How does Point-in-Time Recovery (PITR) work using oplog tailing and filesystem snapshots?
❓ Interview Prompt: Explain Point-in-Time Recovery (PITR), restoring base filesystem snapshots, and replaying Oplog events to specific millisecond timestamps.
Point-in-Time Recovery (PITR) restores a database to an exact millisecond timestamp by restoring a base snapshot and replaying Oplog entries up to the target timestamp.
Code Implementation Example
typescript
console.log('PITR: Restore Base Snapshot -> Replay Oplog to Target Timestamp');💡Point-in-Time Recovery workflow.
🎯 Interview Key Takeaway
Deploy PITR to restore database state to exact millisecond timestamps prior to catastrophic data corruption events.
