## TL;DR

Database backup evidence tells an agent whether data loss can be recovered, which restore time is valid, and which replica or instance should be used.

## Core Explanation

When an incident involves deleted rows, bad migrations, or corrupt writes, the agent needs restore evidence before proposing destructive repair. A useful checklist includes the latest base backup, write-ahead log or binary log availability, retention window, restore target time, encryption key, and restore test history.

Point-in-time restore is not the same as undo. It usually creates a restored instance or cluster that must be validated, compared, and promoted or used as a source for selective recovery.
