You can put Bucardo anywhere, and have backup copies on other servers
ready to go. While you could even use Bucardo to replicate the bucardo
database :), it's small enough that a pg_dump will suffice.

It's unclear what your scenario is as far as failing slaves, but Bucardo
should be able to handle that. In the future it will be automatic, but
generally, if a slave goes down, you set that database as "inactive"
inside Bucardo and restart it. When it comes back up, just set the db to
"active" and restart Bucardo again.
