Replicate data to newer ReadyNas
I currently have a ReadyNAS Pro4 that I will be replacing with a newer RN626. The older model is running firmware RAIDiator 4.2.31. The unit is set up with active directory integration and is used to backup desktop computers in our division. Each user has their own folder via active directory. As the administrator I do not have access to the data on those folders.
I would like to backup or clone all the data from the old ReadyNAS to the new unit including all the data in each of those active directory users folders (i.e. clone them to new folders in the new unit but they are still locked to the active directory user). When I switch over to the new unit then all new backups will go to the new device instead of the old device.
Is there a way to do this kind of device cloning or backup?
thanks,
Alan Stein

Come to think of it, rsync synchronisation might just work right off the bat, it would for local users (so long as you created the user accounts first).
Again, the home folders are only created after the user accesses the NAS with their credentials using SMB. At that point, the system will create a btrfs subvolume.
If you simply run rsync, you will almost certainly end up with an ordinary folder instead of a subvolume.
An alternative here is to provide each user with a script that would migrate their data from their PC.

Actually you do have access - whether you want to use that access or not is of course a different question.

I don't use these folders myself. You should be able to migrate them with rsync backup jobs (and you can certainly migrate public shares that way).
One challenge is that the folders aren't normally created until the users access the NAS over SMB.
I've only used local users, not AD users. Perhaps, you could deploy the new NAS, empty, but keep the existing NAS for now. After the users sync at least once, you could then continue with an rsync synchronisation. Come to think of it, rsync synchronisation might just work right off the bat, it would for local users (so long as you created the user accounts first). Alternatively, you could run a backup job from your old NAS to your new NAS, right from the dashboard, or if you already have a full backup, restore it to the new NAS. There are several options to get the data across, the tricky bit is fixing the access rights.
I suggest you try one initial account (your own?), to see what happens.
As StephenB mentions, if you are the admin, then you *do* have access to every file on the entire storage system.

Now I am curious how a backup strategy for the NAS works (assuming restore doesn't actually fully restore everything)?
