Figure 13-11 shows how data is generically processed on tape from the moment the data is backed up until it is sent to the off-site location. BACKUP IBM Tivoli Storage Manager SERVER DB or Recovery Plan File Database Backup Onsite Storage Hierarchy Copy Storage Pool Backup To offsite location Figure 13-11 Tivoli Storage Manager tape processing 13.7.4 Moving data from on-site to off-site The commands explained in this section show how to move data from onsite to off-site. Note that Tivoli Disaster Recovery Manager (see Chapter 19, "Disaster Recovery Manager" on page 589) automatically performs most of the tape movement operations described here, reducing the need for generating, testing, and maintaining separate scripts. For standalone tape drives (known as manual libraries in Tivoli Storage Manager),, Tivoli Storage Manager sends messages to request that volumes be mounted when they are needed. When Tivoli Storage Manager needs to write to a tape, it first tries to write to a previously used tape in the storage pool with enough room for new data (within the restrictions of collocation, if enabled). If that is not possible, Tivoli Storage Manager asks to mount a SCRATCH (unused) tape for use. In manual libraries, there is no inventory, that is, the command query Chapter 13. Routine tasks 433
