Improved VMware Backups in release 10.8.2 and later

We've improved our VMware backup offering by implementing a more efficient VMware API that optimizes both full and incremental/differential backups.

While creating new full backups is optional, it's recommended to take full advantage of the reduced backup sizes for your VMware VMs.
