3. Create an echo copy pool (including selecting whether to use tape initialization).
On the source device, select the destination library and "Create echo copy pools." In this
context, the echo copy pool acts as an asynchronous mirror between the selected source
virtual library and the target library. The barcodes created initially on the target device are
now also "echoed" in the source virtual library.
The slot range represents the slots on the replication target (not the source virtual library).
Generally you would create an echo copy pool across all the slots in that replication target
(because there is only ever one source device linked to a replication target). If you want to
create multiple sets of replicating cartridges, for example, with different replication priorities
(see Advanced Replication Job
copy pool and another part to another echo copy pool, etc.
The option to "Initialize via Tape Transport" is selected when creating the echo copy pool
and determines whether tape initialization will be used or not. If not selected, initialization
will be performed over the LAN/WAN.
The Deduplicated vs. Non-Deduplicated option is used when you may have a VLS shared
between two different backup applications of which one of them is not currently supported by
Accelerated deduplication. In this case, you must create a separate non-deduplicated echo
copy pool for the virtual cartridges that cannot be deduplicated and thus force non-deduplicated
replication for these cartridges (otherwise these cartridges will not be replicated). This will
improve performance because the replication system will not have to attempt to perform
deduplication-enabled replication on non-deduplicated cartridges.
4. Edit the replication policy (in echo copy pool).
By default the LAN/WAN replication policy (from the source perspective) is set to replicate
24 hours per day every day of the week, and set to continue running jobs at the end of each
window. If you want to restrict the replication jobs to only run during specific hours of the day
on specific days, you can edit the default replication policy by changing the Start Day, Start
Time, Duration; the "At End of the Policy Window" can be changed to cancel replication jobs
if they have not completed within the specified replication window (they would be restarted
on the next window).
