## Initializing an Existing Database Instance

You can use the Database Manager GUI to initialize an existing database on a local or remote computer.

When you initialize a database instance, all the data is deleted.

However, you can keep your database parameters and the configuration of your volumes and backup templates.

### Prerequisites

● You have administrator rights for the database instance. This is always the case if you log on as the first DBM operator

● Database instance on a local computer: You have administrator rights for the computer as an operating system user.

● Database instance on a remotecomputer: You have an operating system user for the remote computer with administrator rights and also the log on as batch job right (for Microsoft Windows operating systems) or a similar right (information on managing operating system users is provided in the documentation for your operating system).
