7. As soon as reverse replication has completed for each slot, the data may be recovered to the host using the original backup application. 8. New backups can now run to the Source Appliance and replication will run normally without further configuration. Figure 9 Reverse replication process: source lost . Promoting a Target Library over the WAN using iSCSI The remote site has lost both the host servers and the StoreOnce system. New server hardware has been purchased and installed and the admin now wants to recover data to the server. The admin has not installed a new StoreOnce Backup System and is going to recover data directly to the server from the Data Center StoreOnce Backup System over the WAN (which will take a long time). NOTE: The procedure described below retains the ability to back up to the Target Library. If this is not required, a simpler solution may be to make the Target Library visible (but read-only), see "Backup applications and Replication Target libraries" on page 22.
