I do wonder what the purpose of this is. Are you planning to use it for recovering if a disk/server/site is lost? The problem you may have is getting something running so that you can execute the restore and if it's dissimilar hardware it still may not work.


What is the requirement for this backup, i.e. what are you planning to restore to?



Kind regards,

I was asking the question only for my knowledge only..i like to dig deep and investigate.
I usually use tar to backup my Debian Lenny server..but that day I was surprised to see the syntax with the dot..I thought it was a typing error. I tried omitting the dot...it gives an error.

The following is the command I use for backup:

Code:
tar -cvpf /BACKUP/backup-PROD.tar / --exclude=/proc --exclude=/lost+found --exclude=/mnt --exclude=/sys --exclude=/dev --exclude=/BACKUP --exclude=/media

The restore was done on a PC, I boot with a live CD, wipe everything on the /
, then UNTAR everything there.

For the PC to successfully boot:
1. MBR/GRUB must be properly configured
2. udev > persistent rules - must remove the MAC addresses
3. in /boot/grub directory necessary changes needs to be done if you are changing from a raid 1 to a non-raid configuration.

The restore was a good experience for me and worked without any issues
