## recover_check

### Use

You check whether the Database Manager can properly access the specified data carrier and read the data there. You can use this DBM command to check if access to a backup tool is functioning, for example.

This DBM command is executed irrespective of the functions running on the database. However, it might cause a temporary loss of performance in the database instance.

The backup specified is just checked, not restored.

### Prerequisites

● You have the server authorization Backup.

● You have opened a service session (see: service_connect).
