I like to point out that delete all files might be impossible anyway, especially in Banks that record 24/7 a day. They do backups, if a bank claims - we delete all footage after X days, then they also need to delete all backup material, which I doubt they will do. The effort is very high.

I claim they delete or hide stuff from the normal storage servers, but they do not delete the backups and also I doubt that partner servers or other backup servers will do that. The effort to delete everything and hide specific things from backups would be huge and in not practicable. GDPR or DSGV also is not specific what delete means, physical delete files, or does it include backups too etc.

If I were a bank I would only delete stuff if,… if I ever run out of storage. Keeping such material is to value overall in case you need to go back 1 month or more to investigate a gang. Check how thieves checked out my bank and build strategies, some gangs work over MONTHS to exploit a bank’s weakness.

As said, you e.g. pay Amazon, Google these days for CPU time, the storage has no limit, Google even mention that directly that there is no limit, I mean there is but I saw piracy groups hosting PETABYTES of movies on Google Drive.

Yeah, no one said anything for free, in that I agree with you, but is cheaper than self-hosting, which was my overall point here. Which is why I mentioned some examples.

Maybe my definition forever is up for debate, but certainly more than they admit they do… Maybe only 7-10 years. No one knows. I know in Germany the fed keep documents 7-10 years, must do by law.
