Thanks for your answer. I read the wiki page and followed the guide. This is
precisely what I did:
- saved the marking list from Synaptic;
- cloned the /var/cache/apt folder which should contain the .deb packages
(although I found nothing in it, perhaps because I always use autoclean? Will
the marking list still work when restoring even if there are no .deb's? Even
having to download them again would be fine);
- used deja-dup to clone just the home folder, as default;
Is it all? Or am I missing something? The things I care most are the packages
I've installed during these months and the configurations of the apps,
desktop etc.
