Like does this give you a sense of superiority?
I could have said: Been there bought the T-shirt and I feel your pain. Which would be true. The person would have not felt better in any way because the data is gone, and would not have learned something either.
Does the person feel worse because of my comment? Don't think so. Either he already new and agrees with 'Yes, d* it should have done that, you're right' - what I felt someone said this to me - or he learned something. Perhaps if getting kicked hard enough he will not skip backups next time.
Does he feel bad? Sure.
Does anyone think about the people who he dragged down with him because he didn't have backups which would have been something he is paid for but didn't - do risking the jobs of everyone around him.
When consulting the FIRST thing I ask:
DO YOU HAVE BACKUPS FOR YOUR AWS/GOOGLE/... DATA?
And if not do it now - although the usually answer is: This is the cloud I don't need backups because they backup the data/redundancy/S3/... What about someone deleting it? By accident or itention? What about you getting sued by A/G/MS/...? What if they kick you of like XXX (Parler, ...)?
Most do backups to a another provider the same day.
Not having backups if you're the one responsible is not the same as getting cancer or being hit by a car. It's you've screwed up very badly endangering many other people.
For the rest, you're completely right. Everything possible should've been backed up. It just has nagged me that a real backup isn't possible, and it has bitten me in the past (corrupted drawing, which corrupted related documents as well). Since then, I have only used the Google sheets/documents/etc. for throwaways and drafts.
If you have critical data that can cost your company that you can't backup, your're living a risky life. Hopefully they've checked with their colleagues that those agree with living that risky life.
