Hi,

Im not sure this is the right area to post this in, but it is backup related. I have SQL server 2005, which holds close to 100 databases. We do three different types of backups in a day on these databases: 1 at 7am where we do a full backup of a specific database, 1 at 6:30pm where we do a full backup of a specific database, 1 at 8:30pm where we do all the other databases(also full backups). Our vendor that hosts our server installed shadowcopy, and that does incremental backups at 9:30pm.

Now, for some reason, our sql server backups seems ok but once shadowcopy start, it fails the vss writer(sqlserverwriter) to the point it cant connect, even though its setup as automatic restart if it fails, and i see a lot of errors during this time in the event log. There are different types of errors, but here is one of them:

2013-04-25 21:30:57.59 spid201 BackupVirtualDeviceFile::SendFileInfoBegin: failure on backup device '{ACB91C03-3021-4581-9C95-70A4A3E775AD}95'. Operating system error 995(The I/O operation has been aborted because of either a thread exit or an application request.).

our vendor thinks that our sql server backups are not closing properly(and yes our backups are marked as complete in the event log about 30 minutes before shadowcopy starts). At this point, ive tried to do a lot of research, but im at a standstill and i dont know where to look for answers regarding this issue anymore.

Has anyone else had this problem?

Next question, does their app require the "SQL Server VSS Writer" or the Windows OS flavor of the similar service called "Volume Shadow Copy"?

Last question for now.

Have you tried this Microsoft Article?

Despite the SP difference, are you using the Lightweight pooling?
