Documented steps
Pause a running sandbox: `await sbx.pause()` (JS) / `sbx.pause()` (Python) — by default this snapshots filesystem AND memory, including running processes (https://e2b.dev/docs/sandbox/persistence)
Store the sandbox ID; resume later from any process with `Sandbox.connect(sandboxId)` — resuming a full-memory snapshot restores processes in place
For a lighter, filesystem-only snapshot pass JS `sbx.pause({ keepMemory: false })` / Python `sbx.pause(keep_memory=False)` — on resume the sandbox cold-boots: processes restart and in-memory state is lost
Paused sandboxes are kept indefinitely (no TTL, never auto-deleted); delete them explicitly with kill() when no longer needed
Known gotchas
Filesystem-only snapshots reboot on resume — anything that lived only in RAM (running servers, REPL state) must be restarted by you
Paused sandboxes never expire on their own, so orphaned ones accumulate until you kill them — list and clean up periodically
Filesystem-only snapshots cannot be combined with auto-resume (https://e2b.dev/docs/sandbox/auto-resume)
