Computer file copy systems and methods in which a list of files to be transferred from storage on a source file storage computer is sorted by one or more processors of a copy computer in ascending order from a smallest file size to a largest file size. Thereafter, files having the smallest file sizes are selected from the sorted files such that a total size of the selected files is equal to or less than a total size of memory available on the copy computer, the selected files are copied concurrently with one another from storage on the source file storage computer to the available copy computer memory by the one or more processors, the files are written concurrently with one another from the memory on the copy computer to storage on a target file storage computer by the one or more processors, and the process is performed iteratively.

Computer file copy systems and methods

Methods and systems for creating and maintaining a virtual library of virtual hard disks involve one or more processors partitioning resources on a physical host computer into at least one virtual machine having at least one virtual hard disk attached to the virtual machine and loading pre-selected custom content on the virtual hard disk. Thereafter, the virtual hard disk may be detached from the virtual machine and cataloged in a database together with control parameters limiting cloning of the detached virtual hard disk. At a later time, the cataloged virtual hard disk loaded with the pre-selected custom content may be attached from the database to the virtual machine on the physical host computer.
