I`ve made some corrections to supremecenterhosting update, unfortunatly he did'nt realise the automatic function relies on the date appended to the file, so by setting that to Y only, he made the interval 1 year!

I`ve made the following changes:
Reinstated time stamp, but without seconds as not needed.
Added an SQL so you can set interval in admin (In Module Options).
Added option to delete old backup up to a maximum age, I recommend setting this to 12 hours, if you set it too long you will always delete old backup.
Made messages more informative.

Spotted error in delete function, corrected that & time calcs..
