1. Follow the site-wide rules
- Instance-wide TOS: https://legal.lemmy.world/tos/
- Lemmy code of conduct: https://join-lemmy.org/docs/code_of_conduct.html
2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack members of the community for any reason.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
- These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudo
in Windows.
- No porn. Even if you watch it on a Linux machine.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
Please report posts and comments that break these rules!
Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

That's committing the cardinal sin of cherrypicking your backup contents. You may end up forgetting to include things that you didn't know you needed until restore time and you're creating a backup that is cumbersome to restore. Always remember: you should really be creating a restore strategy rather than a backup strategy.
As a general rule I always backup the filesystem wholesale, optionally exclude things of which I'm 100% sure that I don't need it, and keep multiple copies (daylies and monthlies going some time back) so I always have a complete reference of what my system looked like at a particular point in time, and if push comes to shove I can always revert to a previous state by wiping the filesystem and copying one of the backups to it.
