From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Best practices for transferring an existing Linux installation from one drive to another? (lemmy.world)

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?

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.
