I'm asking as a genuine question, where or how should people backup large datastores? Also what counts as too large? I've heard Backblaze doesn't cover NAS so i wouldn't be able to backup my 2TB zfs RAID, but like is that too much?
I want to do 3-2-1 for my homelab to preserve all pictures in my immich and the backups of my LXCs and VMs, but I'm just not sure how to go about it, and I was considering archives of those files + backblaze...
For a NAS, you can use Backblaze B2, but they certainly aren't the cheapest. B2 doesn't have the limitations that the personal and business plans have, but you pay by the TB.
There are lots of cloud backup providers. Just make sure it supports the OS on your NAS. Any of them that claim to be unlimited will not truly be unlimited.
