Incremental disappear after deleting some jobs

Hi there,

I have a troublesome on Backupexec 2010R3. Some links have been broken after a shutdown on servers, electrical maintenance. When i launch server, i dont check links for backup are up... So 2 days after, i will see it. Incremental jobs are waiting ~~, to not have to launch them, i clicked and delete it. But now i have only full backup job and nothing... no incremental jobs.

How can i restore jobs as previous ? Why jobs can't pop ?

Thanks a lot !
