Using Duplicati - 2.0.3.3_beta_2018-04-02 & Minio RELEASE.2018-10-06T00-15-16Z on different machines on the same LAN.
When using Duplicati to backup to my Minio backend, Duplicati errors out with “Object name contains unsupported characters.” message at the bottom. Nothing shows up in the minio log.
At the same time, I see multiple threads on here that suggest Duplicati+Minio is working fine.
This last one specifically says Minio is a supported destination though I don’t see it in the list, and ‘S3 compatible’ often reverts to ‘Amazon S3’ when I try to edit the settings if that makes any difference.
I tested it, and /source/ (default) does not work; /source does work but doesn’t actually create a /source folder in the bucket. All the files are dumped straight into the bucket root, which is entirely functional, but cumbersome if you wanted to backup several machines without creating unique buckets for each one.
If you want to test it out yourself, I can PM you with credentials and give you access to a bucket.
This might be relevant for better implementing support for Minio. It describes differences in the API vs S3:
