Reading Time: 3 minutes As you probably know VMware vSphere 6.0 had a critical issue con its Change Block Tracking (CBT) implementation that can impact all incremental backup with “VMware native” backup program (all agent-less implementation using the VMware VDAP API). This issue occurs due to an issue with CBT in the disklib area, this causes the change tracking information of I/Os that occur during snapshot consolidation to be lost. The main backup payload data is never lost and it is always written to the backend device. However, the corresponding change tracking information entries which occur during the consolidation task are missed. […]

Windows 10 support has been introduced in version 1.1 and it works well, but after the Threshold 2 (or Fall Upgrade) some Veeam Endpoint Backup database files could be moved during the OS upgrade procedure. It’s not sure yet if all version are impacted or only Windows 10 coming from a previous major upgrade (Windows.old is normally used to keep a rollback for an in-place upgrade).

Reading Time: 3 minutes Changed Block Tracking (CBT) is a VMware feature introduced in vSphere 4.0 in order to implement native incremental backup at source level. VMware VDAP uses this technology and so all backup and recovery software designed for VMware use it for speed the backup. But last week a critical issue has been discovered on all vSphere 6  version (included the lates Update 1a) where Changed Block Tracking (CBT) data on ESXi 6 cannot be trusted.

Reading Time: 2 minutes As promised Microsoft does not release anymore “Service Pack” collections (the idea is move to a “Windows as a Service” upgrade model), but this does not mean that does not release cumulative upgrade.

Of course the Windows Insider will continue (and there is also a similar program in the new […]

Reading Time: 4 minutes As written in a previous post, the nested virtualization will be one of the future features of Microsoft Hyper-V. Actually Microsoft simple does not support nested virtualization in its Hyper-V product. Nothing wrong with it, but it’s a case where not supported means also that it simple does not work at all. And usually for production user cases it’s not necessary. But for testing and labs this features could be really useful, expecially in the client side of the hypervisor. In fact this feature has already been added to Windows 10 (starting with  the build 10565 of Windows Insider version).
