Unraid Duplicay Back up to BackBlaze B2 slow

I run it on a docker container in Unraid and easily get speeds up to my max upload, my hardware is definitely lesser than yours.

I run -threads 10 and that’s the only modification i make to default backup.

Have you checked your unraid logs while this is running?

Sorry was waiting on the original backup to finish.

Here are the results of the benchmark, thank you!

Also no errors in any logs - all is well.

So the upload speed with one thread is 1.15M Bytes/sec. How about -upload-threads 4?

I think that’s ultimately my issue.

This was the benchmark command I ran

cd /cache/localhost/0

/config/bin/duplicacy_linux_x64_2.7.2 benchmark -storage BackBlazeB2FilesBackup -upload-threads 4

I always get the same 1.15M, I have a screen shot confirming it runs with the requested “4” threads out a few posts up. Reporting image here

So with 4 threads -threads 4, 8, 12, etc option I always get single thread performance. on the upload.

Thanks to all!
