Sure but backup is mostly data in (free on B2). Data out is rare, if ever.

If i wasn’t backing up 12TB+ I would actually go with rsync for the features though.

Borgbase looks interesting, too.

I had never heard of rsync.net until now. I like the idea but it seems more expensive than B2. $15/TB vs $5/TB. Am I doing the math wrong or reading it wrong?
