It might be less confusing and safer to do a total backup each night - but
what happens when your backup time exceeds your backup window {I.E. the
timeframe overnight when the system is not in use}?
I've had systems that take a full 24 hours or more to do a complete backup
- and thsat wasn't on some slow cheap system either - that was running the
latest {at the time} and greatest backup solutions possible.

They're also a necessity in a lot of cases - and anyone who thinks they
aren't is foolish.
