Thanks. That is ok the end of the backup was not needed to be backed up. complicated. But 500gb found its way in to the backup by mistake.
We actually are planning on splitting the backup in to two and will be hopefully getting that going tomorrow. We want to move away from incremental and just do full backups and on fridays do a larger weekly backup.
The rest of the data on the backup seems ok to recover, well it is visible in the recovery selection list. I have never seen a backup software recommend a verify before, does not exactly instil confidence. CA arcserve does not require a verify. Backupexec is kind of annoying. It has the selection lists and policies and all that, seems over complicated than it needs to be. arcserve is just all self contained in one job, easy stuff. Also backupexec went through an entire 8 hour backup without failing and at the end we found out that the exchange backup failed due to credential problems, was just a setting wrong on the job. Still annoying that it does not error out at the point and send notification like arcserve would.
