It’s kinda wild that for home NAS backups it’s still cheaper to buy a low-end Synology with a big-ass HDD, put it somewhere != home, and backup to it.
Famously-cheap Backblaze B2 is $144 / yr for 2 TB. A Synology DS124 is less than $200 and 4 TB HDDs are less than $100. Two years & you’re ahead. Add more TBs & it’s even faster. Of course, it’s even cheaper if you’re willing to fiddle w/ Raspberry Pis.
Holds up if you include electricity bills: backup NASes can be switched off most of the time.
