//Database Properties
/******************************************************/
String dbName = “dbName”;
String dbUser = “dbUser”;
String dbPass = “dbPass”;

/***********************************************************/
// Execute Shell Command
/***********************************************************/
String executeCmd = “”;
executeCmd = “mysqldump -u “+dbUser+” -p”+dbPass+” “+dbName+” -r backup.sql”;
}
Process runtimeProcess =Runtime.getRuntime().exec(executeCmd);
int processComplete = runtimeProcess.waitFor();
if(processComplete == 0){

out.println(“Backup taken successfully”);

} else {

out.println(“Could not take mysql backup”);

}

Restore:

/******************************************************/
//Database Properties
/******************************************************/
String dbName = “dbName”;
String dbUser = “dbUser”;
String dbPass = “dbPass”;

/***********************************************************/
// Execute Shell Command
/***********************************************************/
String executeCmd = “”;

executeCmd = new String[]{“/bin/sh”, “-c”, “mysql -u” + dbUser+ ” -p”+dbPass+” ” + dbName+ ” < backup.sql” };

}
Process runtimeProcess =Runtime.getRuntime().exec(executeCmd);
int processComplete = runtimeProcess.waitFor();
if(processComplete == 0){

out.println(“success”);

} else {

out.println(“restore failure”);
