This article introduces what backup and restore commands are available in mongodb, the content is very detailed, interested friends can refer to, I hope it can be helpful to you.

Backup:

Mongodump-uroot-ppassword-- port=27017-- authenticationDatabase=admin-h hostname-d databasename-o / data/backup/mongodump/

-the address of the server where the h:MongDB is located, for example: 127.0.0.1. Of course, you can also specify the port number: 127.0.0.1 27017.

-d: database instance that needs to be backed up, for example: database_name

-o: where the backup data is stored

Mongo full database recovery

$mongorestore-h host-d database_name-directoryperdb / mg_data/backup/mongodump/database_name

Single collection backup

Mongos > mongoexport-h dbhost-d dbname-c collectionname-f collectionKey-o dbdirectory

-h: address of the server where MongoDB is located

-d: database instance to be restored

-c: collection to be restored

-f: fields to be exported (omitted to all fields)

-o: indicates the name of the exported file

Single collection recovery

Mongos > mongoimport-d dbhost-c collectionname-type csv-headerline-file

-type: indicates the file format to import

-headerline: specify that the first row is not imported, because the first row is the column name

-file: indicates the path of the file to be imported

At the same time, you need to make a physical backup of the library, usually a snapshot

Lvcreate-L10G-s-n data_snapshot / dev/vg01/lv01

After the project team has finished, then remove this snapshot and ok it.

# lvremove / dev/vg01/data_snapshot

If you need to restore, the steps are as follows

Mkdir / snapshort

Mount / dev/datavg01/vg01 / snapshort/

Stop the mongodb, and the backup files of the cp snapshot go to the corresponding data directory of mongo.

Start mongo, and you can.

# mongodb bulk insert data drill Test #
