Backups

CodeOcean persists most data in the PostgreSQL database including submissions and the respective user files. Only binary files that cannot be serialized are stored in the public/uploads folder in dedicated sub-folders with the ID as folder name. Necessary files are temporarily extracted to the container's file system during execution but don't need to backed up separately.

Summary

In order to back up CodeOcean, you should consider these locations:

• config/*.yml and config/*.yml.erb
• The values of environment variables set for the web server
• PostgreSQL database as specified in config/database.yml
• public/uploads and all sub-folders
