Since vSphere 6.5 the HTML5 client (vSphere-Client) is an integral part of the environment and is geting updated with more and more features with every release of vCenter. It is to get rid of the infamous flash client (web-client) sooner or later.
In distributions below 6.5 there’s no HTML5 client included. But it is possible to get the functionality with a fling.
A typical Veeam Backup & Replication installation consists of several sub-components. There is the Backupserver with the database, there are backup proxies, Mount Server, Gateway server and Backup-repositories. Repositories are datastores which hold your backup data. Right after initial setup the installer will create a repositoty on your system partition which is the default repository. Normally your system partition isn’t very big. Maybe 100 GB or less. One of the first tasks after installation is to define a new backup repository with Terabytes of free space. Sometimes you might forget about the default repository, which is pointing at your system partition. Under certain conditions this can turn into a timebomb which I witnessed in the wild recently.

Microsoft’s monthly March 2018 rollup KB4088875 contains a patch KB4088878 which seems to have issues with Windows Server 2008 R2 VMs and VMXNET3 adapter. Applying the patch disconnects Windows Server 2008R2 VMs.
Yes, indeed! There used to be an old problem with Server 2008R2 VMs which had a VMXNET3 NIC. After restoring these VMs from backup, they’ve lost their static IP and instead switched to DHCP. The problem is known by VMware and there’s a corresponding KB1020078.
Microsoft released in a hotfix 433809 (KB2550978) to prevent the issue. But you had to switch to DHCP first before installing the hotfix and then revert to your static IP. I’ve published the procedure in 2013. This blogpost is in German but the procedure is simple:
It seems that Microsoft now has included that old hotfix into a montly rollup. At least the similarity is striking.
Those who had already applied the Hotfix in the past to their 2008R2 VMs, seem to be immune to the problem.
Microsoft’s file system ReFS is around for some time now. Windows 2012 already brought us the initial version almost six years ago. Still we had to wait till Windows Server 2016 appeared to get the real killer feature – at least as far as its usage for Veeam backups is concerned.
