What backup and restore commands are available in mongodb

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 #
