i use rsync.  it works wonderfully for local and remote file/filesystem
synchronization.  another great thing by andrew tridgel (creator of
samba).

has all the options i want, and many great others i never thought of,
delete, keep deleted, exclude files, preserve permission, preserve gid/uid

only copies the difference of the file/filesystem instead of the entire
file/filesystem/blog.

can also work on top of ssh for compression and encryption (good if your
cpus are faster than your lines (compress & encrypt versus bandwidth))

then configure ssh for passwordless login (in you own secure network) and
put the scripts in crontab and you have a worriless backup solution :)
