No bacula, but this is what I use from time to time to take live copies
of a filesystem:
# tar -cvzf - / | ssh steve@server.domain.com 'cat > fsbak.tar.gz'
Note that you will have to implement SSH keyed authentication to
automate it all-around.
Also note that the above will create a tarball on the remote server that
contains the ENTIRE directory structure. Substitute '/' for '/usr' or
whatever structure you want backed up.
This procedure can also be used to untar the tarball onto a new disk,
and boot right from it. (Although changes have to be made, and it's not
bulletproof).
A Perl or shell script can easily automate the naming of the backup file
on the remote system, and even recycle ones that are N days old.
