Backup and Restore Options
Explore how to safeguard your MongoDB data by learning backup and restore techniques. Understand how to use mongodump to create binary backups and mongorestore to recover databases. This lesson helps you implement essential data protection strategies to prevent loss from errors or failures.
We'll cover the following...
