    I have a small cluster running using Starwind for my vSAN. For me it’s much cheaper than a hardware equivalent and is performant enough.

    Oh and I haven’t had a “stop work” issue with it in 8 years.

    Somewhat remarkably it was OK performance-wise when sync/iSCSI traffic were running on 1Gb copper connections to spinning rust storage… Now I have 10Gb fibre between the hosts, coupled with nvme drives, and it’s quite (comparatively) quick.

    As with all things YMMV… But vSAN is the way for my use case.

    We used to use virtual box on windows with an immutable hard disk to boot the environment with storage, for persistence, elsewhere (usb for example) if required. Just used standard ubuntu for the guest distro.

    Once you shut down the VM the vhd reverts to as installed. It’s a bit painful distributing the system but can be done.

    You can prevent ordinary users messing with the immutable setting as well if that is a concern.




  • Is VSS even a backup?

    Nope, not even close.

    I thought it just copies old revisions of files into that shadow area

    It just copies the deltas…

    Backups can use vss to get a static image of the volume (deltas are written to the shadow area, which isn’t backed up, whilst the backup is running) it’s a little different for vhdx files on VMs but basically the same.

    It’s magic… And often means that I don’t have to restore lost files from backup, just view the old versions and grab a copy from there.
