Calsoft was engaged by the client to change Block Tracking (CBT) for Hyper-V.
The engagement primarily involved:
Tracking change VHD/VHDX blocks and map them to VM disk changed blocks
The mapping algorithm to be VM OS agnostic that would assure accuracy
Tracking to be minimally intrusive on I/O performance and optimal memory utilization
Zero VM/Hyper-V host downtime during deployment and tracking
