It's just been days since I started using Ubuntu on my PC and I'm doing my best to keep it updated at all times via 'Update Manager'. But what I've noticed is that if I update today the next day when I log in there is a new set of updates waiting for me.
I want to keep these updates as a backup so I don't have to download the updates all over again if I am forced to freshly install Ubuntu. So what do I Backup?
NOTE: I'm doing this following some random website I visited while surfing the net. This is what I'm doing (in Terminal) to backup files
sudo su cd / tar cvpjf backup.tar.bz2 --exclude=/proc --exclude=/lost+found --exclude=/backup.tar.bz2 --exclude=/mnt --exclude=/sys /
and to restore it I'm using this (after I put
backup.taz.bz2 in the root location)
sudo su cd / tar xvpfj backup.tar.bz2 -C /
but I'm not sure if this backups the updates...does it?
