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?

it's not the recommended way but it's how I've been doing.

you format the new drives and just cp -a -x from the running os to the destination, update the destination fstab, then treat the new drives as an os with a broken boot and continue from there.

Don't cp, use rsync!

@CAPSLOCKFTW @anonono of I rsymc an entire drive, does it preserve all attributed and partitions, or does it just sync a particular file system.

You can only rsync a file system, you have to do the partioning beforehand. It does preserve all attributes though, if you use the right flags.
