Snapshot Overview - Hitachi AMS2100 User Manual

Copy-on-Write SnapShot creates virtual copies of data volumes
within the Hitachi Adaptable Modular Storage (AMS) array. These
copies can be used for recovery from logical errors. They are
identical to the original volume at the point in time they were
taken.
This guide provides instructions for planning and designing,
configuring and testing, and using and monitoring SnapShot. In
