Practically speaking, I think a lot of what is offered by Microsoft, Google, and the other big companies that are selling into this space is vastly overpriced and way too full of lock-in, taking this stuff in-house without sufficient knowhow and maturity is even more foolish.

It's like not hiring professional truck drivers, but instead of at least people who can basically drive a truck, hiring someone who doesn't even know how to drive a car.

Now, sure, there is AWS Backup and Microsoft 365 Backup. Nevertheless, those are backups in the same logical environment.

If you’re a central government, you still need to be maintaining an independent and basically functional backup that you control.

I own a small business of three people and we still run Veeam for 365 and keep backups in multiple clouds, multiple regions, and on disparate hardware.
