Word of the Day: storage snapshot

Word of the Day Daily updates on the latest technology terms |September 13, 2017

storage snapshot A storage snapshot is a set of reference markers for data at a particular point in time. A snapshot acts like a detailed table of contents, providing the user with accessible copies of data that they can roll back to. Each snapshot uses a differencing disk -- a virtual hard disk (VHD) -- that stores changes made to another virtual disk or the guest operating system. This VHD intercepts all future write operations and leaves the original data in an unaltered state. Snapshots have parent-child relationships and form a tree. Each snapshot taken creates another branch of the tree. Snapshots are generally created for data protection, but they can also be used for testing application software and data mining. A storage snapshot can be used for disaster recovery when information is lost due to human error or data corruption. Learn more...
