Abstract

Storage networks and intelligent disk subsystems enable new possibilities for the backup of data. This article presents an architecture which integrates the steps for making a consistent copy of the production data using disk subsystem based snapshots (e.g., IBM FlashCopy*), continuing the application on the primary server, and backing up the copied data from a secondary server. The outlined architecture off-loads the backup data transfer from the application server to a secondary server whilst it provides support for heterogenous operating systems of the application server. The actual architectures today are inflexible because they always demand the same operating system and the same hardware for the backup system. With this the acceptance of application server free backup in the market is low because it needs to duplicate a complex infrastructure. The remarkable difference of the described approach is its flexibility and completeness. It is possible to offer application server free backup service to any other operating system with only setting up one server instance.
