+Output Format
+~~~~~~~~~~~~~
+
+:binary:`~bin.mongorestore` and :binary:`~bin.mongodump` can output data
+to an archive file, which is a single-file alternative to multiple BSON
+files. Archive files are special-purpose formats that support
+non-contiguous file writes. They enable concurrent backups from MongoDB,
+as well as restores to MongoDB. Using archive files optimizes disk I/O
+while backup and restore operations execute. 
+
+You can also output archive files to the standard output (``stdout``).
+Writing to the standard output allows for data migration over networks,
+reduced disk I/O footprint, and concurrency gains in both the MongoDB
+tools and your storage engine. 
+
+For more information on archive files, see the
+:option:`--archive <mongodump --archive>` option.
