Backblaze backup fails intermittently?

“Failed to send request head https://f000.backblazeb2.com/{...}: [Errno 2] No such file or directory”

This happens for a few blocks and then the backup just quits.
Then sometimes I can run and the backup completes.

Please advise?

This error happens when the root certificate authority file needed by making an HTTPS connection can’t be found. This file is packed in the executable and expanded to a directory /tmp/_MEIxxxx during the execution. If it becomes missing then maybe some other process deletes the file? Is your /tmp ramdisk full?

I think I am having the exact same problem as the OP. Is there any way to get some better logging when this is the case (/tmp filling up) or somehow increase the capacity of the /tmp slice?
