Supported configurations
Basic configuration: single disk array - dual host
Both hosts are connected to the same disk array, so that the I/O infrastructure of the
RAID system is actually shared between the application client 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 impact of the backup on the database performance is minimal.
Figure 83 Single disk array - dual host (full performance, Zero
Downtime Backup)
The Data Protector snapshot integrations allows automatic handling of disk array
status as well as tight integration with applications such as SAP R/3, Oracle or
Microsoft SQL or Exchange Server (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
to perform the following steps:
