Mongodb 3.6.1 on Windows 10

I have taken dumps from multiple databases and placed all in a single folder. I am trying to run mongorestore so that it restores only those collections in a single database:

mongorestore -v -d TargetDb1 --nsInclude 'TargetDb1.*' --drop .

The problem is that mongorestore is loading all collections from all databases into TargetDb1. I was expecting --nsInclude to select only those collections that have TargetDb1 in its namespace. Otherwise, having a namespace is rather pointless.

Got any suggestions what I'm doing wrong?

Hi Mike,

When you created a data export using mongodump the output (default) would be in a directory structure as below :

dump/
    database1/
        collection1.bson
        collection1.metadata.json
        collection2.bson
        collection2.metadata.json
        ...
    database2/
        collection3.bson
        collection3.metadata.json
        collection4.bson
        collection5.metadata.json
        ...
    ...

Then, you can restore using mongorestore‘s option —nsInclude to specify which collections to restore. For example, by executing below:

mongorestore -v --nsInclude "database1.*" --drop dump/

The nsInclude statement specifies to only restore content in the database1 database. For your use case, that would be --nsInclude 'TargetDb1.*'.
