11.1 ETERNUS CS800 Replication Overview
Performing Data Replication
The Replication page allows you to set up replication for NAS shares or VTL partitions and
to replicate and recover data.
To access the Replication page, click the Replication menu.
The Replication page contains the following tabs:
l "Replication Send" on page 347
l "Receive NAS" on page 356
l "Receive VTL" on page 367
l "Actions" on page 377
l "Reports" on page 380
Task Overview
Use the ETERNUS CS800 data replication features to perform the following tasks:
l Replicate all data on a share or partition to another system where it can be recovered
at a later time (see "Task Overview: Setting Up and Performing Replication" on page
344).
l Automatically replicate files or cartridges to another system where they are
immediately available (see "Task Overview: Setting Up and Performing Directory/File

Task Overview: Setting Up and Performing Replication
To replicate all data on a NAS share or VTL partition from a source system to a target
system:
1. On the target system, add the source system to the list of allowed replication sources
(see "Adding a Replication Source" on page 259).
2. On the source system, specify the target system that will receive replicated data (see
"Adding a Replication Target" on page 253).
3. On the source system, create a new share or partition with deduplication enabled (see
"Adding a NAS Share" on page 190 or "Adding a VTL Partition" on page 206).
4. Enable replication for the new share or partition (see "Enabling Replication For a
Share or Partition" on page 350).
