Examples described herein include systems and methods for backing up and recovering a software-defined data center ('SDDC'). In one example, entities of the SDDC, such as virtual machines, hosts, and clusters, can coexist with corresponding entity stores. The entity stores can store current state information for each SDDC entity. For example, an identifier or name of a virtual machine can be stored in that virtual machine's corresponding entity store. When recovery of a controller is needed, the controller can rebuild state information that has changed after the controller was backed up, by retrieving state information from entity stores of the various SDDC entities.

Recovery of a software-defined data center from persistent entity stores for virtual machines

Recovery of a software-defined data center

Exemplary methods, apparatuses, and systems include a first virtual infrastructure manager (VIM) determining that the first VIM is to be an active manager of a plurality of virtual machines running on a plurality of host devices and that a second VIM is to be a standby manager of the plurality of virtual machines. The first VIM selects a first host device from the plurality of host devices to serve as a passive witness node in arbitrating active and standby roles between the first VIM and second VIM. The first host device runs one or more virtual machines and is managed by the active manager. The first VIM selects a first host device by confirming that the first host device is available to each of the first VIM and the second VIM. The first VIM writes a file on the first host device indicating that the first VIM is the active manager.
