I need a way to back up my NAS. I can't exactly afford to have a full 3-2-1 strategy cause as 15yr old, I don't have any offsite places to store data nor the money to pay a subscription. But what I do have is my PC, ThinkPad, and I could get more drives/computers if needed.

I don't exactly know how a backup system would work, would I need the same amount of storage my NAS has? Could backups be automated (running Ubuntu server)? I've seen people use an external drive or another NAS, and while I can do that, it'd be costly to maintain the same capacity with another NAS. I store my data in either immich or FileBrowser containers, one for photos/video, the other for 3D models, documents, etc.

I'm realistically only trying to protect against the NAS itself having some sort of failure with disaster protection not being my top priority, though if I can integrate that into my backup strategy without too much hassle, that'd be great.
