If you want to do real backups you should use real tools, like bacula
etc.

Now have Johnny Loser downloading some stuff, say:
$ wget -N ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.12.tar.gz
Are you aware that this file will never be backed up by your script?
Also, what about permission / owner changes etc.?
A backup tool should never work based on timestamps alone.
Best regards,
Wolfgang Denk
