# Backup Wal

`POST /api/admin/backup-wal`

## Request

- Base URL: `https://www.awardflightdaily.com` (the document declares no server; this is the origin it was published from)
- URL: `https://www.awardflightdaily.com/api/admin/backup-wal`
- Auth: none declared

Snapshot the live WAL to a timestamped copy — fast (tens of MB), no big copy.

WAL-ONLY by design (ops choice 2026-06-13): preserves recent un-checkpointed
updates before a risky op or restart. IMPORTANT caveat surfaced in the
response: a WAL snapshot is only restorable PAIRED with the main DB file as
it stood at snapshot time, so we record the main file's size + mtime as the
pairing reference. If the main file is later checkpointed/changed, the
snapshot may no longer apply cleanly — for a fully self-sufficient backup use
/api/admin/backup-db (full rotation) instead.

## Response `200`
