Imrpove upload speed to B2

Hi there,

I’ve just started using Duplicati and am currently uploading my first backup to B2 storage. Current stats are sitting at “371253 files (1.13 TB) to go at 1.39 MB/s” and the speed seems to hover between 1 and 1.5MB/s, occasionally peaking at just over 2MB/s. My internet connection at home has a maximum upload limit of 100Mbps which is roughly 12.5MB/s give or take a little. Is there anything I can do to maximise my upload speed to B2? I found a Reddit post from the Backblaze CTO claiming that the bottleneck wouldn’t be with Backblaze as long as you can upload with multiple threads. I’m not sure if this is something that Duplicati can do but I haven’t seen anything obvious in the settings yet.

Hope someone can offer some advice?


Just to answer my own question… I have now found the open Github issue for this so no need to respond here.
