I want to backup my whole system (debian sarge) using tar archives. As far as I know, I can just backup my data using
tar cfzvp bootbackup.tar.gz /boot
to backup my whole boot folder. System folders like /proc or /sys, as well as /tmp, need not be backed up. I will also backup my master boot record and partition table. (I'll do all this backup stuff using a live CD, not on a running system)
However, I'm not perfectly sure how tar handles symbolic links. If I understabd the man page correctly, it normally just archives a link which poits to the original file. That should be OK when I archive the entire disk, right?
Will this approach allow me to fully restore my system later on?
