    摘要： In one embodiment, a virtual machine replication system may test a replica data set while continuing to replicate a primary data set. A data storage 250 may store a replica data set for a replica virtual machine 302 to back up a primary data set for a primary virtual machine 304. The data storage 250 may preserve a test point in time 322 in the replica data set using a test differencing disk 344. A processor 220 may execute a test virtual machine 342 that performs a test operation on the test point in time 322 while the replica data set continues to replicate the primary data set.

    摘要： A key protector for a storage volume is created by generating an intermediate key and protecting, based at least in part on a public/private key pair, the intermediate key. A volume master key for encrypting and decrypting one or more volume encryption keys that are used to encrypt the storage volume can be encrypted in different manners, including being encrypted based at least in part on the intermediate key. A key protector for the storage volume is stored that includes both the encrypted volume master key and information indicating how to obtain the intermediate key. Subsequently, the key protector can be accessed and, based at least in part on a private key of the entity associated with the key protector, the intermediate key can be decrypted. The intermediate key can then be used to decrypt the volume master key.

    摘要： Systems and methods for presenting multiple assets in an interactive media guidance application are provided. A guidance display containing media guidance application listings is provided, where non-linear media assets are extracted from the media guidance application listings and the guidance display is divided into different portions to present media guidance application listings of non-on-demand media assets and non-linear media assets. One portion of the guidance display may include media guidance application listings of non-on-demand assets and may indicate the non-linear media assets extracted from the portion of the guidance display. Another portion may include media guidance application listings of non-linear media assets that were extracted from the media guidance application listings. This portion may also include additional non-linear assets that are available for retrieval and playback.

    摘要： Techniques involving replication of storage are described. A representative technique includes apparatuses and methods for receiving replicated virtual storage of a replicated virtual machine, including at least a replicated base virtual disk that substantially corresponds to a primary base virtual disk to be replicated. Copies of differencing disks or other forms of virtual storage updates are received at a recovery site, each of the differencing disks being associated with the primary base virtual disk as descendents thereof. The received copies of the differencing disks are arranged relative to the replicated base virtual disk corresponding to the manner in which the differencing disks were arranged relative to the primary base virtual disk, thereby maintaining the data view of the replicated virtual machine in synchronization with the virtual machine at the primary site.
