I got into a debate with some other people about doing a full backup each night vs. full 1x a week, then incremental or differential.
on the pro side of full each night, restores are easier (but hopefully restores are infrequent / rare... but when you need to do it, you don't want to waste time grabbing different tapes), any 1 tape has all the data up to that date.
on the con side - backups take longer (but as long as it runs overnight / done by the morning, so what?), more wear and tear - backing up gigs of data each night vs. a couple / few meg that changed recently) - you'll have to replace the tape drive sooner than full / incremental
on the pro side of full / incremental - faster backups, less wear and tear on the tape drive / tapes.
con - restores take longer, have more tapes to have on hand to do a restore.
