No sql. New server running only Exchange 2003 / Win 2003 & antivirus.
The PF backups seem to run ok from the networker user for exchange app, but error out when the server group starts. Backups of the filesystem, info store, and individual mailboxes work fine. I added the reccomended permissions (from the legato exchange module admin guide) and verified that they are inherited by the public store object. It is run under a separate user account just for the backup task and has no other purpose. I logged in under this same account to test it from networker user for exchange, and worked ok. If it's relavant, these folders are being replicated to/from a pre-existing 5.5 server.
Here's the relavant excerpt of the completion notice:
