Figure 11 illustrates a familiar concept in database-driven applications—that of redo logs (or
transaction logs). These logs are critical for recovering a database to a given point in time (PIT). The
logs are only needed in between full backups to roll the database forward or back to a given PIT, and
backing them up to tape can be quite a slow process. The benefits of using virtual tape include:

• It is fast.
• Its optimized storage ensures no wasted capacity.
• If necessary, the logs can be backed up more frequently, enabling better granularity for PIT restores.
