General Compatibility

Contabo's S3 compatible Object Storage is widely compatible with Amazon's AWS S3 Object Storage. Not all features of AWS S3 are fully supported. E.g. logging is not supported.

Contabo is using Ceph to provide the S3 functionality. Some tools like rclone do offer direct support for Ceph. Other tools don't. But they usually offer support for other S3 compatible Object Storage providers. We have compiled a list of popular tools and show how to perform the configuration.

For tools not covered in the list, please consider the following information:

  • For S3 URL and credentials. Please refer to S3 Connection Settings
  • specify Contabo specific S3 URLs
  • sometimes access_key is named aws_access_key_id
  • sometimes secret_key is named aws_secret_access_key
  • you may specify the S3 region default
  • path style buckets are used

Tools with descriptions

Tools known NOT to work

These tools are -- to our knowledge -- not working with Contabo's Object Storage

  • FileZillaPro: Seems like the issue is that FileZillaPro forces to use virtual bucket host name, i.e. bucket names in the domain name. As an alternative please use Cyberduck.
  • Plesk: is by default only supporting ftp(s). Also existing remote storage extensions are not allowing the proper configuration.
  • cPanel / WHM: the S3Compatible is not compatible. As cPanel / WHM supports specifying a backup destination folder mounting the Object Storage to that backup folder could be a workaround.
