My nephew set this up for me back in 2022. We have the internet box at the office, it's one of those DELL POWEREDGE units with 64 RAM (I think that's the memory? Or is that the hard drive?). I told him we need backups and he said the host does snapshots. I pay OVHcloud monthly for this -- https://www.ovhcloud.com/en/vps/. Is that enough??
I also have a USB stick I copy files to sometimes. My nephew says that's "old school."
Curious what everyone else actually does. Not what you tell clients you do. The real thing.
