Hot Backup

Percona Server for MongoDB includes an integrated open-source hot backup system for the default WiredTiger and alternative MongoRocks storage engine. It creates a physical data backup on a running server without notable performance and operating degradation.

To take a hot backup of the database in your current dbpath, run the createBackup command as administrator on the admin database and specify the backup directory.

> use admin
switched to db admin
> db.runCommand({createBackup: 1, backupDir: "/my/backup/data/path"})
{ "ok" : 1 }

If the backup was successful, you should receive an { "ok" : 1 } object. If there was an error, you will receive a failing ok status with the error message, for example:

> db.runCommand({createBackup: 1, backupDir: ""})
{ "ok" : 0, "errmsg" : "Destination path must be absolute" }
