1. Cold backup and recovery-create a copy of the data file (if you stop the MongoDB server), that is, directly copy www.2cto.com MongoDB stores all the data in the data directory. The default is / data/db/ (C:\ data\ db\ under Windows). When starting MongoDB, you can also use-- dbpath to specify the data storage directory we set. Backup MongoDB data: simply create a copy of the data storage directory, directly copy a copy. Restore MongoDB data: use-- dbpath to specify the location of the copy of the data storage directory when MongoDB starts.

It is risky to directly copy when the server is running. It is possible that the data has been destroyed when the copy comes out. To create a copy of the data directory in this way, under the premise of shutting down the MongoDB server, what is stored in the data directory is to close the snapshot of the data at that moment. Before the server restarts, you can copy the directory as a backup.

2. Hot backup and recovery-- mongodump and mongorestore tools included in the MongoDB bin directory

Backup

/ usr/local/mongodb/bin/mongodump-d user_db-o / data/bak/0701_user_db

Restore

/ usr/local/mongodb/bin/mongorestore-d new_user_db-drop / data/bak/0701_user_db/user_db
