Or if you plan on keeping the same partition layout, you can simply not overwrite the /home partition to keep it intact. You'll still want to backup the passwd, shadow and group files in /etc as pointed out. You'll also want to make a backup of /home just in case anything goes wrong, but if you want to take that approach, it'll save you the time in actually placing the /home directory contents back on the server, after the reinstall, and if untouched, everything should be there.

thank you for your reply

Save your /var/log/* if you care about your logs.
