Backup and Restore Options
Explore the essential MongoDB techniques for backing up and restoring databases. This lesson teaches you to use mongodump to safely save data and mongorestore to recover it, protecting against data loss from hardware failures, software bugs, or accidental deletions. You will understand how to manage backup files, choose restore options thoughtfully, and incorporate these practices into your data workflow.
We'll cover the following...
Why do we backup and restore data?
A backup is a saved copy of the database at a certain point in time.
