mongodump against access control

I was trying mongodump to backup some dbs in mongodb and I have auth enabled in my mongodb.

I have one super user with role: "root" and db: "admin" and one with dbOwner for a specific db abc.

I tried this following command

mongodump --username admin --password "xyz" --authenticationDatabase admin


error - Failed: error dumping metadata: error creating directory for metadata file dump/abc: mkdir dump: permission denied

may be I need to use the credentials of the dbOwner but I thought being the super user one can do that.

Pls tell me how to use these two credentials in mongodump command.

The error comes from local filesystem, not from mongo. The user who runs mongodump command has no permission to create a directory dump in current directory. - Alex Blex

You just follow:

Syntax:

mongodump -d <databasename> -o <target directory>

Example:

mongodump -d user -o ./desktop/foldername.

Where: the user is a collection name and -o is an output file and folder name is an where to store in the file.

I had the same issue and I found this answer posted by kallko on Gihtub which helps me.

So to resolve it, you need to add a sudo just before the command and that's it. It works for me.

Hope it helps !
