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:
