Backblaze - Transferring a Paid License
You can move a paid Backblaze Computer Backup license from your original computer to a new computer or installation using two methods: Inherit Backup State or Transfer License. Both methods properly license the new installation, but the way in which it is handled differs.
For Mac users, if you used a Migration Assistant or a Time Machine backup to transfer your data from the old computer to the new computer, you must uninstall and reinstall the Backblaze software before you proceed.
