Is it possible to restore disk image to a different size hard disk
Solution 1
Sure you can. It's not the best way, but you can do it. dd will not auto expand the partitions to fill up the extra disk space. You can use gparted to resize the partitions after you restore. I use gparted on an Ubuntu install/boot/live cd since I always have a disk with me anyway.
Solution 2
Yes, it will work. But ideally you'd be using partimage
or something more intelligent (including perhaps gparted
) to make the image/clone the disk anyway. Perhaps a Parted Magic live CD/USB?

recently I made a backup 120 GB disk image using dd:
dd if=/dev/sda of=backup.img
Now I have a new 320 GB hard disk and want to restore that backup image to that new disk. Will running
dd if=backup.img of=/dev/sdb
do what I want? Will I be able to use remaining 200 GB of new disk?
(/dev/sda - old 120 GB disk, /dev/sdb - new 320 GB disk, backup.img - image file of 120 GB disk)

SiXoS about 13 yearsExperiment with blocksize (bs=) for faster write speed. Try 1M, 4M, 8M and possibly higher.
