In this case the 'Save Files to B2' option won't be useful to you, as the NAS software or third party has a completely different encryption and format than Backblaze might use by default. HOWEVER -> if what you want is a 'live backup' where you add new files to your NAS, then it might make more sense to get all the files correctly located on your NAS then either use the NAS internal software to mirror the files up to B2, or a third party piece of software such as Arq or Duplicity or Duplicati. You can move up to 10 TBytes at a time!Īfter that is complete (for 10 TBytes it might take a few days), then after it is safe and sound in B2 you can delete your Backblaze Personal Backup and 'disable Backblaze Personal Backup' option in your account and you will no longer be charged the $5/month -> you will only be charged after that for the files in B2 according to size. If you just want super long term cold storage, let Backblaze do it for you on the server side! Just sign into your Backblaze Personal Backup account here: and after signing in, go to the 'View/Restore Files' link on the far left of the page, then look for the 'Save Files to B2' option. I assume you have uploaded it into a Backblaze Personal Backup account? It matters what 'form' you want it in B2. Is it easy to migrate my 10TB to a B2 account

(Be sure to scroll down that page, it has lots of content and info.) There is a B2 cost calculator and price charts here: Also, it is totally free to upload the 10 TBytes into B2, but there may or may not be some (very very small) charges for transactions.
