We have just added a WinSrv2019 Hyper-V host running two virtual machines (one Domain Controller 2019 and one MS Exchange 2016) without joining the host to the company domain.
We need to back up this host but all the network shares are not accessible despite this trick.
The questions are:
- Should we purchase an external NAS for this purpose?
- Does another safe way to backup to a network share exist?
- Are there other options we are not considering?
