>Nah, you can snapshot every 15 minutes.

obviously you can. but, what is the actual snapshot frequency? like, what is the timestamp of the last known good snapshot? that is what matters.

in any case, the comment you are replying to is a hypothetical, which correctly points out that even a day or two of lost edits is fine (not ideal, but fine). your reply doesnt engage with their comment at all.

I did engage, by pointing out that it wasn't relevant nor a realistic scenario for a competent sysadmin. (Did you read the OP?) That's a /you/ problem if you rely on infrequent backups, especially for a service with so much flux.

? Why would I know what their internal operations are?

i mean... you must, right? you know that once-a-day snapshots is not relevant to this specific incident. you know that their sysadmins are apparently competent. i just assumed you must have some sort of insider information to be so confident.

I think you are misreading my comments and made a bad assumption. The reason I'm confident is because this has been my bread and butter for a decade.

my decade of dealing with incompetent sysadmins and broken backups (if they even exist) has given me the opposite of confidence.

but im glad you have had a different experience

Oh, I agree that the average bar is low. That's part of the reason I do it all myself.

The heuristic with wikimedia is that they've been running a PHP service that accepts and stores (anonymous) input for 25 years. The longetivity with the risk exposure that they have are indicators that they know what they are doing, and I'm sure they've learned from recovering all sorts of failures over the years.

Look at how quickly it was brought back up in this instance!

So, yeah. I don't think initial hypothetical counterpoint holds water, and that's what I have been pointing out.

Kudos for very polite responses to trolling.

I have good faith, though I should get off hn now... :P

I still don't need to assume what the intent is. Troll or no troll, it works. My comments might inspire someone else to try a CoW fs. I'm also really impressed with wikimedia's technical team.

no one is trolling in this comment chain.

i found kibone's reply to a hypothetical musing as if it was some counterpoint in a debate instead of a simple expansion on their comment to be off putting. we had some comments back and forth and we both came out of it just fine. weird of you to add on this little insult to an otherwise pretty normal exchange.

		FWIW I did not assume that you were trolling, and yes we did come out fine.
