Exporting from MongoDB
To export the database, simply tell
mongodump
which
database (or collection) you want to export, and where to export it to.
Mine was the pets database, so my command looks like this:
mongodump -d pets -o petsbackup
|
This dumps the
pets
database into the
petsbackup
directory. Take a look at what we have in that directory now:
pets
├── animals.bson
└── system.indexes.bson
0 directories, 2 files
The only collection in my
pets
database is the
animals
collection, however you'll see a
.bson
file for each collection in your database, plus the system indexes
collection. It is up to you whether you want to take individual
collections, or a whole database, but bear in mind that your choice will
dictate whether you get information about indexes etc when you import
the data elsewhere.
Importing to MongoDB
To import, simply use the
mongorestore
command, which accepts either a single
.bson
file representing a collection, or a directory containing multiple files. Here's my example:
mongorestore -d pets /path/to/pets
|
You can specify any database name and path to files you like, so for
taking backups or restoring additional copies of a database, this can be
really handy. The mongo commands are well-documented and I found them
easy to work with - hopefully this helps you work with them too!
