mongodump[1] reads data from a MongoDB database and creates high fidelity BSON files which the mongorestore tool can use to populate a MongoDB database. mongodump provides the --oplog option to include in its output oplog entries that occur during the mongodump operation



Database backup:

  • mongodump --archive=test.20150715.archive --db your_db_name (Use: show dbs to view available DBs)
