I am using bacula v9.4.4 community edition on CentOS 7 server.

I am trying to use minio to send backup to backblaze storage.

From the logs it looks like quite a few hiccups occur with messages similar to this:

msg=S3_put_object ERR=ConnectionFailed

At the very end of the backup log file there is a message like this:
Termination: Backup OK -- Upload to Cloud failed

When looking at the smaller "part" files that make up a volume on the backblaze server, the parts that had errors in the log message appear to have 2 revisions of the file and the total file size of that part to be roughly double of the designated size of the part. I assume this not to be horribly abnormal as I assume the part is uploaded twice. Although the bacula log file does not really say that the volume was re-uploaded, I am just guessing that is what happens.

Anyway, to be safe, I thought it might make sense to use the "cloud" functions from bconsole to sync the volume to the cloud. When I choose the "cloud" option and choose the appropriate storage, pool, and volume, it looks like the upload is unsuccessful and the following error is given:

3999 Error with the upload: ERR=SignatureDoesNotMatch

As far as I can tell, that may be a minio/aws error, and I can't find anything necessarily related to bacula with the error.

Is anyone here familiar with this error, and know the resolution?

Thank You.

-Scott
