@DustinB3403 said in Syncing massive amounts of changing data to BackBlaze B2 via Linux:

@Pete-S At my workstation I'm getting 225Mbit/s down and 155Mbit/s up (clearly not symmetrical there. . .) but not bad either considering I have nothing special configured for my workstation.

On a second test I noticed this A connection of 152.8 Mbps upload would backup 1,650 GB in a day

So this very well could be feasible to do.

Yes, that's not too bad. It could work. As @dafyre and other mentioned you should give it a try.
$.005 per GB is $5 per TB. So get an account and upload 2TB of random data to see how long it takes. Only going to cost you 10 bucks to find out.
