How to backup (and restore) Persistent Kali Live USB
I'm just getting started with Kali, and for now I've chosen to run it from a Live USB which ive set up as persistent - no problems. Note that this is NOT encrypted.
My question is: How can I periodically (manually) backup the contents of the Live UBS stick? Is there a way to do a byte-for-byte backup of the whole stick ? or should I just intend to backup the contents of the 'persistence' partition ie not the ? can this be as simple as an archive of that partition (tar?)
Of course I would wish to restore the backup if the need arises - if I make a new live USB how can I be confident that the restored 'persistence' volume would work with that new stick?
BTW - My laptop has ubuntu installed, so I'd be backing up/restoring to that -- I guess that makes this a Linux question, but since my concern is the integrity of the Kali persistence volume - hence asking the question on a Kali forum ;)
thanks all.
