  • Patent number: 11228647
    Abstract: According to various embodiments, systems and methods are provided that relate to shared access to Storage Area Networks (SAN) devices. In one embodiment, a Storage Area Network (SAN) host is provided, comprising: a server component: a first host bus adapter configured to be connected to a SAN client over a first SAN; a second host bus adapter configured to be connected to a SAN storage device over a second SAN; and wherein the server component is configured to manage a data block on the SAN storage device, receive a storage operation request from the SAN client through the first host bus adapter, and in response to the storage operation request, perform a storage operation on the data block, the storage operation being performed over the second SAN through the second host bus adapter.

  • Patent number: 10089193
    Abstract: Systems and methods are provided which perform a file level restore by utilizing existing operating system components (e.g., file system drivers) that are natively installed on the target computing device. These components can be used to mount and/or interpret a secondary copy of the file system. For instance, the system can instantiate an interface object (e.g., a device node such as a pseudo device, device file or special file) on the target client which includes file system metadata corresponding to the backed up version of the file system. The interface provides a mechanism for the operating system to mount the secondary copy and perform file level access on the secondary copy, e.g., to restore one or more selected files.
