Uploading large files to BackBlaze B2 - Disk Activity? No Upload?

Hi all,

I’m uploading 250GB of data to BackBlaze B2, each file is approximately 40GB in size, so really, only about 7 or 8 files in total.

I have successfully configured rClone and started the transfer, but for 20+ minutes, rClone is scanning my files and seemingly reading each and every byte before uploading. I can see in my activity monitor that rClone is causing a massive amount of disk reads.

Is there a way to bypass this file scan, because it would take >1 hour to scan all 250GB worth of files for upload.

My B2 directory is empty and I am doing a copy, so there is nothing really to sync.


What is your command line? Are you doing a checksum copy?
