Try HashBackup sometime (I'm the author). :-) I backup a couple of machines from home on a 20Mbps down/1.2Mbps up connection to B2 and have never had any trouble with it. The dev server I backup is around 80GB, has a few VMs I use to build HashBackup on different platforms, and takes around 45 minutes to backup, with most of that time waiting for my slow-ass Internet connection. My last retain/prune took 20 minutes, including repacking 22 remote files. The other nice thing about B2 is they give you a daily 1GB egress allowance, and HashBackup uses that to recover wasted space from deleted files. They bill me $0.53 every couple of months: 25 cents/mo for storage and 2 cents/mo for egress. Can't beat it!
