Backup tool for home computer

[Александр Горлов]

Dear All


Could you advise me tool that more suitable for backup data on home
computer under Ubuntu.
This tool should support incremental and full backup.  GUI is
desirable (my wife is not engineer).
I investigated several repositories and found several packages that
proposes backup service. But I cannot select particular tool based on
notes in package description. May be anybody share his/her experience
in this area.
