Upon backup, replication or recovery job, one of the following messages is displayed.
VMware CBT (Changed Block Tracking) , Hyper-V RCT (Resilient Change Tracking) and Nutanix CRT (Changed Region Tracking) are the technologies to track changes on the virtual machines. NAKIVO Backup & Replication uses these technologies to create incremental backups faster. If the usage is not possible, NAKIVO Backup & Replication uses proprietary change tracking method which works slower.
