How to Keep your core System and personal Data safe while updating to latest Fedora?

[freddie50]

Hi everyone,

Almost everything is in the title!
Which partitions do you keep?
Which partitions do you reformat, while doing a clean install?
Personaly, I never format /var and /home partitions when I update to latest Fedora.
It has been working quite ok up to now, but I was wondering what are the latest best practices on this issue?
Thanks for your comments and advice and keep up the good work!
Cheers,

Personally I backup home to a usb and format all. This go round I forget to check off the format home partition and it miraculously keep all the user data intact. But then again I only setup partitions like:

/
/boot
/home
swap

You should make a backup first ;-)

You might be able to keep /home if it's on a separate partition, but /var has a lot of temporary files you might want to get rid off.
