Is he under an obligation? No. Is he, and any other professional who doesn't, an idiot for not backing up his data? Yes.
He is dead. Any backups he might have made might be long gone, or otherwise, unknown. What we do know is that the IG posts AND the backups done via the Internet Archive are gone.
So, my question to you is: where can you set a backup for no cost, available from Gaza, and that won't be taken down 3rd parties. Note, anything online has the potential to have data removed, and even then, we don't know what other backup locations he might have been using. We just know what was available now to the public.
In addition, let's say he had hardware backups (which are now gone after he was killed), or let's say just a random S3 bucket. We have to know about it. Know how to get access to it. And hope that AWS doesn't nuke it because someone asks them to do it.
It's a big mess, and blaming him for not having more backups than an entire country is incredible.
It gets deleted. TOS violation.

Not necessarily. No capable person that understands tech at all would think this.
> or any other cloud storage where you maintain ownership of your data.
If you don't own the infrastructure, do you really own it? And none of these are resilient to takedown requests, or other means of removal.
> Internet Archive allows takedown requests from content owners,
That's not what happened here. He was the content owner. Also, you pretend like other groups don't also do that.
> You can give people anywhere in the world the credentials to access it:
Like IG did?
None of your solutions meet my criteria in the slightest.
We do know that he is dead, though.
