Use Changed Block Tracking (CBT) to perform incremental backups on virtual machines running on VMware ESX/ESXi. CBT identifies and tracks
block changes since the last backup, and stores these changes in log form, greatly reducing the number of backup windows and improving
backup window times. Additionally, subsequent replication efficiency and speed are improved.
