Package org.h2.tools

Class Backup


  • public class Backup
    extends Tool
    Creates a backup of a database. This tool copies all database files. The database must be closed before using this tool. To create a backup while the database is in use, run the BACKUP SQL statement. In an emergency, for example if the application is not responding, creating a backup using the Backup tool is possible by using the quiet mode. However, if the database is changed while the backup is running in quiet mode, the backup could be corrupt.
