Active to Active example

In the following example there are again two offices, each with an HP StoreOnce Backup System.
The HP StoreOnce Backup System in Office A is being used by the host server for backup and
restore and all Replication-Source libraries and shares are being replicated to matching
Replication-Target libraries and shares on the HP StoreOnce Backup System in Office B. However,
there is also a single host backing up to six cartridges on another library on the HP StoreOnce
Backup System in Office B. Two of those cartridges are configured to replicate to a Replication-Target
library on the HP StoreOnce Backup System in Office A. A replication license is required for both
HP StoreOnce Backup Systems.

Many to One example

In the following example a company has two remote offices and a central data center. There are
small HP StoreOnce Backup Systems in each remote office which host Replication-Source Libraries
and Shares for backup from local host machines. In the data center there is a larger StoreOnce
Backup System that is used solely to host Replication-Target Libraries and Shares for the remote
offices. A replication license is required only for the HP StoreOnce Backup System in the Data
Center. That license covers all Replication-Target libraries and shares.
This is also a good example of slot mapping. Library 2 on the Target Appliance is being used as
a Replication-Target Library by Replication-Source libraries in Office A and Office B. The
Replication-Source library in Office A is replicating two slots (colored red), while the
Replication-Source library in Office B is replicating five slots (colored red).
