FlashCopy® is a function of the IBM® System Storage® server. FlashCopy provides a fast point in time copy of the data, which can be brought online on a separate partition or system. This copy can be used for offline backups or for populating data to a development or test system. FlashCopy can be used with any of the other data resiliency technologies included in PowerHA®, or can be used separately.

Characteristics of FlashCopy
  • IBM System Storage server technology, which is integrated within the PowerHA framework.
  • Provides a fast point in time copy for use in offline backups.
  • Not a high availability technology by itself since it is a point in time copy.
  • Requires extra disk storage to create the copy on the same storage server as the source copy.
