Target set definitions

Edit online

IBM® Storage Protect Snapshot requires target sets to be defined for SAN Volume Controller, Storwize® family, and DS8000®. A target set contains volumes that are allocated in the same storage subsystem, and are of the same size as the volumes that contain the data to be protected. The number of target sets determines the number of backup versions that can be kept at a time.

Define targets by using target set definition files, as follows:
  • SAN Volume Controller
  • Storwize family
  • DS8000
Alternatively, use a naming convention for SAN Volume Controller and Storwize family only. This convention determines the name of the target for both the source volume name and the target set name as specified for the current operation.
Tip: There is no requirement to define target volumes, if you select SAN Volume Controller and Storwize family dynamic target allocation.
