Everything has been working great with our Backup until three nights ago. Our full backup ran without a problem, but the next day (differential backups), I suddenly start getting the following error on all of our Exchange 2007 storage groups:
V-79-57344-65055 - AOFO: Initialization failure on: "\\[servername]\Microsoft Information Store\Default Storage Group". Advanced Open File Option used: No.
Snapshot provider error (0xE000FE1F): The device cannot be found.
Same error on all three storage groups and they no longer show up when creating selection lists in BE.
Nothing was changed on that server between the the two backups, so I'm pretty confused as to why the storage groups would suddenly be invisible to BE. I've restarted both the Exchange and BE services and checked the logs for anything that might hint at the problem. No luck. Exchange itself seems to be running perfectly normal.
Any help would be greatly appreciated:
Server 1 - Mail Server: Exchange 2007 SP1 on Server 2003 R2 x64
Server 2 - Management: Backup Exec 12.5 on Server 2003 R2 x86 (Also a GC server)
Server 3 - File Server: Server 2008 R2 x64 (Primary DC/DNS, etc.)
