Various methods and techniques are disclosed to manage resources of virtual backup appliances in a backup and recovery network. In one embodiment, a backup server receives a request to decommission a virtual backup appliance (VBA) of a first primary storage system. The backup server is configured to manage backup operations to back up data from a plurality of primary storage systems to a backup storage system over a network, where each primary storage system has one or more VBA that carry out backup operations. In response to the request, the backup server transmits a first request to the first primary storage system over the network to delete data and metadata related to the data associated with the VBA. The back up server then determines whether the backup storage system contains data associated with the requested VBA. Upon the determination, the backup server transmits a second request to the backup storage system to delete the data associated with the requested VBA from the backup storage system. The backup server then deletes a second metadata associated with the VBA, and then unregisters the VBA from the backup and recovery network.
