If you use a dedicated host, you might as well abandon self hosted. HE is
nice for small setups with the HA built in for extra fun, but once you
scale, it might not be able to cope and you'll need real hardware. You're
running a heavy-ish java engine plus two databases after all.

So as I said, all I do is add the engine-backup command to cron on the
engine, and then my backup server comes in and pulls out the files via scp,
also through cron. Nothing fancy really, but it lets me sleep at night
