  • Is that what you want https://askubuntu.com/q/9135/1051814 ? – AEM May 25 '21 at 13:35
  • I always suggest new install & restore from your normal backup. You do have a backup in case hard drive fails and you then have to do a new install? Backup should include list of installed apps as link in comment above, all of /home and your data if in other partitions. You may want some /etc files but if different hardware not all of it. And if server apps, you want to backup those folders in /, but do not need the rest of /. http://askubuntu.com/questions/545655/backup-your-home-directory-with-rsync-and-skip-useless-folders – oldfred May 25 '21 at 17:26

Using dd to Clone File System from Old Drive to New Drive

  • Create Live Ubuntu USB and Boot it.

  • Plug in Target drive, (must be at least as large as Source drive).

  • Open Gnome-Disks to confirm drive designations, sda, sdb, etc.

  • In Terminal run sudo dd if=/dev/sdx of=/dev/sdy

    Where sdx is the Source drive and sdy is the Target drive. Double check that the Target device designation is correct, one typo can overwrite your OS.

    Some people prefer to add a block size, such as bs=256k, but I do not bother.

    The process may take a long time without showing activity.
