syncthing falls down when you hit millions of files.

Platform agnostic? Rsync from the perspective of duplicating the client-presented data.

Or rclone, another great tool. I tend to use this for storage providers instead of between self hosted systems (or data center fully self-managed systems.)

If the NAS uses zfs then zfs send/recv is the best, because you can send only the changed blocks. Want to redo the names on every single movie? No problem! I do recommend sanoid or syncoid, I don’t remember which. ZFS snapshots are not intuitive, make sure to do LOTS of testing with data you don’t care about, and which is small.

In terms of truly duplicating the entire NAS, we can’t help without knowing which NAS you’re using. Or since this is selfhosted, which software you used to build a NAS.

But then again they have no health care costs whatsoever.

I’m on mobile but didn’t see anything having to do with gender differences in training, only country based, which was not my point at all.

Right in the first part, but for the second: police come in more than one gender and the training is the same.

(Afaik on the training part - I welcome being proven wrong!)

Google won’t sell YouTube.

Backblaze b2 and rsync.net (which shouldn’t be a problem for rclone)

Neither is sketchy in the slightest and run solid services with many options.

Have you isolated source formats? Does it do this with h264 and hevc?

Tried stopping other containers and/or all other services? Could have less to do with pure power and more with sheer volume (scheduling.)

Any issues if you use the current server as a file server and play the video on another machine? Any modifications to playback speed?

If none of that works you might try iperf3 to check network speeds. Or fio for disk speeds. Run tests covering all kinds of situations, you’re not so much looking for max speeds but instead for inconsistencies.

Don’t get too lost in the small stuff. Isolate systems. Might even move or clone the boot drive to another machine as a test. Try a different switch. That kind of thing.

Good luck!

Could be cheaper than getting sued for one or more people’s deaths.

As stated too: only post a certain temp, otherwise I know there is zero chance of it.

Banning people from bringing in their own drinks is incredibly normal afaik. What no one has mentioned that I’ve seen is: What was the hydration plan of the concert organizers?

Was bringing in empty bottles and filling them inside ok?

How about providing free or inexpensive water once it got past a certain temp?

Misters? Heat relief booths? Onsite medics?

How can we have any clue whether the organizer has any blame if we know nothing about the situation, other than the fact that someone later died?!

Without this info the story is basically pointless - maybe the organizers took heroic steps and a young person got caught up in the excitement with tragic consequences. And maybe the concert provider is a borderline criminal organization who needs to be fined, or shut down, or both. Plus stricter government regulations. But no, we know nothing - thanks Reuters!
