Filed under: General — telnet25 @ 3:10 pm

 

Problem: VSS Backups are failing with fallowing errors. “Backup failed.Unknown Error, Error Code: 0x80042313”

  • SnapManager backup finished with the following result:Backup group set #1:,Backup SG [SG10]: Failed

Solution: I hate to say it but the solution will be rebooting the server. The reason why you are seeing the errors will be related couple things. First of all the most logical thing to do is to see Exchange Writer status to determine the state of the Exchange writer. If

High disk activity does not allow VSS to create a shadow copy in the default time period when the volumes are frozen for snapshot VSS will time out. Investigating high I/O issues and fixing them would be better approach.

Note:

A snapshot failure may leave volumes with the read-only and hidden attribute bits set. This configuration may leave volumes in an unusable state, even after you restart the computer. To see the disk signature you need to use diskpart utility from elevated command prompt (cmd.exe)

C:\>DiskPart

DISKPART> ATTRIBUTES disk

If this is yes , the attribute read ONLY!!!!

DISKPART> ATTRIBUTES disk
Read-only  : Yes
Boot Disk  : Yes
Pagefile Disk  : Yes
Hibernation File Disk  : No
Crashdump Disk  : Yes

  • Select Volume 0 ( substitute the corresponding volume in your case)
  • List Disk
  • select disk 0
attributes disk clear readonly

Try to do snapshoot after clearing the read ONLY attribute
