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)
  • mongodump --db=test --collection=records
  • mongodump --dumpDbUsersAndRoles -d YOUR_DB -o /outputpaht/directory/

Sharded Clusters[edit]

Backups created with mongodump do not maintain the atomicity guarantees of transactions across shards
