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.

OS Backup - what should and what should not be backup'd? (lemmy.kde.social)

Hello there! Here's the thing: I got some old HDD for my Debian home server, and now that I have plenty of disk space I want to keep a backup of the OS, so that if something accidentally breaks (either SW or HW) I can quickly fix it.

now the question is: which directory should I include and which should I exclude from the backup? I use docker a lot, is there any docker-specific directory that I should back up?

I have used a combination of rsync and borg to backup to an external drive. Then I was feeling adventurous and tried borgbackup2. It was a mistake. Then I learned of rdiff-backup. Easy to setup, but even incremental backups of my home dir took many hours to complete. This is no solution to have regular backups for me.

I decided to go with btrfs snapshots instead. I recently reinstalled everything and I have finally btrfs. I bought a new external NVME drive for my backups where all the snapshots will go. Btrfs has even a parent-option to copy incremental snapshots to another filesystem (the parent snapshots being on both filesystems).

I did not finish my setup, so I cannot share any scripts yet.
