Best way to copy data from freeness 7 box to new 8.0.4 box?

[joshnerl]

Title says most of it. I've got an old 7.2 box with about 3.5T of data on it that I want to move to a newly built 8.0.4 box. I know I can't migrate volumes or anything like that, but I'm hoping there's an easy command line option or something so that I can copy directly from one box to the other. They're on a gigabit network and it'd be easier to just let them talk to each other instead of having to drag/drop with my windows machine. Hopefully that request makes sense. This is a one-time deal so i'm thinking rsync may not be worth the setup, but I've never used it extensively.

Hi Josh,

Unless you're setting up the rsync service modules, which aren't that difficult either, there's not much to setup and it's definitely worth your effort. For one, a lot of people migrating their data to version 8 find out soon after starting to copy data that their system will crash if it doesn't have enough memory or isn't setup properly. Rsync will cleanly figure out what has been copied and resume where it left off if it's interrupted. Just create a world readable/writable NFS share on one system or the other, mount it on the opposite (probably easier to mount on FN.7 and share from FN8) and do something like:

rsync -av --partial --stats --log-file=/NFS-path-on-FN8/rsync.log /path-on-your-FN.7 /NFS-path-on-FN8


I'm oh-so-close to publishing a tutorial in my blog on using Rsync to import/backup/copy your data.... I just want to be thorough and accurate, so it's not quite ready to post yet.

Rsycn takes the guesswork out of figuring out where a copy failed if it silently fails or gets interrupted, and you can cancel it and resume later if need be.

Syntax Questions

Ok - thanks for the encouragement. I'm game to check out and try to config the rsync, but I'm missing the syntax in a few spots. I've got NFS setup on both machines, but I'm not sure how to actually mount one machine from the other - how to get them "connected". I've been staring at this screen for two hours and I'm going bug-eyed. I'll try to look around the forum tomorrow and pair it with your suggestion. I'm sure I'll be back with more questions.

I haven't actually ever used FN.7, so hopefully someone else here can jump in and help you with getting a NFS share mounted from FreeNAS 8. After that it should be pretty simple. I know what you mean about going bug-eyed though ;)

I haven't forgotten about this, but I'm having other stability issues that are preventing me from even attempting to do this rsync copy. Will bump thread once I have a stable box.

No problem, I'm preparing to leave on a long vacation for a few months, so I've got my hands full at the moment. I'm also trying to get the Rsync tutorial finished before I leave, so I'll post a link here when I'm done or you when you bump the thread.
