How to export all collections in MongoDB?

by

For lazy people, use mongodump, it’s faster:

mongodump -d <database_name> -o <directory_backup>

And to “restore/import” it (from directory_backup/dump/):

mongorestore -d <database_name> <directory_backup>

This way, you don’t need to deal with all collections individually. Just specify the database.

Note that I would recommend against using mongodump/mongorestore for big data storages. It is very slow and once you get past 10/20GB of data it can take hours to restore.
