Replit Filesystem Wiped on Redeploy

Your Replit app stores user uploads, generated files, or cached data on the local filesystem. Everything works fine until you redeploy or the container restarts, at which point all those files are gone. Users report that their uploaded images, documents, or other files have vanished.

Replit's deployment infrastructure uses ephemeral containers. The filesystem is rebuilt from your source code on every deploy, meaning anything written to disk at runtime is temporary. This is a fundamental architecture constraint, not a bug.

This problem becomes critical when your app stores user profile pictures, document uploads, generated reports, or any file that users expect to persist permanently.
