Yes, that sounds sensible. Be careful to take measures to ensure that the
backups are consistent; just copying the files that are in use by the
applications may result in inconsistent copies being made, which could result
in data loss. For really good reliability you ought to take a look in to
recommended backup practices for each app you want to sync data for.

There are various performance arguments but if you're running 64-bit on a
32-bit host using Qemu then performance will suffer a lot. I don't think
you'd want to run an active server like that.
