The whole point of Duplicity is encryption, so if you *don't* want
encryption rsync is what you need.

A basic rsync backup would be:

rsync -avz --delete /source/ /target/

-avz means preserve all file permissions, recurse subdirs and compress
the transfer to save bandwidth. The --delete option deletes files on the
destination, which have been deleted on the source.

Note the trailing backslashes - the prsence/absence of these affects
where rsync places the backups on the destination.

Have a look at rsnapshot (requires Perl) and rdiff-backup (requires
Python). These are wrappers around rsync which can do an awful lot of
extra things.
