In http://www.groove.net/support/forums/messageview.cfm?catid=17&threadid=9497&STARTPAGE=1 alcad asked about how a single user might back up their account and spaces.

This is a benefit of using our service. By uploading your account(s) to PopG and then fetching any spaces these will automatically be backed up a) because accounts and spaces will co-exist on your computer and as part of our service and b) because we backup all data every night.

And bear in mind that just one account from PopG could be used for several Groove accounts, thereby backing up your whole companies data for just one PopG account!
