I basically just have a cron job setup to run b2 sync at 2am, and then kill it at 8am. It generally doesn't take that long to run now, but when I was first syncing everything (couple hundred GB) this allowed it to take place over several days without affecting my daytime bandwidth.
Btw, they should include Amazon Glacier on the pricing page comparison, not just S3.
What is it missing that Crashplan and Backblaze Personal Backup have?
$5/mo of B2 is about 1TB of storage, so if you're above that then maybe cost is a factor?
It's cheaper then backblaze, slightly. It's not really comparable, because it's not distributed and there is real risk of data loss. However, for my needs, it works as part of a comprehensive backup plan. I get a bit more bang for my buck and more flexibility.
Seems to work OK so far. Won't be as cheap as their unlimited plan but I'm OK with that.
I'd have to say the 30 day retention policy is one of the main issues. I'd also add their lack of restore in their client myself is a big issue.
