I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The best that I'm aware of is if you can install a custom recovery (like TWRP or CWM), then when you boot into the recovery you can make a Nandroid backup of everything.

I need something like a "cloner" to get an image of the full disk.
Recovery tools only backups or recovery specific things like photos, contacts, etc.
The Nandroid backup is for the entire system, it doesn't do just contacts or photos, etc.  It doesn't do a block-level backup but I think it's the closest you can come on an Android system.

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Well actually you can select which partitions you want to make a backup of.

If you want the ability to screw up your phone to the point where it won't boot and then recover to a working backup, this is your option.

mm  I have searched for it but probably the link I find ( is not the one you mention, can you please post the correct links?

Yes, that's the one for TWRP.  You'd download the one for your device.

The most difficult part may be actually loading it on your phone.  The procedures and requirements can vary from one phone to the next and also depend on carrier, so I can't help with specifics.  Essentially you have to have an unlocked bootloader, and at that point you can run a command like
flashboot flash recovery recovery.img
The page for your device should have the information to flash the recovery, but it'll likely take you some research to find what is needed to unlock the bootloader on your phone.

I would like to get the image of the operating system hard disk of the phone and then load it to a Virtual Machine like vmWare or NowSecure Forensic.
A Nandroid backup is the best you're going to get (unless there's some commercial forensic software out there I'm not aware of).

Loading it into a VM is an entirely different question and I couldn't help with that.

mmm that means I should root my phone so I cant do that, it is a corporate phone.
Jackie ManIT ManagerCommented:
The system files of Android OS are system protected and there is no possible means of "cloning" without rooting the phone.

Titanium Backup can backup all files (including the system files)  and root is a MUST before you can copy them.

NowSecure Forensic can root the phone running Android 4.3 or above via Android ADB Backup Extraction.

Not the answer I was expecting but anyways, it clarifies the scene.
Can you tell me why you gave a "C" grade?  The information looks complete, even if it's not what you were expecting or wanted to hear.
José PerezAuthor Commented:
Do I have to evaluate the grade based on your answers or on what was required?
Please reference

In general a "C" should only be given when an answer addresses only part of the question, and you've asked for additional clarification.  Answers such as "that's not possible", "that's not a good approach, but this is" can be perfectly acceptable answers.
