This is risky, as you don't keep any change history then. Imagine you
erroneously modify some files the wrong way. If you don't immediately
realize it and your rsync-backup runs, then these wrong modifications
will also be applied to the backup. The correct version of the file
will be gone for ever then.

Better use tar and do incremental backups. (There is a reason why
some procedures are standard everywhere.)
