Storage Backends

CUBE supports two storage backends, which is configured by the setting DEFAULT_FILE_STORAGE.

See ChRIS backend production services secret configuration files for how to configure CUBE using environment variables.

Supported Storage Backends

Name	Configuration	Description	Recommendation
OpenStack Swift	swift.storage.SwiftStorage	OpenStack Swift is a distributed object storage service	Suitable for multi-user systems, cloud, where reliability and concurrency matter
Filesystem storage	django.core.files.storage.FileSystemStorage	Stores files in a directory on the host. Uses hard-links to efficiently store duplicated files.	Filesystem storage is simple and preferable for single-machine, single-replica deployments
