Going forward though, Vimeo feels like a better fit for you guys. Caveat emptor, never rely on free services for critical parts of your operation.
Don't rely on a single service. Having the same data at two free services is probably more safe than relying on a single paid service. At least for data loss.
If data is sensitive don't rely on any service, just encrypt it with your own key.
Given how giant companies (especially Google) behave, I do not feel it is an esoteric thing to do. Anyone with even a modicum of technical skill can roll their DIY NAS. For the non-tech savvy, buying off the shelf is fine.
Should not be needed in real life but this is the world we live in where robots have way too powerful ban hammers and the only way to get any support is to make sound in public forums or have a large social following.
Then depending on what you want out of the device, do one of the following -
1. If it's strictly storage and you want the niceties of ZFS, install TrueNAS 2. If you want expandable storage without ZFS + VMs + Docker with a nice GUI and are willing to pay for a license, install Unraid. 3. If you want ZFS-backed storage + VMs and no docker, and maybe some datacenter-style capabilities, install Proxmox 4. If you want all of the above and are willing to manually configure everything, then install Ubuntu Server + Cockpit for managing the machine headless + Portainer for managing a large number of docker containers.
