System Administration: Week 10: Backups, Part I

In this video, we begin our discussion of backups by covering some core concepts and terminology, looking at full vs. incremental vs. differential backups and the difference between long-term storage and disaster recovery to recovery of files due to more localized data loss.

@Ashedryden I mean, given I keep some of those sites online professionally, yes. Every day.
Do you ever end up on a website that hasn't been updated in years and its design aesthetic takes you back to a time and place on the internet?
Quick reminder, especially if you’re a freelancer or developer using Free/Pro/Pro+ plans for client work: Opt out of GitHub using your data for AI model training before April 24 (seriously, wtf that this isn’t opt-in!).

New article out! Super in-depth, very furious manifesto. I get batted around. Join in the fun! Looks like it was a lot of work.

It is amazing that computers work at all.

One of my favorite research papers along these lines is "When the CRC and TCP checksum disagree": https://dl.acm.org/doi/10.1145/347059.347561

By looking at cases where the Ethernet CRC indicated no error, but the TCP checksum was invalid, the authors found a whole host of bugs in networking hardware, such as faulty DMA engines and buggy router memory.

Hardware data corruption is everywhere!

(There are no doubt newer studies, I'm just personally acquainted with one of the authors.)

When I see people going "the archive is slow, wah" they just don't realize there's this tsunami of bad actors, either spammers, DDOSers testing their equipment, and fraudsters that want to just grind the whole thing into the ground to make a potential quick buck. I'm flghting them and others are too. But the result is I'll spend a full day and have little to show for it.
if anything, i've found that the quality of his posts have gone down over time, i call this "doctorowification"
