Number of servers is orthogonal to the goal in this scenario. You need
to backup one or couple IPA replicas. You do not need to back up all IPA
replicas and clients. This should not be a big impact on your storage
You are welcome to try to create a backup script for IPA but we decided
to back away from this effort as it is a much bigger effort that might
seem on the surface.
