Backing Up and Restoring Databases

NuoDB provides several ways for you to make a copy of a database that you can use as a backup:

If you copied current state by means of offline backup or online backup then you can restore the data by invoking the NuoDB Manager restore database command on the database copy. This operation creates a new database from the backup copy. See Using Copies of Current State to Restore Data.

If you used online snapshot backup then you invoke the NuoDB Check utility (nuochk) to restore data to a snapshot. This operation creates an archive that you can use to start a storage manager or a snapshot storage manager. See Using Snapshots to Restore Data.

In this release, the following are preview features:

Caution: NuoDB encourages you to use preview features in your development projects. However, the use of preview features in production is not supported.
