You can't copy the Virtual Disk file while it is mapped to the Virtual Machine mode: This method works not only with the ESXi Hypervisor, but also with VMware Workstation or older products like GSX or VMware Server. Many years ago, this was my first method of creating backups of running Virtual Machines. The most unsophisticated backup method would be to simply make a copy of all files. The post explains the technique to create backups and takes a look at solution that use these techniques.Īll Virtual Machines are just files on datastores. The API limitation makes it impossible to create incremental CBT aided backups, but it's not impossible to create full copies of virtual machines.
