Most of my work is with Macs, and even one server is running macOS, so for those who don’t know how it works ‘over there’, one runs Time Machine which is a versioning system keeping hourlies for a day, dailies for a week, then just weeklies after that. It accommodates using multiple disks, so I have a networked drive that services all the mac computers, and each computer also has a USB drive it connects to. Each drive usually services a couple of computers.

Backups happen automatically without interruption or drama.

I just rotate the USB drives out of the building into a storage unit once a month or so and bring the offsite drives back in to circulation. The timemachine system nags you for missing backup drives if it’s been too long, which is great.

It’s not perfect but very reliable and I wish everyone had access to a similar system, it’s very easy, apple got this one thing right.
