Hello,   Unfortunately, I can't recommend any back up software which is suitable for you, as we don't have any information or documentation to support. Though, it's recommended to do backup at file level, as the OS verifies if the file is valid before it's being transferred out.    You can refer to this link: [URL] to try recover the array, but you should recreate the array after the file level back up.
