If I budget enough to store 1TB of data for 1 month, then on the first day of the month I store 2TB of data - what should the behaviour be after 15 days?
Read/write access should be frozen, data should be saved for 1 month so you have time to react to warning emails. If you didn't upgrade in that time, it should be deleted.
Nuke the data. It’s gone forever if you didn’t back it up elsewhere. This should be a meaningful risk mitigation that I can employ to avoid having a catastrophic financial disaster.
This isn’t a limit I’m setting at some percentage above expected costs, it’s: “I don’t want to take out a HELOC if something goes wrong”
Unfortunately, a lot of people keep their backups in the same cloud account as their primary data. Thinking that multiple copies and multiple availability zones are sufficient.
For these users, the article’s €54k bill would be replaced with their business data getting wiped out.
