Hi again 2g11......
I don't dispute what you are saying at all.....
But, can I propose a reason, with some proof, for my contention regarding no backup of Apps moved to External SD??
My contention is that you are able to restore Apps which have been moved to External SD, for the simple reason that your external SD does not change it's contents, as nothing is written to it by Nandroid restore.....
on external SD is left intact, no back-up, no restore, no change.
As part of Android security, there are asec files in the Phone Internal memory, which are basically sym-links to the Apps which are on External SD.......
these are restored as part of the Nandroid Restore process, so if your external SD has not been corrupted, or destroyed, the Restore will appear to restore those Apps on External SD.
My evidence of no backup of External .android_secure
[I have made a Nandroid backup with CWM recovery, and also used Titanium BU to back-up all Apps+Data]
By use of Titanium Backup Pro ability to extract Apps from Nandroid, I show that an App, my example is Amazon Kindle, is not included in my Nandroid Backup, but it's data is, which is in Internal Phone memory.
See Extract from Nand option and Nandroid Backup used here.

Nandroid Backup used
This App, Amazon Kindle, has been moved to External SD:

Below is a pic, showing the Legend [Symbols] used by TBU:

Now, using the above information, and the fact that Titanium Backup Pro is capable of restoring Apps by extracting from Nandroid, look at the following pic:
Titanium BU showing only Data Backup for Amazon Kindle in Nandroid
As you can see, only Data relating to Amazon Kindle is backed-up.
To check and verify this, I uninstalled Kindle, and attempted to use the Nandroid to restore, as shown above......with no success.
However, as you know, I also had a regular Titanium BU, of Apps+Data, taken at the same time.
With this I restored Amazon Kindle and data without a hitch!!!
My books are still there!!!! Thank God!!!
But, if I was relying on a Nandroid, made with our CWM, to restore this App after a SD card failure or corruption, I would not be able to do it!!!
My advice is, to be sure, always make a back-up of the full contents
of your SD card, by connecting to your PC, and using whatever, e.g. Windows Explorer, with all hidden files and folders shown.....make sure all files with .
are backed up
You never know when that SD card will fail, so "Be Prepared" as they say in the Boy Scouts....dib..dib...dib!!
