I’m not quite understanding aptik- is it a backup program like timeshift? Could timeshift be used to restore setting to a new upgrade Linux system (like going from say 19 to 20?) Is Ltik only for reinstalling the same os version? Or can it reinstall all your settings onto a new upgraded version of the same or?
Aptik is not a backup program like CloneZilla. Its purpose is to be able to completely duplicate your complete Linux system over to a new fresh install. I think it only works with Ubuntu based Linux, but I might be wrong. It could be Linux Lite, or Linux Mint Xfce or any other Ubuntu based distro. With the system you want to port over, you make a Aptik backup on an external drive. Then only on a fresh install, you do a restore from the external drive. Aptik install all of the software, settings and personal files on the new fresh install. When finished the new system looks just like the original. It includes everything. For example Thunderbird is complete with all the emails and address book. One can do a CloneZilla backup and restore, but it brings over all the junk that you do not use and will only do the install on a HD that the same size or larger. Aptik will install the system on a smaller HD if there is sufficient room. The interesting part is that when you use the terminal to access the Aptik image file, it also installs the Aptik program itself. I have a number of extra SSD's and like to try new things. I can duplicate my system this way on a new SSD and experiment without worrying if I am going to crash my Base computer.
