Repository Backups

Looking into upgrading controlcenter to 5.2 sp5. First thing in the installation guide is to check that the hot/exp backups have been carried out successfully. On checking the files have not been updated in 12 months. I have no idea why the backuops on both servers have ceased on the same date.

Anyway, How do i get these running again as scheduled tasks rather than just running them through the repository maintenance as one off backups?

Cheers
