How to unimage android?

Question

Android

Good afternoon.
Everywhere it is advised to shoot an image of a partition in Android via dd, having previously recognized the blocks. However, there is a /by-name folder. Can you take a picture from there? And also restore?
It’s impossible to simply mount / data in TWRP due to encryption and its block cannot be recognized in any way.

Answer 1

if you need the contents of the folder, then you can copy it while the android is running. and also pour it back. Problems begin at a backup of active files.
only you first decide what you need: the image of the partition or the contents of a specific folder on this partition??
these are somewhat different things.
