Recover server backupfrom external drive

MB 20 Reputation points

Backing up Win 2016 server VMs on a host running Win 2019. The hyper-v files for one of the 2016 server VMs was corrupt. We were backing up that 2016 server with Windows Server Backup to an external drive, which according to the articles I read at the time, needed to be set to offline of the 2019 host, then attached in the 2016 backup server.

When it became clear that the hyper-v files were not salvageable, I tried to see the files on the external, but it appears offline though it appears in the disk manager in the host.

  1. If I flip the external to online, will this damage the data?
  2. Is there a recommended way to recover the server image so that we can build or recover to a new VM?

    Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query.

    I have linked an article below that may help solve your issue. Here is what the article has to say:

    Connect the external storage device that contains your backup files.

    In the search box on the taskbar, type Control Panel, then select it from the list of results.

    In the search box in Control Panel, type File History. ...

    Follow the instructions to restore your files.
