Backup Agent Considerations

Using the Virtual Server Agent in HotAdd Mode Configurations

  • When deploying the Virtual Server Agent, install the software on a datastore with the largest VMFS block size. This is necessary to ensure that the Virtual Server Agent can mount and back up virtual machines residing on all datastores.
  • Helper virtual machines are not required for HotAdd Virtual Server Agent servers using VADP.

Changed Block Tracking

Changed Block Tracking (CBT) is a VMware feature that can be used to optimize backups of virtual machines by reading only the allocated and modified portions of a virtual disk. CBT is automatically enabled for virtual machines running on hardware version 7 or higher.

For more information on Changed Block Tracking, see Changed Block Tracking (CBT) on virtual machines (1020128).
