Literally any tech company paying US engineering salaries? Try to calculate what a bay area engineer makes hourly sometimes, then go ahead and flip that AWS cross-region data replication checkbox (and maybe make your S3 bucket immutable too, storage is cheap), then tell your boss that you just saved the company a whole bunch of money compared to your team cobbling together some janky bespoke backup solution that nobody will remember how or if it works 12 months from now.
