Automatic MongoDB Database Backup and Old Backup Cleanup
This script backs up the MongoDB database and stores it in the /opt/mongoyedek folder. If there are multiple backups, it keeps the newest 2 and deletes the others.
If you are going to use this script, first set it up in your test environment and follow it for a period you find appropriate.
To prevent the server’s disk from filling up in case there are too many old backups or they are not deleted, either define a separate disk space for the address where you will take backups, or also consider moving backups to a location outside the server.
