Unison Support?

Well, if dpkg is implemented on the readynas (I don't know), you can probably install it easily enough. After radiator 4 is released, I'd be willing to try it myself.

Although it isn't true that running unison locally misses the whole point - after all, you are still achieving file synchronization. It's just a whole lot slower than it ought to be. But better than nothing.

I wouldn't take that bet.

Hey Brendan. Ever since you wrote that, I've been wondering if you're right... thinking you probably were, but I wanted to know for sure. So I had a mental note to actually test it, once RAIDiator 4 shipped.

I just finally updated to RAIDiator 4, and (with a not-too-carefully tuned setup, for example I'm using the normal ethernet 1500-byte MTU, not jumbo frames), I get around 25MB/sec reads. Running md5sum locally, I was able to checksum a 700MB file in 27 seconds. Running md5sum against the same file locally on the NAS, it took 67 seconds (barely 10 MB/sec).

So you're right, and I lost the bet: the ReadyNAS can drop packets on the wire a lot faster than it can checksum them with md5sum.

I don't know exactly how rsync computes checksums and whether it's more or less CPU intensive than md5, but in the spirit of things, you win and that makes running rsync/unison on the NAS a lot less attractive, assuming a fast network (if you were running across a slow link, then of course the link becomes the bottleneck instead of the ReadyNAS's CPU and the tables may turn).

Is there anything new on that issue?

I would like to use unison to sync between my computer and my NAS. Is this possible right now? And how can I install unison on the NAS?

unison can be compiled for readynas but is not really a good soft because soemtimes it goes silly and you must restart the whole sync

This would also be of great help to me!

If Netgear would add unison support it would be very valuable.

Definitely very useful! Would be perfect for offsite backups.

Just posting the solution in case anyone else finds this thread:

• Download and install the EnableRootSSH and APT add-ons from http://www.readynas.com/?page_id=617


• Log in as root using ssh
  

  apt-get update ; apt-get install unison

And you're done.

HTH,

Hi, this is my first post. I just bought two ReadyNAS NV+ V2 (waiting for HDDs to arrive however..) in order to be able to work at two different places, but sharing the same data. I thought that Replicate would achieve that, but I realized that is more like backing up data remotely. And then I stumbled upon this thread...

Will I be able to use unison on my ARM devices? Has anyone tried it, and were you successful?

I did find a good tutorial of how to do it, if it is possible: http://www.cyberciti.biz/faq/unison-file-synchronizer-tool/

Kind regards,
Andreas

Has anyone got this to work on any of the readynas units?
I am looking at 2 way directional sync of NAS boxes in London and Manchester. There are only 2 user at each end.
