I am having an IT "issue with legs", IE one that doesn't seem to want to die.
I have been trying to get two Windows Server 2012 Domain Controllers to do system state backups using the Windows Server Backup program to a network location. Though this works some of the time, it mostly doesn't. Here is some of the history on the issue.
Initially, I had both of these DCs running the system state backups to a shared network folder on a Windows 7 computer, this computer had a routine that would push this data once received over to an external hard drive for offsite storage. Doing this would work on the non PDC and sometimes on the PDC. But eventually, after a few nights of running ok, the PDC backup would fail, and all future attempts at running the scheduled backup would fail. The hung job could not be canceled via either the GUI nor command line, even though the latter would say it had been...it wasn't. The server would have to be restarted in order to get the backups to run again or to be able to interact with the scheduled backup wizard. The error was something like the network location is not available even though it was.
So I abandoned that location thinking the windows 7 20 connection limit could be the issue and re-targeted towards a NAS. Now the NAS solution always fails for both DCS, but of course in a unique way different from the previous. The initial job run will fail throwing up the following error...
"The backup operation that started at...has failed with the following error code '0x807800C5' (There was a failure in preparing the backup image of one of the volumes in the backup set)...please blah blah blah...nothing helpful etc."
When you look at the backup location, it has backed up about 8 GB of data (which as a side note is way more than the 700MB that the old server 2003 backup system states used to do)
The the following days since this first failed backup, subsequent errors are different, but consistently the following error...
"The backup operation that started at...has failed with following error code '0x8078014D' (There was a failure updating the backup for deleted items.). Please find small Jade monkey that corresponds with useless hex code or slay a dragon...etc"
Things of note, the jobs are running at 1am and 2am for each DC, I have moved the AV scans up to 3am so they don't mess with the backups. The NAS share is hidden, but has no issues writing to. Permissions are domain admins.
Thanks a lot for the help :-)
