I am a Windows (and occasional Linux) user. For many years now I have had a policy of using Acronis True Image to make an image copy of the system disk of a newly built Windows system. This allows me easily to restore a clean system in the event of a virus or other disaster. From time to time I will restore from this image, update all the relevant software, apply patches, etc. and then make an up-to-date image of the system disk. Is there any similar technique available for Android on a Tablet or 'phone? What happens if you install some piece of software that cannot readily be removed or in some way your system gets corrupted? It will be pretty obvious that I am not at all familiar with Android. However, any Android user to whom I have spoken seems entirely unconcerned about backing up, a few of them copy off photos and perhaps contact lists but other than that, they don't seem to care. The device in question (Samsung Galaxy Note Tablet) includes some reasonably expensive software (Memory-Map OS Explorer 1:25,000). She doesn't want to have to pay for it again if she loses (or somehow corrupts) it. What she would like to do and has asked my advice on is what I described above - make an image of the working system with the desired options loaded. I understand that Google will back up Apps, Contacts and Photos (if you turn on Google photo upload). However, so far as Google capturing her contact details and photos for whatever commercial uses they might dream up is concerned - I suspect that she could certainly live without that happening - although I accept that they will probably do it anyhow Any suggestions?
