11.1 ETERNUS CS800 Replication Overview
4. Enable replication for the new share or partition (see
Partition" on page
5. Before writing any data to the new share or partition, replicate the new share or partition
(see
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

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
Recovering a Replicated Share or Partition" on page
its original location on the source system (see
Partition Failback" on page
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
