[ale] Backup questions -- what to back up?

[Derek Atkins]

Hi,

I'm working on configuring some backups via rdiff-backup, and I've got
some style questions.  My main question is: do you back up /bin,
/usr/bin, /lib, /usr/lib, and other "system" directories?  Or do you
only backup /root, /etc, /var, and select areas, and keep a package list
of the installed packages?

If you do backup the system directories (/bin, etc), what's the best way
to restore the system?  I'm thinking disaster recovery, not "oops, I
deleted a file and need it back"?

Thanks for your guidance,
