Hello!

I am looking for a simple backup solution which serves two purposes.
1. Backing up data of defined directories (e.g. ~/Downloads, /media/NAS-Drive)
2. Backing up data of relevant system/application settings (KDE, Iceweasel, etc.)
3. Save Restoring in case sth. goes down the gutter

I just recently started to use Linux more intensely, so I have a few newbie questions:

A) regarding system settings, what folders will be useful to backup?
/etc is the most obvious one. But are there other important folders like /var or /usr which should be added?

B) What backup tool can be recommended?
I tried a bit with simple tarring and copying of files in anacron scheduler, but I would like to have something simple with a GUI, ideally integrated in KDE.
With a overview of what and when things will be backuped. With easy adding and changing targets.

I asked Mr. Google, but I could not find anything consistent and actual, and I hesitate to try out everything out there.
Any suggestions to narrow down the candidates?

Thanks a lot

I only bother with /etc/ as I don't have a lot of special software installed (/usr) and logs are not of the greatest interest (/var) but that really depends on your situation/requirements.

I remember luckybackup being a reasonable piece of QT-software although the name does not inspire confidence

Exactly what I was looking for. Thanks!
