I have a quick Question regarding the backup process of PSTs. PSTs can become very large as users continue to add emails to them. I know FBackup does only the changes in files from the initial full backup (which is exactly what i want it to do), but my question is does it backup the PST in full each time or is the program designed to only backup the changes inside the pst.
Archive.pst is 1gig in size after initial backup. over the course of the next week the user moves 500MB of emails into Archive.pst making it's size 1.5gig. The next time FBackup is scheduled to run will it copy over that 500MB of new emails into the old 1gig file or will it just see the file as changed and backup the whole file again?
