[Discuss] Backing up the entire software installation

[nancythewriter7 at gmail.com (Nancy Allison)]

Hi, all.

I have Fedora 28 and lots of programs installed. I use a backup for my
files, but I dread the day I have to start with a new computer and
reinstall all my programs.

Is it possible to create a copy of everything, my Fedora 28 operating
system, all the programs, all the nifty Firefox plug-ins, all my Favorites
-- everything? So if this hard drive died and I needed to get a new laptop,
I could copy over the entire contents of this computer without having to
recreate it?

If so, how would I do that?

If I can't do that, how can I at least generate some kind of list of
everything I have installed so I don't have to rack my brains trying to
remember everything I had on this box?

Thanks.
