the bs=64M parameter increases the buffering size so the job runs quicker - 64M seems to be the optimum value for copying typical Windows system disks but you can experiment. This also simply copies disk /partition/file in physical sectors - file system is irrelevant and is IMO far easier than any other method for cloning a disk/fileor partitions.Īfterwards if cloning to a bigger device you can simply add extra partitions or whatever.Īdd the status=progress parameter as shown otherwise you won't get any indication that the job is running until it completes - depending on Disk types and data volumes could be 20 mins or more. To see the disk numbers for x and y or partitions just type lsblk. dev/sdx is the input disk (can also be a file or a partition if you want) /dev/sdy is the output disk / file / partition. Simply sudo (or su) dd if= of= bs=64M status=progress So yeah - isos are possible but more faffing around than it is worth (in my opinion).Īnother great way of backing up a pc is the new ffu method of Kari.Īlso easy for anybody who can boot up any live Linux distro Not only that an iso is pretty space inefficient as it is not compressed like a Macrium Reflect Image Backup. Problem with iso, is it will almost certainly get a custom install.wim > 4 GB and then you need to use another tutorial to create a bootable usb drive. Althpugh making a iso from current installation is doable, it really is easier to make a system image backup using Macrium Reflect Free.
