Question

Is that possible to use custom S3 compatible storage for backups?

Answer

Starting from version 1.1.0 Amazon S3 Cloud extension there was support for custom S3 type storages included: Plesk explicitly supports DigitalOcean, Minio, and OpenStack. 

To configure an S3-compatible storage:

1. Go to  Tools & Settings > Backup Manager > Remote Storage Settings > Amazon S3 Backup.
2. Under “Service provider”, select “Custom (Minio, OpenStack, etc)”:
   
3. Fill in all the fields. Pay particular attention to the “Bucket” and “Path” fields. A bucket is a place that you create to store data in an S3-compatible storage. You need to note the bucket name and paste it in the “Bucket” field. In the “Path” field, you need to paste a path to the directory inside the bucket where you want to store backups.
4. 
5. Click  OK.
