If you use the same repo for all servers, note that all servers will see each others backups as imported/foreign objects (or encrypted objects if your backups are encrypted) because it has no information about those restore points in it’s own database but it will see those restore points in the repo. My recommendation would be that you create 3 separate folders on your backing storage, one for each repo, one repo for each server. But a very slight change might work for you.
