Direct backup extends the benefits of HP’s ZDB solution by moving data directly from disk to tape and making the load on the backup server negligible or even making the backup server optional.
It minimizes the impact on database production servers by using
Additionally, the direct backup solution is fully integrated with the

What does it mean to make a direct backup? This backup solution is “serverless,” meaning that it does not use a dedicated backup server to move data and data is not moved across the LAN. The data moves directly from the client system to be backed up to a tape device without moving data through a backup server.
Direct backup supports backup of application data files and control files and of disk images
Direct backup uses existing
•access application data with minimal impact to the application - there is minimal utilization of the application server (providing little to no application down time)
•move data without encountering bottlenecks associated with network traffic and LAN speed.
In order to support direct/serverless backups, Data Protector also incorporates new technology to resolve target file systems and move data across the SAN. This new technology, based on the XCopy standard, provides a method for moving data from the target system to the tape device without moving data through a server. For a brief explanation of XCopy, see “About XCopy” on page 247.
This direct disk to tape data path (over SAN) helps to lower the need for equipment investment and boost the utilization of existing equipment.
