  • VSA restores VMDKs as thick?
    Posted: 03-13-2011, 1:23 PM

    I just had cause to do a restore of a VMDK.  I noticed that the restored VMDK is thick provisioned whilst the VMDK that I backed up is thin provisioned.

    How can I make Commvault restore a VMDK in the same format that it was backed up please?

    We're using 8.0 SP5 and the backups are VADP.

    Thanks,

    Paul

    Hello Paul,

    I believe the workaround is to restore then do Storage vMotion to Thin Provisioned.

    Thanks JW, after I did the restore I did a migrate to/from another volume to convert to thin.

    Do you happen to know if this is a Commvault limitation or a vmware one?

    If it's the former are there any plans to change it please as whilst in a DR scenario you have bigger things to worry about than disk space, it's not nice having to allocate 40gb for every single VM even if the actual data is only 7-8gb - it defeats the point of thin provisioning.

    (storage vMotion is only in => vmware Enterprise so we don't have that)

    Thanks,

    Paul

    Paul,

    I did come across some VMWare links that discuss similar issues to what you are experiencing:
