I have linux installed on this laptop. It has 320G HD. I want to experiment something and for that i will have to format my hard disk. I have got a spare 500G USB External Drive. Can someone suggest me a backup method with which i could take a complete backup of current state of the system and later restore it without any issues?
I myself have two options in mind:
Here is my fstab
Filesystem Type Size Used Avail Use% Mounted on /dev/sda7 ext3 19G 12G 6.0G 67% / /dev/sda6 ext2 2.3G 261M 2.0G 12% /tmp /dev/sda2 ext2 89M 45M 40M 54% /boot /dev/sda5 reiserfs 4.9G 614M 4.3G 13% /var /dev/sda8 ext4 264G 133G 132G 51% /home
