Guide to system backup
Hello guys! How are you? I would like to know if someone can get me, if possible, any link to a good and complete system backup manual, that explains how to use the 'tar' command and some backup hints and strategies. I usually backup my system giving the command:
tar -zcvf backup.tar.gz /
And so I move this file to another partition where I've made a very minimal Linux installation. If anything happens, I just boot from my floppy disk this partition, acess my full Linux partition and give the tar -zxvf command. But what I can see is that although it works, I waste so much HD space when I do that, even after deleting the backup file from my full linux partition, I don't know why. I usually see in the examples about tar -xvf people just backuping their home directories. So i would like to know if anyone knows any url that gives a really good guide about what is the best way to backup the system.
Thanks so much for your attention.
