Manage TimeFinder/Mirror sessions

TimeFinder/Mirror is a business continuity solution that allows the use of special business continuity volume (BCV) devices.

Prerequisites

  • TimeFinder/Mirror is not supported on storage systems running PowerMaxOS 10 (6079).
  • TimeFinder operations are not supported on Open Replicator control volumes on storage systems running HYPERMAX OS 5977 or PowerMaxOS 5978.

About this task

Copies of data from a standard device (which are online for regular I/O operations from the host) are sent and stored on BCV devices to mirror the primary data. Uses for the BCV copies can include backup, restore, decision support, and applications testing. Each BCV device has its own host address, and is configured as a stand-alone device.

The TimeFinder/Mirror dashboard provides you with a single place to monitor and manage TimeFinder/Mirror sessions on a storage system.
