The solution to persistent data storage is to usually connect your Fly App to a separate database or object store. If you need hardware-local disk storage on your Machines—for example, if your Fly App is a database or if you want to use LiteFS—then you can use Fly Volumes.
The Fly Machines in your app provide ephemeral storage, so you get a blank slate on every startup. For persistent storage on Fly.io, use Fly Volumes. You can attach volumes on an app directly, or run a separate database app with volume storage and connect an app to that.
- Fly Volumes: A Fly Volume is a slice of NVMe disk storage attached to the server that hosts your Machine. Read the Fly Volumes overview to find out if volumes are the best solution for your use case.
