System for backing up files from disk volumes on multiple nodes of a computer network

摘要: A system for backing up files from disk volumes on multiple nodes of a computer network to common random-access backup storage means. As part the process, duplicate (or portions files) may be identified across nodes, so that only single copy contents thereof) is stored in For each operation after initial particular volume, those which have changed since previous are actually read volume and In addition, differences between file its version computed changes need written All these enhancements significantly reduce both amount bandwidth required performing backup. Even when data shared-file server, privacy can maintained by encrypting using key generated fingerprint contents, users who able produce encryption access contents. To view or restore backup, user mount set as with directory structure identical entire original at time
