Hey ya! I recently introduced a friend to Linux. His choice was POP!_OS and he's very happy so far. As a good guide, I told him, that if he tinkers with it, he'll break it eventually, which happens to every good Linux-User once in a while For that I gave him a script I wrote that uses dd to make a backup and pipe it to 7z/gzip. However, he's in a little different situation. While I have a 250GB SSD, that backs up on sundays in the background, he's got a 2TB NVME which takes a huge amount of time. So: Is there a good alternative to dd when it comes to backing up large drives? Let me know, thanks in advance! Arokan

You can compress the file system directly without affecting the whole drive. This works best when storage under 2TB is used. For higher usage, performance will be similar for both methods.

I understand two methods I’m familiar with: rsync and snapshots. Rsync copies files one-by-one for a specific folder, often used to back up your home directory—so when you reinstall, everything stays intact. Snapshots need a particular filesystem like ZFS or BtrFS, and tools such as Timeshift or Snapper can create and restore them. They use minimal space and let you boot from GRUB for quick recovery. Snapper has helped me more than once, and setting both up is straightforward.
