Switching vss providers

I found this on technet cool info just what i need at the moment!

By Default, DPM 2010 will attempt to use a VSS Hardware provider to take snapshots of hyper-V guests located on a SAN. There may be circumstances when you might want DPM to use the in-box VSS Software provider instead of the installed VSS Hardware provider for your SAN when doing Hyper-V backups. This may be because hardware licensing has not yet been activated, or perhaps problems with the SAN (space considerations) etc. and prevents hyper-V backups from getting done.

To overcome that add the following Key on the Hyper-V host(s) you don’t want DPM to use the hadware vss provider.

[Software\Microsoft\Microsoft Data Protection Manager\Agent\UseSystemSoftwareProvider]

This should force VSS to use In-Box VSS Software provider. If at a later time, you want to revert back to using hardware VSS provider, delete the UseSystemSoftwareProvider value.
