Traditional backup solutions are able to back up virtual guests on a VMware ESX host; however, the resource utilization on the host and the backup time required quickly become areas of concern. The NetBackup PureDisk client running in a virtual guest provides excellent deduplication at the source and can back up with less continuous load and much shorter backup durations. All clients that back up to the NetBackup PureDisk storage pool will realize the benefits of global deduplication. If a lesser load is desired on the VMware infrastructure, the NetBackup PureDisk client deployed on the proxy provides the same excellent deduplication, but the trade-off is the minor scripting that is required to produce a snapshot of each virtual guest.
