A system is described for backing-up a client device to a server using space-optimized snapshots. A snapshot is captured on the client device. The system determines which files of the snapshot are required to be uploaded to perform a backup. Thereafter, the system monitors the required files (and not other files) for write commands and directs write operations for the required files to be performed copy-on-write. After a required file is uploaded, the system stops monitoring the file and any copy-on-write data that may have been generated for the file is removed from the snapshot to conserve space. The process continues until all required files are uploaded.

Space optimized snapshot for network backup

Distributing an update from a server to multiple endpoint devices that reside on the same local network. The server provides information to each client device identifying all other devices located on the same local network that will also need to receive the update. Each client device sorts the files and begins the process of downloading the files by checking, for each file in sequence, whether another device on the same network has downloaded the file or is currently in the process of downloading. If another device on the same network has completed downloading the file, the device requests the file from the other client device. If another device is currently in the process of downloading, the device places the file at the end of the sequence. If the file has not been downloaded and is not being downloaded, the endpoint device initiates downloading the file from the server.

Peer-to-peer network download optimization

Techniques are described for predicting the storage capacity and performance requirements for deploying and maintaining a backup solution within an enterprise. In particular, a backup system is described which uses an initial pilot phase, during which the system can gather information about the files and data on each end user's device (i.e., client device) that will be backed up and provide a more realistic estimate and resource planning for the backup solution deployment. This initial pilot phase can be performed before any content is actually backed up from the client devices.

Predicting storage capacity and performance requirements of a backup solution

A desktop image management system is described that can be used to efficiently manage desktops and desktop image data in hosted hypervisor environments. The efficiency of backing up data and otherwise managing desktops that are running on virtual machines in a hosted hypervisor environment can be improved by utilizing an image management client installed in the host operating system and individual drivers installed on each virtual machine running on the hosted hypervisor. The image management client may also simplify and improve the process of distributing software updates from the central server to target virtual machines running on the hosted hypervisor environment.
