I'll be buying a new NAS (Synology) soon, and I wanted to check the best way to move the data from my current NAS (QNAP). The QNAP is a one-bay unit, but the new Synology is a 2-bay, though to start with I'm just going to continue using the single drive (second drive will come later this year).

I know I can't just swap the drive out of the QNAP and into the Synology, but is there a better alternative to copying the ~1.8TB of data from the QNAP onto an external drive, wiping my current drive, then copying the data back onto the freshly wiped drive in the Synology?

Put a disk in the new NAS and copy the data over. I would use Teracopy with verify turned on, it checks hashes to ensure the data is written correctly. I don't think there's a practical way of doing this if you only have one hard drive, unless you have a lot of available local storage on your PC.

Another option if you can SSH into both NAS boxes then you can use rsync to duplicate the data from one to the other. But if you only have a single disk you want to move from the old to new NAS the data needs to go somewhere.

Restore the new one from a backup of the old.

If you were going from QNAP to QNAP, then on most QNAP devices you can just take the drive(s) out of the old QNAP, and put into the new one (in the same order if multiple drives), and all config/settings are kept.

 

This is what I did recently, going from a 2 drive TS-253 Pro, to a 4 drive TS-453be.
Very easily moved the 2 drives to the new system, plus I then added an extra 2 new drives, migrated the existing raid 1 (2 drives) to raid 5 by adding the 2 new drives, and expanded the storage pool and volumes.
Easy as.

 

If you are set on changing to Synology, then as above, use something like rsync, but setup your new Synology first (Raid 1?), and copy data from old to new.

I'm going to be using the same disk that's in the QNAP in the Synology. A second disk will come later in the year. So I think my best bet is to try and copy stuff to an external drive (I have one that might have enough space, or might have to use a second disk for some of the data), then wipe the disk and install it in the synology, then copy back again.

So, a related question. I have two folders from my QNAP NAS backing up to 2 buckets in Backblaze B2. Is there a way to set things up so I can continue to backup to those buckets but from the Synology NAS, without having to reupload the files all over again?

Why not just setup the new NAS and pull it all down to the new NAS so then you know it's all in sync? That would be the safest option IMHO.

The only problem with that is the data in the buckets isn't a complete backup (I. E. the QNAP NAS never managed to upload all the files. It would be better if the Synology could just continue where the QNAP left off, but I don't know if it'll do that.
