Unisphere and Unisphere Central 2020 R1 Administrator's Guide

Change the Replication Attributes

Use the Edit Replication dialog box to change replication attributes such as bandwith control, deduplication, and whether to include active snapshot data.

1. If a Storage Center is selected from the drop-down list in Unisphere Central, click (Home).
   The Unisphere CentralHome page is displayed.
2. From the DATA MOBILITY menu, click Replications & Live Volumes.
   The Replications & Live Volumes view opens to the Replications tab.
3. Select the replication to change and click (Edit).
4. Edit any of the following settings as needed:
   • Replication Bandwidth Control—Provides a list of definitions that control bandwidth usage between the local and remote Storage Centers.
   • Replication Deduplication—When selected, copies only the changed portions of the snapshot history on the source volume, rather than all data captured in each snapshot. Deduplication saves bandwidth but is more resource intensive for the Storage Center.
   • Replicate Active Snapshot—When selected, copies all the current, unfrozen volume data on the volume. This option cannot be disabled for synchronous replication.
   • Replicate Storage To Lowest Tier:—When selected, forces all data to be written to the lowest storage tier of the target volume.
     NOTE This option is only available when the transfer type is asynchronous and only when the feature is enabled on the Data Collector.
