In appDelegate of your application in the following method

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

Add this code

    NSArray *urlArray = [[NSFileManager defaultManager] URLsForDirectory: NSDocumentDirectory inDomains: NSUserDomainMask];
    NSURL *documentsUrl = [urlArray firstObject];

    NSError *error = nil;
    BOOL success = [documentsUrl setResourceValue: [NSNumber numberWithBool: YES]
                                  forKey: NSURLIsExcludedFromBackupKey error: &error];
    if(!success){
        NSLog(@"Error in disabling %@ from backup %@", [documentsUrl lastPathComponent], error);
    }
