BE2012 SQL Full then Inc backup, Inc backup does not run
I have a MS Server 2008, SQL 2012 server I've been backing up for a while now. Basically, I configured a Full backup job to run nightly followed directly by an Incremental job to fullfill the Logs backup requirement. These backups go to a virtual tape library then get dumped to tape automatically after an eject of the virtural tape occurs. So, I set the Inc job to eject the tape. The requirement here being I need a nightly full backup to disk, then tape. Problem is... Just the other day, the Incremental job just won't run anymore, no error, doesn't even show up in the log even though it's clearly scheduled. Is there some unstated rule in BE2012 that it doesn't run a second Incremental stage if a Full backup occurs? I'd expect an error or a skipped job message to at least indicate what happened. It's just odd. Like I said, it WAS working then just quit last week. I even deleted the old job and created a new to see if that was the issue with no luck. Anyone have any ideas?
