The idea of the github fonts is interesting, but I find it strange that the same letters next to each other can have different widths. I currently prefer the CommitMono approach.
My server uses zfs, which allows me to create regular snapshots with sanoid. This makes it extremly easy to quickly recover individual services or vms without consuming a lot of disk space. In case the server is not recoverable, I still send the incremental snapshots to a pi clone with a large hard drive. If you use the native disk encryption, the snapshot can be sent encrypted without the second server having access to the data.This solution with zfs and sanoid/syncoid has often made my life easier and, in my experience, uses less bandwidth and cpu load.
The files are stored in a directory and you can define the default path with an environment variable ( file-name-handling ). If you need a more fine graint solution you can also use storage paths and select it on file level ( storage-paths ). I'm using syncthing to sync the folder structure to my other devices.
