No the sd card thing is just if you have a partition in it for apps. So the backup you made is perfect. It shows every time when I make one on my phone.

Really, what is happening is that Recovery expects to find that .android_secure folder where the External SD Card normally is for most Android, that is /mnt/sdcard .......

But, things are different on our phone, as our External Card is on /mnt/sdcard/external_sd

AS far as I know, and I am open to correction, there is no back-up of Apps moved to external SD performed by this CWM version.

And, I think that as far as Recovery is concerned, the external SD is on /emmc.....

There is no /sdcard/external_sd/.android_secure as far as recovery is concerned. In recovery, what is /sdcard/external_sd in stock rom, is /emmc - which is the external sd card. I'll see if backing up .android_secure from external sd card can be added.

Not sure if the updated Recovery for CM9 has addressed this issue.....back-up of apps moved to External SD???

I understand you here Irish and I read through your discussion with Arco on this issue,but in reality it appears the CWM never had any problems backing up apps; whether moved to to SD or not.I say this because I have many apps on my SD,yet successfully restored them ALL from my nandroid after flashing new stock ROM.

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.....

the .android_secure 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 folder/files follows...

[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.


TBU Extract from Nand Option



Nandroid Backup used


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


Storage Analyser showing Kindle in /mnt/sdcard/external_sd/.android_secure

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


Titanium Backup Pro Legend


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!!

Irish,looks to me like there's plenty of life in those 57-yr old brain cells yet.I think your explanation completely 'explains' whats going on here.So keeping apps on the 'external' SD also unwittingly protects them from system wipes as long as you make a nandroid...and as long as your SD doesn't fail you!!Thanks Irish!

Just to reiterate:

The best thing to do, and good practice anyway, back up External SD regularly.....maybe when you do other bk-ups.... like Nandroid and TBU.

Make sure that all hidden files and folders are visible ....there is a Windows setting, not sure for Linux or Mac??

This is basically to ensure that the
.android_secure folder is backed up.

The xxxyyy.asec files there are the App files, which are encrypted and "hidden" [asec = android secure]....

and they have sym links to data in Internal Memory.....

Google sure went to a lot of trouble to "protect" App files on removable memory partition.....

Yeah.....I'd say your OK.....

As long as you understand moved Apps on External SD are not backed up.....but that is OK as long as you remember to make a back-up of your SD Card, as outlined in my previous post.....just for your own data security.
