Select a specific VSS Provider

Aug 27, 2012 at 1:28 PM


I've noticed that many writers (for example the SQL Server writer) have problems to create a snaphshot when another provider than the "Microsoft Shadow Copy Provider" is found on the machine (for example the Acronis provider).

VSS uses providers in following order: Software provider, Hardware provider and at last System provider (like the Microsoft Provider). Because of this, any other provider will be chosen before the Microsoft provider, causing the problems.

A workaround would be to remove the entries of the other providers from the registry and restart the VSS Service. After the snapshot the registry must be restored and the VSS service restarted again. But it's obvious this isn't a clean solution...

Has anyone a solution how to specify a certain provider when creating a snapshot?
