Chapter 6: DXi4701 Replication
Performing Data Replication

3 On the source system, create a new share or partition with
deduplication enabled (see Adding a NAS Share on page 207 or
Adding a VTL Partition on page 224).
4 Enable replication for the new share or partition (see Enabling
Replication For a Share or Partition on page 126).
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 130
Quantum 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:
• (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 297).
• Manually perform replication at frequent intervals (see
Replicating a Share or Partition on page 130).
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 121) 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 122).
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 DXi4701 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 6 above, it cannot be restored at a later
time.
