MongoDB restore warning

Question

I'm following this tutorial to backup and restore a single MongoDB database.

The backup command -

sudo mongodump --db newdb --out /var/backups/mongobackups/`date +"%m-%d-%y"`

The restore command -

sudo mongorestore --db newdb --drop /var/backups/mongobackups/01-20-16/newdb/

Although it works perfectly, MongoDB gives me this warning while restoring the data -

the --db and --collection args should only be used when restoring from a BSON file. Other uses are deprecated and will not exist in the future; use --nsInclude instead

Can someone explain how to remove this warning?

I'm using MongoDB 3.4.1 version.

Answer 1

--nsInclude is new in mongo 3.4.

Instead of older options where db_name and collection_name are given in command line as

mongorestore --db db_name --collection collection_name

namespaces are to be used

mongorestore --nsInclude db_name.collection_name

Similarly

mongorestore --db newdb --drop /var/backups/mongobackups/01-20-16/newdb/

becomes

mongorestore --nsInclude 'newdb.*' --drop /var/backups/mongobackups/01-20-16/
