What do the Replicate Error Codes mean?

Not sure what the error codes mean, but I had to go through support to get the problem corrected with the -51 error. In my case they got in and verified ALL of my units (Source and Target) were on the same Radiator version. Then we made sure that I had the same version of the replicate software on them and also uninstalled the ReadyNAS Remote addon and reinstalled it.

After all of that they also did a restart of the p2p service. (Manage ReadyNas Replicate-->Advanced Settings-->Restart p2p). We did this on BOTH units and then we kicked off the same job again and it appeared to work.

If you have speed issues on the first initial sync (I am doing ours on the LAN before we send the Target off-site). You can disable compression by unchecking it on the backup configuration. That will make the initial sync MUCH faster. Be careful though, because it can kill your bandwidth if you leave it that way after you start the off-site replication (unless you have a big enough pipe).

Just what I have learned so far. I have had to restart the p2p service a few times because it started to fail now. I am not sure if it hangs or what, but give this a try and see if it helps. Worked for me.
