I was facing this problem when selecting a backup strategy for client machines. Servers are one thing where i can rely on them to be always running, but clients go off grid occasionally. As for restic, yes it's available on Windows, but has a serious speed degradation when datasets increase above 2TB, mainly due to chunks being 2-5MB, where Borg uses 400MB chunks. And we're not talking a 10% slowdown. It's to the point where prune operations on repositories >2TB can/will take multiple days to complete. For clients, I evaluated multiple solutions, one was Duplicati (https://www.duplicati.com/ https://www.duplicati.com/), and while it appears to work well most of the time, it sometimes stops backing up for no apparent reason. Backuppc also looked promising, but doesn't (didn't ?) support source encrypted backups. In the end i ended up with Arq (https://www.arqbackup.com/ https://www.arqbackup.com/) for Windows and Mac clients. It works reliably, and checks all the right boxes. For servers i was initially really hooked on restic as it allows backups over HTTPS instead of SSH, but the performance issues were a showstopper.
