I, for one, am happy to pay a bit more to keep supporting Backblaze. More than worth the $7/mo to sleep better at night, and the service has worked flawlessly for me.
Maybe my expectations are too high; I'm looking for a UX as beautifully put together as Dropbox (both on Mac and iOS).
EDIT: I will compliment the ease at which I can pick a filesystem tree and snapshot it to their B2 storage system (say, for snapshotting all of my Apple Photos Library at points in time), but it too has a lot of rough edges.
(using ~332GB of storage for backups, which is ~$20/year using Backblaze B2 vs unlimited backups offering; Arq offers five computers and 1TB of cloud storage for $60/year)
It does: https://help.backblaze.com/hc/en-us/articles/217665068-How-d...
It's a minor quibble, but demonstrates a lack of polish imho.
