bi-directional replication

[Chris Stankevitz]

Is there anything out there besides microsoft's DFSR to perform bi-directional replication of a single dataset? I have two sites that want t operate on the same data without explicit commits/merge/conflicts like git/svn.

Right how I use ZFS with multiple datasets, each of which is writable at only one location. Then I send/recv them at night.

Thanks,

Chris

Why not use site-to-site VPN and just replicate data to the second site for disaster recovery?

Mlovelace,

The users already have that option. But because the files are so large they need local copies. I accomplish this right how using two datasets at each site. Users at site A can only write to dataset A. But they have read-only access to dataset B, which is updated nightly using zfs send/recv.

How would it work when two people edit the same file? This is still a real problem.

If that's not a problem in your environment, then something like Unison.
