You can tunnel rsync through ssh, this way you only transfer changes,
you transfer changes in a secure fassion, and you don't need diskspace
to create a backup file that is then transfered, I use:
/usr/local/bin/rsync -Cuvaz --rsh="ssh" /path/to/src/ \
<myuser>@<myserver>:/path/to/dst
The only, but really anoying, problem about rsync is that /path/to/src/
is not treated as /path/to/src - the above does what you expect: mirror
all in src to dst.
So, while you try figuring out the /'s rsync to an empty dir, then you
can easily delete.
Cheers, Erik
