# oz0 server backup record

> Record that the management database was backed up at a time with PostgreSQL's own tools (pg_dump, pgBackRest, a volume snapshot), as `server backup` records its own.

For: Operators and developers looking up a command.

Record that the management database was backed up at a time with PostgreSQL's own tools (pg_dump, pgBackRest, a volume snapshot), as `server backup` records its own. `oz0 doctor` warns when the newest recorded backup is older than the newest tenant payload key: histories written with that key could not be opened after a database loss. TIME is when the backup's snapshot began, in RFC 3339 (2026-10-08T03:00:00Z).

## Usage

```bash
oz0 server backup record --taken-at TIME [flags]
```
