I’ve been using Backblaze B2 for cloud backup for the better part of a year. I started out accessing it over a 50 Mb/s link. A couple of months ago I upgraded to a 250 Mb/s link, and I was interested in seeing how that affected my upload rate. Today I got around to looking at what happened when uploading a series of 300 MB files:
These graphs are from the Sonicwall firewall’s monitoring screen, and show all Internet traffic. The update rate is once per second, and the total timebase is 10 minutes. The top graph breaks down the traffic by application, and Backblaze is far and away the biggest bandwidth user. The two lower graphs show download rate on the top, and upload rate on the bottom. Backblaze is coming very close to accepting the maximum wire speed on the peaks, but on average the performance is considerably lower. And what are those gaps? Looking at the Goodsync log:
We see that every so often Backblaze goes on vacation for a few seconds. Every few hundred GB, the vacation gets so long that Goodsync gives up and has to be manually restarted. This was the case with the 50 Mb/s connection as well. The average rate is about 100 Mb/s.
So, some good and some bad. In the scheme of things, this is acceptable for me.
