SYSCS_UTIL.SYSCS_BACKUP_DATABASE system procedure

See "Using the backup procedures to perform an online backup" in the Derby Server and Administration Guide for more information on using this procedure.

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 "Configuring user authentication" and "Configuring user authorization" in the Derby Security 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:
