What do you back up?
Is the selectionlist and the backup destination the same in both jobs?
Did you create the jobs using a policy and a selection list?
Are you using backup (differential and full) with "modified time" or "archive bit" option?
I would recommend:
- create a selectionlist with the ressources of the machine you want to backup
- create a policy with two templates
- one template for the full backup using archive bit and a schedule for running weekly
- one template for an incremental backup using archive bit and scheduled for running daily
Then, let the jobs run, and see, if they work. I would recommend incremental backups, because they do not backup such a big amount of data and the restore is not very complicated with incremental backups, when done from disk. Differential was invented, because it has been quite annoying restoring from incremental backups from tape.
