I can't install cygwin or a daemon for that matter on the Windows Server, but I could execute a scheduled job to run a Widows port of rsync on the file server which I am not opposed to at all. My only problem with that is how do I then trigger the Bacula server to begin the dump to tape once the sync is complete?

Possible, but I wouldn't have time for it to dump all the data if it simply accessed the CIFS share to copy all the data.

Yea, bare metal is handled elsewhere, I just need file level protection. Not sure about Backuppc, it still doesn't help me trigger Bacula as soon as the sync is complete.

Thanks for the help!
