Back up MongoDB Atlas to a bucket you own

Atlas backups live in Atlas. Here is how to send an independent, restore-tested copy of your MongoDB Atlas cluster to storage you control.

Jan Svabik

MongoDB Atlas takes continuous and snapshot backups, and they’re solid. They also live inside Atlas, tied to your Atlas project. For anything you can’t afford to lose, a second copy in your own cloud storage, on your own retention, is cheap insurance. And a backup you’ve never restored is a guess.

Norcube Backup gives you an independent copy in storage you own, restore-tested on every run.

What it does

Point Norcube at your Atlas cluster with a standard connection string. On your schedule it runs mongodump, encrypts the archive, and writes it to a bucket you control. You can download any backup and restore it with mongorestore, independent of Atlas and of us.

Connecting Atlas

Two Atlas specifics. First, the connection string: use the standard mongodb+srv:// string from Atlas’s Connect → Drivers dialog. The SRV scheme discovers your cluster’s nodes and implies TLS, which Atlas always requires. Second, and this is the step that trips people up: Atlas’s IP Access List blocks all inbound traffic by default, so you must add Backup’s egress IP 18.196.207.101/32 under Network Access. Then create a read-only database user for the dump. Full steps are in the MongoDB Atlas backup guide.

Prove it restores

Every backup can be restore-tested: Norcube replays the archive into a throwaway MongoDB engine and confirms your collections and documents come back. For MongoDB the verdict is a straight pass or fail, so you know whether the backup is recoverable, not just that the dump ran.

Backups are only real once you’ve restored one

An independent, restore-tested copy of your Atlas cluster in your own storage is worth having before the day you need it. Try it on your cluster, or read the MongoDB Atlas backup guide first.
