Mainframe Enablers TimeFinder SnapVX and zDP 8.5 Product Guide

A softlinked snapshot is a copy that has been processed using the targetless replication technology that allows you to perform a point-in-time copy using thin devices, without specifying a target destination device. The term “soft” means that the snapshot was created without an association to a target device. This snapshot can be linked and unlinked to multiple target devices.

All softlinked snapshots require PowerMaxOS 5978 or HYPERMAX OS 5977.

A hardlinked snapshot is a snapshot that is created with a specific source and target device.

With PowerMaxOS 5978, both softlinked and hardlinked snapshots can be created on the same device.

You can enable or disable softlinking using the SOFTLINK parameter on the GLOBAL command or the &SOFTLINK site option.
