Because of various software bugs, misconfiguration or software interactions sometimes various files are lost from Wikimedia Commons. Sometimes they are restored later, but generally after a long, unpredictable period of time. In many cases they are never restored. Sometimes the files seem to be permanently lost or just nobody knows how they can be restored. In many cases it is not easy to reupload them from other sources as the files were modified/created just for use in other Wikimedia wikis and are not stored elsewhere.
Who would benefit
Wikimedia Commons (and other wikis) users who use the files. They will find Wikimedia Commons as more reliable file storage.
Create a continuous backup of all uploaded files that would allow file restoring by devs in a predictable period of time (few days? a week?) on community requests.
Time, expertise and skills required
- e.g. Hackathon, GSOC, Outreachy, etc.
