Let’s say you’ve grown attached to some of the workloads you’re running on one of your clusters, naturally. It would be nice to backup and restore those should something go wrong - or even, as was my case, I deployed a distro of K8s on my Raspberry Pi cluster that I wasn’t wild about and wanted to move to another - how do you migrate those workloads?...

Veeam Hot-Add Mode Fails – Mismatching VMFS block size

Recently had a problem were Veeam was giving bother on one VM that had a dedicated datastore, not allowing hot-add virtual appliance mode to work.
