Personally, when I get a new SSD I:
nodev,nosuid,noexec set)/home across, and parts of /etc.Same thing you suggested, plus a btrfs scrub to check integrity when finished. I suspect btrfs provides a more elegant mechanism for this, which I have been too lazy to look up.
I could never reinstall ... I end up customizing so extensively that a few years ago, I centralized all of my customizations in a VM image that I clone if I do need a fresh install.
I always use dd or ddrescue. Takes 20min to open the computer, connect the drives, boot from usb, copy everything and you'd be done. Also super easy. Just pay a lot of attention before hitting enter. One small mistake and you copy it the wrong way around. Or overwrite your old drive in some other way.
Clonezilla Live USB ftw
I usually use Clonezilla and have it verify the data after cloning. It works for local drives, but it can also clone a drive over the network by running it on both the source and destination system, which is very useful for remote servers (eg moving a VPS to a different location).
Adjust partition size if neccessary, then cp /dev/sda /dev/sdb.
btrfs device add /dev/newdrive /
btrfs device remove /dev/olddrive
For my personal workstation, it's such a rare thing I always use that an excuse to start from scratch again. If it's like a business system or something, usually build a new system and migrate data and services to it gradually.
I so rarely do in-place upgrades of system drives unless it's a recovery or something.
True. Starting with a fresh install can be more of a performance boost than buying a new drive. Add them together though and your computer is going to feel like future tech. I'd also just reinstall, unless its a server or a pain to rebuild.
Pretty much this. I’d copy anything I want to keep onto a temporary drive, (cloud storage, a USB drive, second SSD, etc), then use it as an excuse to refresh my install. Then just copy everything from that temporary storage after my new install is finished.
Honestly dd is perfect. Like you say, shrink the partition down first, DD to the new disc, swap discs. That's it.
Reinstalling because I use ZFS.
Anything important is already stored elsewhere, so I just install clean.
Pretty much this... although I usually have at least a few moments of paranoia thinking about what I might be about to lose.
disk destroyer? I prefer just formatting and rsync-ing things. Unless I care about preserving metadata.
rsync -a ftw
I usually use rsync -avHXS --numeric-ids --progress --delete
Last time I did this I used btrfs.
Add the new drive to the system, create partitions, add the new volume and then remove the old one, btrfs moves all the blocks to the new drive.
The ESP partition is small enough and FAT- enough to just use cp.
Gparted works great as well, just umount drive and copy
rsync
Out of curiosity, what are you doing that the difference between the two is woth that effort? Or is the pcie3 drive bottom of the barrel maybe?
Yeah, exactly the latter. I noticed the other day that the thin copper layer that sits across the top of this drive had just popped off!
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.
