We use their ‘B2’ thing (which is pay-per-GB), not their ‘personal backup’ thing (which is the one without Linux support and IIRC is ‘oh it’s unlimited! don’t use Too Much though! how much is too much? oh it’s unlimited!’). B2 is “S3 compatible” storage not a regular thing, so it’s kind of a hassle to work with, but some backup tools can back up to S3-style storage (we use restic for that).
Backblaze storage is around $6/TB/mo last I checked
No Linux support
