Why did you stop quoting after "immediately overwritten" ?
> ie that the backup is simply held on your systems until it is replaced in line with an established schedule
Again, you can't keep backups forever, you are _required_ to delete them.
Also, not sure why you keep you backups in the bank (do you, really?) but even banks can suffer from fire/arson, explosion (accidental or not), or a number of other natural disasters (earthquake, flooding, etc).
[later edit] Also, sort of by definition, in all businesses customers trust you to do your job. Can you give an example of a business where customers don't typically trust you to do your job?
Really depens on the industry and the country (Finance is 30years, Health-Insurance until the death of the person (in switzerland)) You cannot go to you finance institute and ask them to delete all you records...that will never happen.
>Also, not sure why you keep you backups in the bank
Business backup's, secure, really good fireprotection, flood protection and in case of a Bus-hit-scenario someone else has access to it.

Politic and Canon filehosting from now on, Airbus Max and Foxnews ;)
Right to be forgotten does not apply in cases where you're legally required to keep the data, or have other legitimate reasons to require said data, or there's significant public interest. But for _my_ photos, on a hosting service, it most definitely applies - if I request erasure, you can't keep them 30years in backup without breaching the law, that much I guarantee.
> Politic and Canon filehosting from now on, Airbus Max and Foxnews ;)
I know it's tongue-in-cheek, but Foxnews viewers typically trust them, that's one of the problems, right? And customers (advertisers) obviously trust them to deliver message to audience.
Airbus is better trusted than ever, especially now after the 737 Max fiasco :P - but even Boeing was obviously trusted by their customers (whether that trust was misplaced is a different issue; my point was "customers must trust me" is in no way unique or particularly important for file hosting).
>>The key issue is to put the backup data ‘beyond use’, even if it cannot be immediately overwritten.
It's clear that you cannot delete WORM-tapen with many other data on it.
>This is just opinion.
Not for a file hosting service, the customer trusts you to do your job.
>If it gets destroyed, is it a backup?
Destroyed means physikal interaction, since it is not possible to make a reallife backup this is you last line of defence.
>Can your backups be accidentally destroyed?
Well if someone "accidentally" breaks into my bank opens the right tresor and "accidentally" uses a flametrower..the you are right.
