Abstract: A hydrofoil includes a body, an even number of wings disposed at the opposite sides of the body and an even number of floats disposed at both sides of a bottom of the body. Each float is a hollow and flat structure. At a rear edge of the float portion is provided a float propeller. With the design of the float structure, the counterforce caused by the water waves impacting on the floats can be reduced, so that the float can move more stably to improve safety and comfortableness.

Abstract: A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes using a directory to identify keys in a key value database, walking through each identified key to identify values, identifying a file based on the walk through, and restoring the identified file to a storage device.

Abstract: A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes taking a snapshot of a virtual machine, parsing the virtual machine to determine a header section and a file system, indexing the virtual machine based on the parsing, storing the index in a storage device, and storing the snapshot in a deduplicated data storage device.

Abstract: A method, article of manufacture, and apparatus for protecting data. This includes identifying files from a master file table, generate a key/value database based on the identified files, wherein the key includes directory information and the value includes file metadata, and storing the key/value database in a storage device. Identifying files from a master file table includes parsing a VMDK to isolate a master file table region.

Abstract: Techniques for virtual machine incremental backup are described herein. According to one embodiment, a request for an incremental backing up a virtual machine (VM) is received at a storage system, the request identifying a requested VM disk image associated with a consistent state of the VM. The storage system determines a difference between the requested VM disk image and a previous VM disk image representing a previous VM backup. The changes between the requested VM disk image and a previous VM disk image are then transmitted to a target backup storage system.

Abstract: Techniques for virtual machine full backup are described herein. According to one embodiment, in response to a request to back up a virtual machine (VM) of a client, a request of VM backup is sent out. A consistent state of the VM is then identified via a VM application program interface (VM API). Subsequently a request is sent to a storage system associated with the client to ask for VM disk image associated with the consistent state of the VM to a target backup storage system.

Abstract: A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes creating a copy of a backup virtual machine on a deduplicated data storage device, registering the copy with a virtual environment manager, operating a virtual machine based on the copy and storing changes made during operation of the virtual machine to the copy.

Abstract: Searching data is disclosed. A searchable index is used to determine which, if any, data objects comprising a set of backup data are responsive to a search query. For the search query, a search result is generated. The search result includes, in the event a first data object that is responsive to the search query comprises a version of one or more other data objects that are responsive to the search query, data indicating that the first data object comprises a version of said one or more other data objects.

Abstract: A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes receiving a changed block, reading a previous backup to get a file list in change block tracking, checking a file in a modified master file table list for a reference flag, wherein the modified master file table list is based on the changed block, and modifying a database entry based on the reference flag.

Abstract: Monoclonal antibodies against LRP6 and that block the Wnt signaling pathway are disclosed. Methods of production and use thereof are also disclosed.

Abstract: Information management is disclosed. A file output from an application to an operating system is intercepted before the file output arrives at the operating system. The file output is directed towards protected data. The intercepted file output is analyzed to determine whether a predetermined type of version of the protected data has been created. In the event it is determined that the predetermined type of version of the protected data has been created at least in part because the analyzed intercepted file output includes a modification to the protected data, the protected data automatically backed up, including by storing at least a portion of the file output as a backup version of the protected data. In the event it is determined that the predetermined type of version of the protected data has not been created, the protected data is not backed up.
