Windows Server 2016 Datacenter Backup and Restore Issues with Cluster Shared Volume

Good day,

I am running a Windows Server 2016 Datacenter 2 nodes hyper-converged cluster. I am using Storage Spaces Direct to create a Cluster Shared Volume (1 TB virtual hard drive). In order to be accessible on both nodes, it creates a volume path on the C: Drive where my OS is installed.

OS: 120 GB SSD

CSV: 1 TB

The issue: When I backup my C: Drive (by using Windows Backup or any other backup solution), it runs fine. However, when I am trying to restore C: Drive, it says I don't have sufficient space to restore the image and I need at least 1 TB drive (the 1 TB CSV is seen as "part" of C: Drive).

The question: I know my setup can't use a drive letter, but is there a way to "hide" the CSV when performing OS backups?

Thank you!

    Hi,

    Thanks for your question！

    If you want to backup your OS, we can ues system state backup or Bare metal backup instead of backup C drive.

    System state backup: Backs up operating system files, enabling you to recover when a machine starts but you've lost system files and registry. A system state backup includes:

    Domain member: Boot files, COM+ class registration database, registry

    Domain controller: Active Directory (NTDS), boot files, COM+ class registration database, registry, system volume (SYSVOL)

    Machine running cluster services: Additionally backs up cluster server metadata

    Machine running certificate services: Additionally backs up certificate data

    Bare metal backup: Backs up operating system files and all data except user data on critical volumes. By definition a BMR backup includes a system state backup. Provides protection when a machine won't start and you have to recover everything.
