Backing up

Hi guys,

I currently use iBackup to back my files to my external hard-drive every morning.

I've just had to buy another hard-drive, which I would like to schedule to back up once a week/month/year etc.

As far as I can see, ibackup will only let me schedule one backup. Can anyone recommend anything that I can input multiple schedules on, with the same features (or better) as ibackup.

Thanks all.
