Mirror existing NAS to new NAS?
Hi everyone, After my close call with almost losing a volume (viewtopic.php?f=66&t=55910), it is time to seriously consider moving to dual-redundancy for my main NAS with a complete kept-up-to-date...
here is what I do/did when upgrading to new nas
create NFS backup jobs for each share I want to copy to new nas, I would run them on the new pro since its more powerful than the old.
the x86 devices can run them in parallel, but I would try to keep it to 2 or 3 max at the same time.
after a NFS job completes, edit the backup job (click the # button) and change from NFS to RSYNC, make sure the source/destination fields are correct, then run the rsync job.
99.9% of the time, the NFS job will have done a perfectly fine copy, however following up with rsync will ensure that you get a bit for bit exact duplicate from the source to the destination.
since the data is already there on the destination, the rsync job should take a few seconds to less than minute if you have a huge number of files.
once the rsync job has finished, you should make sure permissions are set/reset to however you want them configured.
