You can tunnel any connection where you can specify the host and port
to use through ssh. In Bacula, you could set up the tunnels using a
run before job script.
A regular VPN might be easier to maintain, though harder to set up.

That's a bit limited for backup purposes of large data sets.

Well, it's quite important to know where you want your backups to end
up. Assuming you want them all consolidated on the HomeServer, you'd
need some VPN/ssh tunnels to all the servers you want to back up.
Once those exist, it's a rather standard situation to set up Bacula
accordingly.
If you need to keep backup data on te different sites because of the
traffic limitations, you'll end up with a number of SDs - one in each
location - but you can still control those with a single DIR instance.
Getting a usable setup might be difficult because the SD address in
the configuration needs to be valid both for the DIR and the FDs
accessing that SD - again, a VPN might be useful, but some careful
/etc/hosts edits on all the sites might do the trick.
If all your servers are accessible with public IPs / DNS names, that's
not much of an issue, though.
More specific advice would require some more knowledge about your
network layout - are those heavily firewalled networks, do they share
a common DNS zone, or are they even networks completely separated from
each other?
