This post covers the other side of that coin: crash-consistent cloning. No write freeze. No backup. No point-in-time recovery. Just a raw volume clone that SQL Server recovers from automatically when you attach it.</p> <h2 id="what-is-a-crash-consistent-snapshot">What Is a Crash-Consistent Snapshot?</h2> <p>When people talk about snapshot backups for SQL Server, they often jump straight to application-consistent snapshots, the kind where SQL Server is asked to freeze write IO before the snapshot. That freeze guarantees every page on disk reflects a logically consistent database state.</p>
