Managing S3 buckets

All objects in an Amazon S3-like storage are stored in containers called buckets. Buckets are addressed by names that are unique in the given object storage, so an S3 user of that object storage cannot create a bucket that has the same name as a different bucket in the same object storage. Buckets are used to:

  • Group and isolate objects from those in other buckets
  • Provide ACL management mechanisms for objects in them
  • Set per-bucket access policies for tasks such as versioning in the bucket

You can list S3 buckets and monitor the space used by them on the Storage services > S3 > Buckets screen. You cannot create and manage S3 buckets from the Virtuozzo Hybrid Infrastructure admin panel. However, you can access your S3 data in several ways:

  • In the self-service panel, as described in the Self-Service Guide.
  • In the legacy user panel or by using a third-party application, as described in the Storage User’s Guide.

Third-party applications listed below allow you to perform the following actions:

  • In CyberDuck, you can create and manage buckets, and their contents.
  • In Mountain Duck, you can mount an object storage as a disk drive, manage buckets and their contents.


To list bucket contents with a web browser

  • Visit the URL that consists of the external DNS name for the S3 endpoint that you specified when creating the S3 cluster and the bucket name. For example, or (depending on DNS configuration).
  • Copy the link to the bucket contents by right-clicking it in CyberDuck, and then selecting Copy URL.
