using mongodump with mongodb atlas

Question

For some reason I cant connect to atlas using the connection string but instead of using mongo use mongodump. I have tried all type of string.

So its either I get "positional argument not allowed" when the I just replace mongo with mongodump or I get

"failed: error connecting to db: no reachable servers" when I change the host from "mongo://replset1:27017,replset2:27017,replset3:271017/test?replicaSet=replicaSetName" to --host replicaSetName/replset1:27017,replset:27017,replset3:27017

Anyone know what the problem is here.

Rememeber I can make connections using mongo client.

Answer 1

Currently mongoDB Atlas has a copy and paste option for "mongodump" in the "Command Line Tools" section of your cluster. First login to your mongoDB Atlas cluster. Next, on the left side of the screen make sure "Clusters" is chosen. Then, you'll see two options "Overview" and "Security", make sure "Overview" is chosen. Directly below "Overview" you should see "Sandbox". Under "Sandbox" you should see the name of your cluster which is a clickable link, click it. You'll then see a number of optional links to click, click "Command Line Tools". Here you'll see the copy and paste option for "mongodump".

Answer 2

In my case I finally got it this way:

# mongodump -d DB-NAME -u SUPERUSER -p "SUPERUSER-PASSWORD" -o "PATH/TO/DUMP/FOLDER" --authenticationDatabase AUTH-DB --ssl --port 27017 -h "REPLICA-SET-NAME/CLUSTER-SHARD-00-00,CLUSTER-SHARD-00-01,CLUSTER-SHARD-00-02"

Where:

• DB-NAME: Name of the database to backup
• SUPERUSER: User name with all privileges, the one you got creating the cluster
• SUPERUSER-PASSWORD: Self explanatory ;)
• PATH/TO/DUMP/FOLDER: Where you want to save the dump
• AUTH-DB: The database for authentication, by default is called "admin"
• REPLICA-SET-NAME: The name of the replica set in the form "cluster-name-shard-0"
• CLUSTER-SHARD: Name of the cluster shards IE: "cluster-name-shard-00-00-kb2rd.mongodb.net, cluster-name-shard-00-01-kb2rd.mongodb.net, cluster-name-shard-00-02-kb2rd.mongodb.net"
