Does IBackup support incremental backups for VMware virtual machines?

Yes, IBackup supports incremental backup for VMware virtual machines. To do so, you need to first enable Change Block Tracking (CBT).

To enable CBT,

  1. Power off the virtual machine.
  2. Right-click the virtual machine and click 'Edit Settings'.
  3. Click the 'Options' tab.
  4. Click 'General' under the 'Advanced section', and then click 'Configuration Parameters'. The Configuration Parameters dialog box appears.
  5. Click 'Add Row'.
  6. Add the ctkEnabled parameter, and then set its value to true.
  7. Click 'Add Row', add scsi0:0.ctkEnabled, and set its value to true.

Note: scsi0:0 in scsi0:0.ctkEnabled indicates the SCSI device assigned to the hard disk, which is added to the virtual machine. Every hard disk added to the virtual machine is given a SCSI device similar to scsi0:0, scsi0:1, or scsi 1:1. The CBT option is either enabled or disabled on each disk.

How do I disable Change Block Tracking (CBT) for VMware backup?

To disable CBT for VMware backup,

  1. Power off the virtual machine.
