Chapter 6: DXi8500 Replication
Performing Data Replication
170
Quantum DXi8500 User’s Guide
5
Before writing any data to the new share or partition, replicate the
new share or partition (see
Replicating a Share
on page 179 or
Replicating a Partition
on page 188).
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 358).
• Manually perform replication at frequent intervals (see
Replicating a Share
on page 179 or
Replicating a Partition
on
page 188).
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 172) 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 172).
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 DXi8500 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.
Note:
To limit the amount of network bandwidth used for replication,
enable a constant throttle (see
Replication Send
on page 309),
or schedule replication throttling (see
Scheduling Replication
Throttling
on page 359).
