Abstract: The present invention relates to a fibre for purification of liquids comprising a matrix of polymer with organosilane impregnated therein and a method for preparing the same. The fibre of the present invention is capable of providing at least 2 log reduction of viruses, bacteria and cysts and flux of 10 to 1000 litre per square meter per hour at 2 psig.

Abstract: The present invention relates to a fabric for purification of water. An object of the present invention is to provide a fabric for purification of liquids which achieves at least 2 log reductions of bacteria, and viruses. It is a further object of the present invention to provide a fabric for purification of liquids which provides high flow rates in gravity fed water purification systems. The present inventors have surprisingly found that a fabric having a matrix of polymer impregnated with organosilane superimposed on a surface of the fibre of a fibrous support not only provides reduction of viruses from a liquid to be purified at low pressure drops but also removes bacteria without using a separate microfiltration membrane and also retains high flow rates.

Abstract: The disclosed computer-implemented method for backing up heterogeneous virtual environments may include (1) identifying a request to back up a virtual machine executing on a host system, (2) creating a storage map of a virtual storage environment of the virtual machine by (a) identifying, from the host system, a virtual disk file that stores data for the virtual machine and (b) identifying, from a guest system operating within the virtual machine, one or more virtual storage devices that store data for the virtual machine, and (3) creating a unified backup of the virtual machine based on the storage map of the virtual storage environment by coordinating a backup operation of the virtual disk file with a backup operation of the virtual storage device. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A virtual machine may use a first one or more volumes in which one or more virtual disk image files are stored. The virtual machine may also use data stored in a second one or more volumes, where the virtual machine is configured to bypass a hypervisor to access the second one or more volumes. A time consistent backup of the virtual machine, including both the virtual disk image files of the first one or more volumes and the data of the second one or more volumes, may be created.

Abstract: Systems and methods for computer system data backup. A computer system includes an application server operating on a first host and a backup application configured to create new target database images for a sequence of backup datasets. The backup datasets include data from source databases associated with the application server. At least one of the source databases is hosted on a remote source host separate from the first host. The computer system includes a client registered with the application server and installed on a backup host. The client stores a seed document in each of the new target database images and modifies each seed document to specify which portions of a backup dataset in the sequence are to be stored in each new target database image. The backup application updates each new target database image based on the contents of a seed document.
