actually shared between the application client (or host) and the backup client.

As the application client and the backup client are two physically different systems,

they can use their own resources (I/O channels, CPUs, memory, etc.) for their

dedicated activities, such as backup, without interfering with each other. In this way,

the backup performance does not impact the database performance.

Figure 79 Local mirror - dual host (full performance, Zero Downtime

Backup)

The Data Protector split mirror backup integration allows automatic handling of mirror

status as well as tight integration with applications such as SAP R/3 and Oracle (to

ensure data consistency and application/database-aware backups). Only if the

application/database is aware of a backup can a secure operation be guaranteed

and native application tools be used for restore. The impact of a backup on the

application is reduced to the time needed to perform a split of the mirror and put the
