tar has a nice option.... --newer 
( learned that a few weeks ago as posted by jens )

	- i still prefer find | egrep -v "dont copy this stuff" | tar

you'd want to do regular full backups along with daily incrementals...

and both full nor incremental backups must have been done successfully,
else all subsequent backups will NOT be useful, and murphys law dictates
that the directories/files the backup failed on is the one you'd be
wanting to recover from backups

have fun
