This is a re-edit, because no one seems to want to answer the actual question.

To simplify: Will a non-root backup save everything? Do I have to log in as root to copy sbin, home, etc to a backup disk?

Thanks for all the answers on logging in as root, but that wasn't the problem.

Complete backup - cloning the whole drive

  • A complete backup can be achieved by cloning the whole drive. You do that with Clonezilla, booted from a CD disk or USB pendrive.

    • either create a cloned copy on a third drive of at least the same size as the original one,

  • or better: create a Clonezilla image, which is a directory containing several files where the big ones are compressed.

Backup all your personal files

  • You can run backup systems, that backup all your personal files more or less automatically with or without root permissions (like suggested by @Panther). See this link,

    help.ubuntu.com/community/BackupYourSystem

It is possible to

  • configure the backup system to backup the directories and files, that you think are most important to backup,

  • you can select incremental backup

  • you can select compression or no compression

  • you can configure when (and how often) you want to run your backup system.

depending on the backup tool that you select.
