It seems like a solid plan but what's missing is no matter if you're doing 3-2-1 or using simpler solutions, you should test if the backup works periodically. Or else over the years, the backups would die one by one and nobody noticed, it defeats the point of so many redundancies. Also there's a chance the backup data is corrupted or incomplete (especially due to the design) so it's not possible to restore the system. Just test it periodically. If there's a backup process you should also test it too. Scenarios like backup job workers are stuck and the system is not actually backing up is not uncommon.
