Advanced Open File Query using Backup Exec 12

Created: 13 Aug 2008 • Updated: 21 May 2010 | 2 comments

Hi all - Just recently started to get errors on a couple of servers (1 server has Windows Server 2003 and the other has Windows Server 2000 SP4) when doing backups over night, the message i get is that some files are being skipped, it started off as a few on each server but now it is up to 17 on 1 of them - it says that the file is in use or has the file extension.lck. Also it does complete the job but with these exceptions.


On these jobs i have selected to use Advanced File Option and chosen "Microsoft Volume Shadow Copy Service (Windows 2003 Server) and Snapshot Provider = "Automatic - Allow VSS to select the snapshot provider"  I have also checked the box to process logical volumes for backup aone at a time.


I thought by choosing AOF that the backup would still work and not skip files being used?


Does any have any idea why this is happening or any advice on how i could resolve this problem.


Thanks in advance

VSS wont be able to snap open files on a Windows 2000 Server as VSS is not present on a Windows 2000 server.  Are all of the files that are being skipped on the 2000 server?

If this response answers your concern, please mark it as a "solution"

I have a similar issue - the job is backing up a 2003 server and two Win2kSP4 servers and open file does not want to work on the Win2K servers.


It appears to be insisting on using VSS on all instances:


V-79-57344-34110 - AOFO: Initialization failure on: "C:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
VSS snapshots are not supported on the version of the operating system running on the target computer.
