How can I dump whole database or individial database using mongodump?

I am trying to backup mongoDB database using mongodump from replicaset. Script I am using works fine to dump db from remote to local. Same script errors out saying authentication failed when I trying to dump from replicaset.

Is there a simple way I can have whole db dump otherwise specific db dump will be preferred.

#!/bin/bash

HOST="mongorep1:27017,mongorep2:27017,mongorep3:27017"
REMOTE_DB="Products"
LOCAL_DB="Products"
USER="AppUser"
PASS="password"

## DUMP THE REMOTE
echo "Dumping '$HOST:$PORT/$REMOTE_DB'..."
mongodump --host $HOST --db $REMOTE_DB -u $USER -p $PASS --out dump/`date +"%m-%d-%y"`

echo "Done."

Thanks

Solution

  • When using replicaset with mongodump, you need to prefix the string pass to --host with the replicaset name. For instance if your replicaset name is myreplicaset_name then it should look like -

    HOST="myreplicaset_name/mongorep1:27017,mongorep2:27017,mongorep3:27017"
