Heads up with backing up > 2TB VMDK disks using HotAdd

If you are using HotAdd to backup VMDK disks which are larger then 2TB while running vSphere 5.5 be warned that this will fail silently as described in KB2068424.

  • When using the HotAdd transport mode, you are unable to back up disks that are 2 TB or larger in size.
  • Backing up disks larger than 2TB in HotAdd transport mode fail silently, but report a successful back up on Windows virtual machines.

VMware currently has no workaround for this! If you are using Veeam make sure you check out the solution provided by Luca.
