RDS-WORM stands for Write once, read many. As this name suggests, it is a resource for storing research data with high protection requirements. Once stored, data can never be deleted, changed or overwritten. This ensures a high level of security when storing the data.

Warning: Once files have been stored in a RDS WORM resource, they cannot be deleted or edited! Therefore, this resource type is only suitable for data that emergency requires such a high level of protection. For all other research data, please select another resource type, such as RDS-Web or -S3. Otherwise, careless use of an RDS-WORM resource will unnecessarily waste storage space that will not be available to other researchers.


Please use WinSCP, Cyberduck or MinIO Client according to the instructions on the respective subpages. We cannot provide support for the functionality of other applications (e.g. rclone, S3CMD).


RDS-WORM are object-based storage units with "write once, read many (WORM)" functionality for research data. RDS-WORM is based on the same technology as RDS-S3.


Once allocated, storage space cannot be reused, not even by the project owner or system admins

**What changes for me if I want to use RDS-WORM?
As with an S3 resource as well, RDS-WORM cannot ensure that the metadata will be stored in Coscine. Therefore, a storage request via the Jards platform is required to describe the planned workflow of data storage as well as annotation with metadata. Since with an RDS WORM resource, once data is stored it cannot be deleted, the storage request asks for more stringent criteria. This can ensure that no storage space is wasted. RDS-WORM is based on the same technology as RDS-S3, so all further information can be found on the related pages for RDS-S3.

The request document for RDS-WORM resources can be found at Storage Space Management.

How does metadata management work for WORM resources?

Metadata that, like the associated data, should no longer be modifiable must be stored directly in the S3 bucket via additional files (e.g. README files). Metadata that is maintained via the Coscine web interface remains editable.

What happens next?

RDS-WORM is based on the same technology as RDS-S3, so you can find all further information on the related pages to the RDS-S3 resource.
