I have a pre-fail drive, and while I'm waiting for replacement I am trying to do full back up to two smaller drives. Given that drive is 3TG and ones I have are 1.5 and 2TB, is this a correct way to do the backup?dd if=/dev/sda of=/mnt/sda-1G-1270 bs=1G count=1270then plug in 2nd drive, mount it, and do:dd if=/dev/sda of=/mnt/sda-1G-rest bs=1G skip=1270and to recover:dd if=/mnt/sda-1G-1270 of=/dev/sda bs=1G count=1270dd if=/mnt/sda-1G-rest of=/dev/sda bs=1G seek=1270will that work?..
Is this a correct way to back up one big drive to two smaller ones?
backup;dd
