What is pause and resume?

Pause and resume lets you stop a sandbox and start it later with its files, and sometimes its memory, intact. You usually pay less, or nothing, for compute while it is paused.

How it differs from a snapshot

A snapshot is a copy you can restore many times. Pause and resume is about one sandbox: it stops, and the same sandbox continues later.

What to check

Check what is kept (files only, or files and memory), how long a paused sandbox is stored, and what storage costs while it is paused.
