Can't Backup - Blank Error
I could really use some help here. I'm struggling to get Acronis Backup & Recovery (v10.0.11105) working on some of our servers (Windows Server 2003). I have the client agents installed and they show up in the management console, but I can't run a backup job with them, nor can I schedule any jobs.
When I try to do a simple backup, the first thing I get is a blank error message. When I click details, I get this:
Code: 11,337,7430(0xAD000F)
Module: C:\Program Files\Acronis\BackupAndRecovery\mms.exe
Message: Error: Unhandled routine exception.
Code: 12,451(0xBE0002)
Message: Error occured while obtaining the registry value size.
In the event log of the server I'm trying to backup, I often get these errors in the Application log:
Event Type: Error
Event Source: VSS
Event Category: None
Event ID: 12292
Description:
Volume Shadow Copy Service error: Error creating the Shadow Copy Provider COM class with CLSID {79079d5c-ef20-4952-b9fc-cfd443b38641} [0x80040154].
Event Type: Error
Event Source: VSS
Event Category: None
Event ID: 20
Description:
Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {79079d5c-ef20-4952-b9fc-cfd443b38641} and Name SW_PROV is [0x80040154].
Again, this is happening on serveral (most) servers but not all of them. The account I'm using to connect and run the services is the same on all of them and it has local administrative rights to the machine. I've not had much luck with trying to get through with support so I would really apperciate some help! Thank you!
