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.

    Boot from a USB drive, then use DD to copy the entire disk over and resize the partitions if necessary.

      What if I want to clone an installation from a 2 TB drive (that is less than half full) to a 1 TB drive? Would I have to resize then dd?

      dd + partition resize is a bit overkill. You can use cp -ax to copy at file level instead of disk level. Or, if you really want to clone the partition, using cat is faster than dd.

      dd can be fast if you experiment with and pick the right block size, but ofc doing that would take extra time.

        You have to create and configure partitions and file systems if you do it at the file level. It also may not work if you’re using disk encryption. There’s a greater chance of having functional differences due to permissions, ownership, linking, etc doing things at the file level - though it SHOULD be fine but why bother if block device level is viable.

        Did not know cat could be used that way.

    One argument against using DD is that sometimes the optimized default flags for FS creation change between kernel releases so its nice to take the opportunity when getting a new drive to reformat partitions. In addition to this, dd is slow if you haven’t completely filled up the partition because it doesn’t attempt to use fs metadata to seek sparse data on disk and instead copies all bytes of the partition. (Completely unnecessary and just causes extra wear on solid state medium)

    I use rsync instead of cp so I get verbose messages, hash checks, and resume functionality during large copies. https://wiki.archlinux.org/title/Rsync#File_system_cloning

    I would go with clonezilla or dd. Always making a backup first. Do you have a tirth drive for it?

    Don’t use Timeshift. Copy what files you need from the old drive to the new one with the new system running.

    If all you’re doing is moving drive to new system, move it and boot that sucker. Linux has all the drivers in the kernel and will boot on anything

    However that’s not what you’re doing. For changing drives, if you can’t just clone your old Linux drive(can’t because it’s dual boot) then just do a clean reinstall and copy over what you need. A hassle, maybe, but you’ll avoid merging things from the old system and the new.

    As a general rule of thumb, if you move your entire home folder or Timeshift, it’ll restore a bunch of stuff you either don’t have installed on the new system or it’ll overwrite something you need. Best to do it clean.

    Also I wouldn’t bother with the Raid 0 personally because it just introduces slightly less performance for basically no benefit in your case. So you can lose an SSD and still boot - is that really a priority when you could always boot USB or windows for recovery? I’d map the second to like /mnt/steam/ and put your games there for a dedicated Steam drive for increased performance, and you can always reinstall all that.
