific circumstances.
I inherited an enterprise backup solution that used Symantec Backup Exec 10d to backup SQL databases across a 100Mb link to a remote disk array. It performed like a trained tabby cat (ie 'as and when it pleased') and it was a nightmare even to perform simple tasks such as opening a window.
Weeks of hair tearing frustration finally uncovered the problem - the backup software had never had its history archived. This resulted in 5 years of DB and log backup history for over 50 servers being maipulated each time the management console was manipulated.
I located the archiving function, but this was unable to cope with the volume of data in a timely manner over the slow (ie overloaded) WAN.
Plan B was the only plan left and it was a risky one - to perform the archiving manually and directly on the Symanted Backup Exec database. After some extensive and careful investigation and testing, I produced the script below. This successfully deleted several GB of data from the history tables and resurrected the software into something usable and reliable.
It is likely that the underlying DB structure hasn't changed much over the years, so the script may still work.
However, please USE WITH CARE.
