11.1 ETERNUS CS800 Replication Overview
4. Enable replication for the new share or partition (see "Enabling Replication For a Share or
Partition" on page 374).
5. Before writing any data to the new share or partition, replicate the new share or partition
(see "Replicating a Share or Partition" on page 377
Fujitsu Technology Solutions recommends that you always replicate a new share or
partition immediately after creating it.
This establishes the initial data structure on the target system and greatly increases the
speed of the first replication.
6. Choose one of the following methods to regularly replicate the new share or partition:
l (Recommended) Use the Scheduler page to set up a schedule for performing
replication automatically after backups complete (see "Scheduling a Share or
Partition for Replication" on page 290).
l Manually perform replication at frequent intervals (see "Replicating a Share or
Partition" on page 377).
After replication, a snapshot is sent to the target system. You can use the snapshot to
recover the replicated share or partition on the target system (see "Task Overview:
Recovering a Replicated Share or Partition" on page 369) or restore the share or partition to
its original location on the source system (see "Task Overview: Performing a Share or
Partition Failback" on page 370).
CAUTION!
If you do not configure a replication schedule or manually replicate the share or partition
on a regular basis, your data is not protected. While the ETERNUS CS800 continually
sends data to the target system in the background to optimize the replication process,
a snapshot that preserves the complete structure of your data is sent to the target
system only when a scheduled or manual replication job occurs. If you do not regularly
and frequently replicate your data as described in Step above, it cannot be restored at a
later time.
To limit the amount of network bandwidth used for replication, enable a constant
throttle (see "Enabling System Throttling" on page 276), or schedule replication
throttling (see "Scheduling Replication Throttling" on page 291).
