Backup Exec 2012 v14.0 Rev 1798 (64Bit)
Problem: I used live update to install the 201596 hotfix on my CAS last week. The update showed successful, but after the reboot there were problems. The following three services were set to disabled after the reboot, Backup Exec Deduplication Engine, Backup Exec Deduplication Manager and PostgreSQL Server 8.3. Also, all disk storage was missing (Local Backup to Disk Storage, Local Deduplication Storage and Network Disk Storage). Only tape storage remained.
Troubleshooting: I tried to add a disk storage location back and re-catalog the sets, but that operation failed with a duplicate key error. I deleted that disk storage and then was unable to see it as a storage location choice to add again.
I uninstalled the hotfix through the windows 2008 R2 uninstall utility. The storage was still gone. I reapplied and the hotfix with no change. Those three services were automatically set to disabled on each uninstall and install of the hotfix.
Resolution: I uninstalled the hotfix and recovered the sql database to the last backup before the 201596 hotfix. All of my storage returned. I can only conclude that the hotfix deleted my disk storage information from the database.
Some server agents acted strangely, but I've since been able to resolve those issues.
I'm sorry that it took me a week to post this, but this 2012 version depresses me. I used to do more than deal with backups before BE2012. I didn't see anyone else post about this kind of thing happening for this hotfix, so maybe it doesn't matter.
