If you have installed ios version prior then ios5 then no data will backup to cloud. Becouse i-cloud comes with ios5.

In ios5.0 you can stop your backup with following function

(BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL {
    NSLog(@"in add skipBackUpAtrribute method.......");
    const char* filePath = [[URL path] fileSystemRepresentation];

    const char* attrName = "com.apple.MobileBackup";
    u_int8_t attrValue = 1;

    int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
    return result == 0;
}
