Minimum Backup Rights or Alternative Solution

Hi All,

We are currently running Backup Exec 2010 R3 and we are looking for a work around for the rights needed to perform backups.  We have a maintanence account set up to perfrom all of our backups that's currently in the Domains Admin group.  I understand that Symantec needs the backup account to have Domain Admin rights, but we have been forced to remove the account out of that group due to policy changes.  Do we have any options other than adding the account to the local administrators group on each server to perform the backups?  Symantec's solution seems to only be adding the account responsible for backups to the Domain Admins account.  Any suggestions would be greatly appreciated.
