Answer 1

If you still get same error with --authenticationDatabase admin , than probably your username and password are incorrect. Try adding a user db.createUser() , with appropriate role ( i gave write permission as well)

than run below command : (ignore -h if you are running on local)

 mongodump -h <ip>:<port_number> -d db_name -u newUser -p newPassword -o /home/mongodump/

Hope this helps...

Answer 2

Use signle Quotation around password. if you are using any special character in your password. That will solve your issue. Use following command.

mongodump -d database_name -u userName -p 'password' --out directory_name

Answer 3

mongodump   --authenticationDatabase admin -uroot -pyourpassword

here root is username and yourpassword is your password.

This command will backup/dump all database back-up in current directory.

Answer 4

userAdminAnyDatabase is not enough to do mongodump on all the dbs that's why you are getting this error. You will need a super user that has:

userAdminAnyDatabase
readWriteAnyDatabase
clusterAdmin

privileges to run mongodump on all dbs.

OR you just need 'backup' privilege

db.grantRolesToUser('username', [{
  role: 'backup',
  db: 'name of ur authentication db'
}])

Answer 5

for dump and restore

mongodump --db nameDatabase --username userName --password password --authenticationDatabase admin --out mongodb\
mongorestore --db nameDatabase --username userName --password password --authenticationDatabase admin <path backup> --drop

Answer 6

In my case, mongodump was not correctly processing the password. The solution was to escape the password literal.

This did not work:

mongodump -p my$password -o <output directory>

This did work:

mongodump -p 'my$password' -o <output directory>
