SYSCS_UTIL.SYSCS_BACKUP_DATABASE system procedure

The SYSCS_UTIL.SYSCS_BACKUP_DATABASE system procedure backs up the database to a specified backup directory.

Syntax

SYSCS_UTIL.SYSCS_BACKUP_DATABASE(IN BACKUPDIR VARCHAR()) 

No result is returned from the procedure.

BACKUPDIR
An input argument of type VARCHAR(32672) that specifies the path to a directory, where the backup should be stored. Relative paths are resolved based on the current user directory, user.dir, of the JVM where the database backup is occurring. Relative paths are not resolved based on the derby home directory. To avoid confusion, use the absolute path.

Execute privileges

If authentication and SQL authorization are both enabled, only the database owner has execute privileges on this procedure by default. See "Enabling user authentication" and "Setting the SQL standard authorization mode" in the Java DB Developer's Guide for more information. The database owner can grant access to other users.

CallableStatement cs = conn.prepareCall
("CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE(?)");
cs.setString(1, "c:/backupdir");
cs.execute();
cs.close();

SQL example

The following example backs up the database to the c:/backupdir directory:
