Permissions required for the local SYSTEM account to run DISASTER_RECOVERY backup

Ahoy mates,

We have a strange problem with one of our servers here, being backed up with Networker 7.6.3. It all goes fine except for the DISASTER_RECOVERY set, which fails every time. I won't bore you with the details, error messages etc., but basically after a lot of troubleshooting I've found that the only way to get this to work is to have the Networker service run as another account, for example my domain account, works fine.

Therefore it seems like the local SYSTEM account is running into some problems when trying to do the whole VSS, disaster_recovery, business.

I've asked EMC to provide me with specific details on what and where the permissions are required, so that I can go through and check it all, but so far they haven't come up with anything.

I'm hoping that someone in here might be more helpful?

Thanks!

Oh I should mention that it's a Windows Server 2008 32-bit client.
