Currently, my desktop computer has two storage devices attached: one 1TB NVME SSD, which has both Windows 10 and Linux Mint 21.2 installed on it (Each OS getting ~ 500 GB), and a 1TB SATA hard drive mostly used for Timeshift backups of the Linux Mint partition (Including my Home folder, for the record).
Later today I’m expecting to receive two more 1TB SSDs. When I’ve finished the upgrade process, I’d like to have my Linux Mint installation transferred to a RAID 1 array comprised of the two new drives and expand the Windows 10 partition to take up the whole existing SSD.
My current plan for doing this is to use my existing installation USB drive to install a fresh Linux Mint 21.1 installation on the two new drives, then use Timeshift to ‘restore’ my most recent backup from the existing installation. Is there a better way of going about this that I’m not already aware of?
Clonezilla local disk to local disk has worked well for me. It also automatically fixes GRUB and fstab so you don’t need to worry about those things. Boot params and such can get a bit hairy.
Fixing grub and fstab makes it very newbie friendly compared to other methods.
Clonezilla is the answer. It has all the options, and just works right the first time
