Backup Ubuntu 19.10, upgrade to Ubuntu 20.04 and restore (if broken)

  • 772

I'm pretty new in Ubuntu and I want to upgrade my Ubuntu 19.10 system to Ubuntu 20.04 (not the beta, I will do it when the full version is out) and to be safe I would do a backup of the entire system. How can I do it? I want not only to backup /home, but also every file I have in /opt, /bin, and everywhere else.

Is there any tool to do the full backup? If I will need to restore my backup in the new system, how can I do it?

Any kind of help would be appreciated, thank you.

EDIT:

  • Now I'm using deja backup (the default one in Ubuntu). Is that tool
    good to just backup everything (I mean, everything, including
    programs) and then restore it (if needed)?
  • If I backup the entire system and then I restore it on Ubuntu 20.04, will it break something?
  • If I snapshot my entire system and then restore it on Ubuntu 20.04, will it break
    something?
  • If I do a bootable USB of my entire system and then boot
    my pc with it, will I have everything (including /opt and others)?

    I use and love Clonezilla to make and restore images of system disks. It's free to download and burn to CD/DVD or make a bootable USB stick.

    It's from Taiwan, so the English is a bit lumpy, but correct.

    I have used it to migrate several dual-boot systems from spinning disk to SSD and have never has a problem.
