Session Backup
Domain: Sessions & Persistence
Motivation
Backing up sessions means copying the persistence root — the directory tree of per-session logs — to a safe place before risky operations like updates. Because every durable fact lives in those files, a copy of the root is a complete backup of all session state. This is the same operation as backing up $DSH_HOME session data.
Concrete Example
Copy the dsh-session-persistence-jsonl root directory (all <normalized-cwd>--/<session>/ trees) to preserve every stored session.
Analogy
Zipping the entire saved-games folder before an OS upgrade.
