Before you start
To activate your license you must first obtain a permanent License To Use (LTU) from the HP Licensing
website and then use the Web Management Interface to apply the LTU, activate the replication
feature and complete the licensing process. The HP Licensing website will ask you for:
•
The HP entitlement order number for the HP StoreOnce Replication license (found on the
entitlement certificate)
•
Single-node systems:
The unique HP StoreOnce Backup System serial number (found on the
label on the top of the unit)
•
Multi-node systems:
The cluster ID, which can be found via the B6000 Management Interface
(GUI or CLI).
•
Standard registration information, such as name and contact details
Online LTU retrieval is the recommended method for license redemption, but there is also a License
Key Request Form that you can submit by post or fax. If you choose to complete this form instead
of redeeming your license from the HP Licensing website, please be sure to include your HP
StoreOnce Backup System serial number on the form.
NOTE:
The LTU is tied uniquely to the serial number of your HP StoreOnce hardware. If your
hardware serial number changes (by swapping out the unit motherboard), the LTU must be
transferred to the new hardware via the HP Licensing website. A new LTU is generated, which must
then be applied and activated via the Web Management Interface on the repaired/replaced
system.
Seeding the Target Appliance
All Replication status and configuration pages are available from the Replication tab on the Web
Management Interface. See the HP StoreOnce Backup System user guide for information about
using the Replication wizard to configure mappings to virtual tape devices and NAS shares.
Seeding the Replication Target Appliance
Data deduplication ensures that the amount of data to be replicated is minimized and the impact
on network traffic is negligible. However, the benefits of deduplication apply only after the first
full backup. The first synchronization of the files (NAS shares) or cartridges (virtual tape devices)
will require significant bandwidth. The same applies in reverse, if you need to recover data to a
Target from a Source. Therefore, there is an advantage to being able to accelerate the replication
of the first full backup. This process is known as seeding.
As part of the deployment strategy, it is important to decide how the first full backup will be seeded.
There are three main options:
•
This option does not use seeding, instead we simply allow the first synchronization to take
place over the WAN. If required, you may choose to limit the bandwidth available for the
replication job from the Local Settings on the Web Management Interface, see the HP StoreOnce
Backup System user guide. This could take a very long time to complete and may not complete
before the next scheduled backup to the share or slot being replicated.
•
If the Target Appliance is not yet in use, it may be possible to colocate the Source and Target
Appliances on the same site LAN to perform the initial replication locally on a high bandwidth
link and then ship the appliance to the Data Center.
•
If the Target Appliance is already in use and you have configured NAS shares, you can seed
initial data onto a Non-Replicating Share, as described below, before you use the Web
Management Interface to configure the replication source and target.

You only need to seed with one full backup.
