Replication deployment strategies
There are many deployment strategies; the following three are perhaps the most typical:
•
Active to Passive
•
Active to Active
•
Many to One
Active to Passive example
In the following example there are 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 the shares and libraries that have been configured on it are being replicated to matching
shares and libraries on the HP StoreOnce Backup System in Office B. A replication license is
required only for the HP StoreOnce Backup System in Office B. That license covers all
Replication-Target shares and libraries on Appliance B.
