MongoDB Backup and Recovery

The logical Backup tool Mongodump and Mongorestore tools in MongoDB can be used to back up and restore operations to the current MongoDB database.

Current database structure:

MongoDB Enterprise > Show DBS
Admin 0.000GB
Dbking 0.000GB
Local 0.000GB
MongoDB Enterprise > Use dbking
Switched to DB dbking
MongoDB Enterprise > Show Collections
Col
Test

--Use the Mongodump tool to back up dbking database data:
