Exchange 2007 Backup Issue
Could do with some help with an issue I've been trying to solve for a few weeks now.
We're getting this error when trying to backup our Exchange 2007 error -
Backup- 'ServerName'V-79-57344-34070 - AOFO: Initialization failure on: "\\Server_Name\Microsoft Information Store\First Storage Group". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot provider error (0xE0008516): Resources specified for snapshot do not have any valid data on them. Check if files were deleted or renamed.
Check the Windows Event Viewer for details.
If I uninstall the BackupExec Agent software from the Exchange server and re-push it from the Backup server the backup will work once and then fail again with above error when re-run.
'Vssadmin list writers' shows to 'Microsoft Exchange Writers' both of which are stable with 'No errors'. On occiasion though the first has displayed 're-tryable error' but even then the backup has worked once.
Does anyone have any idea? Or even why the re-installation of the agent fixes the backup initially? I have not been restarting the server at the same time.
Any pointers would be appreciated.
