  • Live Mount VMDK to VM?
    Posted: 03-02-2019, 7:31 AM

    Hi there,


    I can see that it is possible to do Live Recovery of VM, where they run from the backup storage without being restored.

    Also, I can see the option to mount vmdk to another VM.

    But what I can't do is to live mount the vmdk, without restoring it first. Basically, I would like to attach a vmdk to a running machine from the backup storage, without having to restore it.

    Is this possible?

    I'd like to know this answer as well. Anyone? McFLy?

    We don't have that capability exposed out.  Live mounts are built into a VM lifecycle policy so we are able to clearly state that this entire VM is backed by secondary storage and will eventually expire.  So we can make it clear that the VM is temporary and data will be discarded.  It becomes a lot harder to make that clear when one disk pops up on a VM that is being used for other purposes; but anything modified on that disk will be thrown away at some point.  Especially if the VM is owned by someone other than the person doing the restore.

    As long as you are aware of the temporary nature of the disk you could simulate this by performing a live mount; powering off the VM and then attaching the disk to the existing VM.  Admittedly that is a bit more work, and something nicely integrated would be better.

    Can you tell me a bit about what your use case for this is?  Most of the time when I hear about this it usually to perform file level restores; and that should be handled by the guest files restore; but I’d love to hear more about your case and perhaps we can build something that suites your need.

    Hi Henry,


    My use cases are:

    - Use "offline miners" for unsupported applications.

    - Use better third-party "offline miners" for some supported applications

    - Use specialized applications to browse data from a VM (ex.: say a DWG viewer, to find a certain project file), without having to restore all the files

    - Restore data that is stored inside bigger files, inside a VM (say, something inside a ZIP) without having to restore the full file
