Thanks, that's how we enable and disable! <br />

We've also got tools that track the data changes! But we've not documented them for general release. Some day, when we get time. So you can check how much the VM is changing on a daily basis in MBs and GBs.

I have backup software that uses CBT but I have recently clear all the backups and started with a new target. What happens is the software does not realize it should backup the whole machine the first time because it is still reading the CBT and only backing up the blocks that have changed. <br />
<br />
Is there a way to reset the CBT on a VM back to 0 or whatever?

Clear Change Block Tracking Index of VM

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
