More than one thread fails with too_many_write_operations

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

This is caused by rate limiting imposed by Dropbox.

It seems like maybe Duplicacy needs to be updated to treat this as a rate limiting response instead of treating it as a fatal error.

Same problem here. Good to know. It’d be good if a more informative error message was shown to suggest to set the threads to 1 (or improve retry logic if more than 1 can still work most of the times).
