In mongodump we can change the behavior of the output. bson will hold the documents (data) for each collection. metadata.json files will hold metadata information such as options, indexes and ns (for the collection namespace) for each of the collection. We will have a BSON file and a JSON file for each collection. Inside the database specific folder we will have two files for each collection in our database. In our case, there would be a sub directory inside called mydb so your new folder structure would look like. Inside you will have a subfolder with the name of the database. If it’s the same, then you would change the -authenticationDatabase flag to the correct database or in URI format the authSource querystring option to the correct database.Įither of these methods dumps the whole database into a dump directory (named dump by default), in the current working directory you ran the command in. This is assuming that the authentication db (which stores your database user) is different than the database that you would like to dump. Or with a Mongo URI format: mongodump -uri="mongodb://myuser: :27107/mydb?ssl=false&authSource=admin To export a database called mydb from your localhost with mongoexport you can use: mongodump -user=myuser -db=mydb -password=somepass -authenticationDatabase=admin You can connect to your mongo database using either: -uri with a correct formatted uri string OR with the -user, -db and -password flag options but you cannot use a combination of both.
#Leanote mongodb dump restore how to
We can look at a few of the command line options for the mongodump utility and walk through examples of how to use it. Using mongodump you can later restore your database with the mongorestore utility. Say for instance, you are scheduling backups of your database on a daily basis using a cron job method. Mongodump is typically used for a backup strategy. can export data from standalone, replica set, and sharded cluster deployments. mongodump can export data from either mongod or mongos instances i.e. Mongodump is a utility for creating a binary export of the contents of a database. Here we will discuss how to use both methods and when one method might work better than the other. If you have worked with MongoDB you may know that there are two different ways to export and import a Mongo database: mongodump/mongorestore and mongoexport/mongoimport.
