Non-Deduplicated Replication - HP 12000 Design Manual

8 Non-deduplicated Replication

If you have not enabled Accelerated deduplication on your VLS device , non-deduplicated replication
can still provide a more reliable method of sending mission-critical data off-site compared to off-site
using physical tape (because there is no need to load/unload physical media and ship it to the
off-site location).
VLS-to-VLS non-deduplicated replication options:
Using SAN-based Automigration
Automigration also supports using a VLS as a destination library, as a device-to-device
replication scheme over an extended SAN. To use a VLS as a destination library, designate
one VLS as the source and a second VLS as the destination. The destination VLS is presented
over an extended SAN so that it is visible to the source VLS. With Command View VLS,
establishe an automigration policy and echo copy pools in the same way you set up
automigration with a physical destination library. See
Policy. The source VLS performs normal backups during your regular backup window. During
the automigration window you defined, source virtual cartridges automatically migrate to
matching virtual cartridges on the destination VLS.
The VLS with the source library must support automigration; however, it is not necessary for
the destination VLS to do so. If you have an earlier generation VLS system and you purchase
a VLS6200, VLS6600, or VLS12000 Gateway, you can use the newer models to handle
automigration as the source device. Earlier generation VLS devices can be used as destinations.
NOTE:
storage ports are wired into its private SAN and cannot be connected to a public SAN.

Using TCP/IP-based non-deduplicated replication
You can configure an echo copy pool to a LAN/WAN destination library (which connects to
a replication target on the target device). This provides an echo copy replication link over
TCP/IP between the source and destination devices.
◦ You must be running VLS firmware version 2.3 on both the source and target VLS devices.
◦ This option only supports one replication link (node0 external LAN connection).
◦ The process to set up the non-deduplicated replication is very similar to the
deduplication-enabled replication (see
initialization step because the data is transferred in its entirety every time.
You cannot use device-to-device replication with the VLS9000 because its back-end
