Compressed Replication

The compressed replication feature improves performance when replicating compressible
data between source and target sites that have limited bandwidth. Before a replication stream
is sent to the target, it is automatically compressed at a rate based on current CPU utilization
and network I/O throughput. The replication stream is then decompressed when received by
the target appliance. If any part of the data is not compressible, that portion will be sent as if
compression were disabled.
All replication streams will be compressed, unless you explicitly disable compression. If your
WAN equipment provides compression, for example through a WAN accelerator, disable the
compression feature by following the procedure Disabling Replication Compression BUI, CLI.
The source and target appliances require software version 2013.1.4.0 (or later) to support
replication compression. If the target has an earlier version, a warning icon
to the target name. You will need to update the target appliance to the minimum version.
You can view replication performance statistics on the source appliance, under the progress bar
for the replication.
Description
Read-only property describing the number of bytes sent to the target.
Read-only property describing the estimated size of the data to be replicated.
Read-only property describing the estimated time remaining until
completion.
Read-only property describing the average replication throughput.
Read-only property describing whether the action is currently idle, sending
an update, or cancelling an update.
Read-only property describing the last time an update was successfully sent.
This value may be unknown if the system has not sent a successful update
since boot.
Read-only property describing the last time an update was attempted. This
value may be unknown if the system has not attempted to send an update
since boot.
Read-only property describing when the next attempt will be made. This
value could be a date (for a scheduled update), manual,or continuous.
