instant copy

Instant Copies are snapshots of data sets. With Instant Copies, copies of several terabytes( TB) of data can be created in the disk subsystems in just a few seconds.

This reduces the load on the central processing unit( CPU) and the buses, but at the same time lowers performance. Instant Copies are performed virtually and are used in data backup, for test data and in data mining.

With instant copies, as with snapshots, it is important that data consistency is maintained. There are various solution alternatives that rely on one-time or continuous copy creation with on-the-fly or mirroring of the data.
