There is an open question about how file persistence works.

The docs claim they persist the filesystem even when they move the container to an idle state but its unclear exactly what that means - https://github.com/cloudflare/sandbox-sdk/issues/102

To me, the docs answer it pretty clearly. The defined directories persist until you destroy().

The part that's unclear to me is how billing works for a sandbox's disk that's asleep, because container disks are ephemeral and don't survive sleep[2] but the sandbox pricing points you to containers which says "Charges stop after the container instance goes to sleep".

Yeah thats basically the issue. If container disks are ephemeral, how are they persisting it? And however they are doing it, whats the billing for it?

Sandbox is built on top of their Durable Objects; the underlying storage is $0.20/ GB-month.

You’re saying the file system in the container is persisted to the durable object storage? That doesn’t sound right.

Whilst it is in the idle state. Not whilst it is stopped.
