Incremental backups can be modified with the following operations:
| 
 •  | 
 Active Block Mapping (ABM): ABM scans the disks on a VM and detects the blocks actively used by the disk, as opposed to blocks that were deleted by the Windows® operating system. With ABM enabled, vRanger only backs up the part of a virtual disk that has active data on it. ABM also provides the following settings options:  | 
| 
 •  | 
 Changed Block Tracking (CBT): CBT reduces the time needed for incremental and differential backups by only backing up the portions of a disk that have changed since the last backup. By determining which blocks changed within the VMDK file, vRanger only backs up the portions of a disk that have changed since the last backup. This often results in shorter durations for backup operations, and reduced resource consumption on network and storage elements.  | 
| 
 NOTE: CBT does copy deleted blocks if ABM is not also enabled. CBT is a VMware® feature, and does not apply to physical machine or Hyper-V® VM backup.  | 
For more information about selecting the ABM and CBT operations, see Configuring backup options.

 The Threshold Size refers to the percentage of the hard disk of a VM that must be captured in differential backups before performing a full backup. Using the Threshold Size value might cause your full backups to be taken on unexpected days.  |
