Re: What to use for synchronizing data on multiple hosts with NetBSD?

What is the best solution on NetBSD to keep data on three machines in

changes may happen on all of them, and I don't want to lose access to
the data if the central machine is not there.

1. NFS is not a solution, because the data is only available if the
server is there.
2. rsync is not the solution because I have to manually check which
machine had the latest changes to the files.
3. hg/git/... is not the solution because it's inefficient for this
use -- it duplicates the data (I'm interested in binary data, not well
4. afs is not the solution, because I can't get it to work on NetBSD

What do you recommend for this use case on NetBSD?

For this task, I used to use net/unison{-devel}.
It can synchronize file hierarchies with a bi-directional synchronization, so that you always get the latest version, and will ask in case of conflicts. It depends on ocaml (and eventually lablgtk if you want a gui), and works fine on netbsd, among others, and is pretty efficient.
