removable media has to be registered into the catalog/database of the media server at the data center site. 5. Create devices on the StoreOnce Backup system at the data center site using an agreed convention e.g. TVTL1, TNASshare1. Discover these devices through the backup application so that the media server at the data center site has visibility of both the removable media devices AND the devices configured on the StoreOnce Backup system. 6. Once the removable media has been imported into the media server at the data center site it can be copied onto the StoreOnce Backup system at the data center site (in the same way as before at step 2) and, in the process of copying the data , we seed the StoreOnce Backup system at the data center site. It is important to copy physical tape media into the VTL device that has been created on the StoreOnce Backup system and copy the disk target for backup device (RDX) onto the StoreOnce NAS share device that has been created on the StoreOnce Backup system at the data center site. 7. Now we have to set up the final replication mappings using our agreed naming convention. Go to the remote sites and configure replication again to the data center site, being careful to use the agreed naming convention at the data center site e.g. TVTL1, TNASshare1 etc. This time when we set up replication the StoreOnce 4220 at the target site presents a list of possible target replication devices available to the remote site. So in this example we would select TVTL1 or TNASshare1 from the drop-down list presented to remote site C when we are configuring the final replication mappings. This time when the replication starts almost all the necessary data is already seeded on the StoreOnce 4220 for Remote site A so the synchronization process happens very quickly. The media servers are likely to be permanently present at the remote sites and data center site so this is making good use of existing equipment. For physical tape drives/library connection at the various sites SAS or FC connection is required. For removable disk drives such as RDX a USB connection is the most likely connection because it is available on all servers at no extra cost. If the StoreOnce deployment is going to use StoreOnce NAS shares at source and target sites the seeding process can be simplified even further by using the portable disk drives to drag and drop backup data from the source system onto the portable disk. Then transport the portable disk to the target StoreOnce site and connect it to a server with access to the StoreOnce NAS share at the target site. Perform a drag and drop from portable disk onto the StoreOnce NAS share and this then performs the seeding for you! NOTE: Drag and drop is NOT to be used for day to day use of StoreOnce NAS devices for backup; but for seeding large volumes of sequential data this usage model is acceptable. Only HP Data Protector, Symantec NetBackup and Symantec Backup Exec support HP StoreOnce Catalyst - but Catalyst stores can be "copied" to Tape or USB Disk using object copy (DP), duplicate commands (NetBackup).
