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 hardware-based
mirroring technologies rather than intrusive software-based snapshots.

Additionally, the direct backup solution is fully integrated with the industry-standard
XCopy (ANSI T10 SCP-2 Extended Copy Standard) command embedded in HP
StorageWorks tape libraries (as well as external fiber channel SCSI bridges), removing
the need for a separate “data mover” appliance.

Direct backup
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 -- either raw disk or raw logical volume.

Direct backup uses existing split-mirror and Storage Area Network (SAN) technology
to:
to:
•
access application data with minimal impact to the application - there is minimal
utilization of the application server (providing little to no application down time)

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 “
