I tried to optimize the upload speed of my backup and used more threads. Whenever I use more than one (no matter if it is -thread 2 or -thread 10) the backup sometimes fails with Failed to upload the chunk cdb88423455129335380b205ba393701b3e69d5d1638134aaae18e395bd5020a: too_many_write_operations/
Is is a erratic behavior and I found no reason why it sometimes works and sometimes not. Storage endpoint is dropbox and the backup is encrypted
