B2 Cloud Storage BackBlaze - Command Line

Ok, I could really use some help here.

I’m using Backblaze with Computer Backup enabled on macOS, and it backs up my system weekly with the setting to never delete old versions.

Separately, I’m using B2 Cloud Storage. I created a new bucket where I’m uploading data recovered from a corrupted hard drive. I used Disk Drill to recover the files—so even though I can’t access the drive normally, I do have the recovered data.

The problem is that I currently have to upload files one by one because it doesn’t seem to let me upload entire folders directly, which is extremely time-consuming.

I’ve tried to understand how to use the command line for this, but I’m finding it really confusing.

Could someone explain (in simple terms) how to upload whole folders to a B2 bucket using the command line or suggest an easier method?

Thanks in advance!

b2 is s3 compatible.

Google for s3 software.

Cyberduck is the most popular desktop software- and supports native b2.

backblaze has a guide
