153NAS 1000s Administration Guide
A
Backup Management
This appendix is a backup guide for HP StorageWorks NAS devices. This appendix guides the
reader through the process of determining which backup and restore solution is best suited to
the NAS device and their business environment.
As a source and a destination for departmental, workgroup, and enterprise data, the NAS
1000s becomes an integral part of company computing environments. Therefore, efficient
backup and reliable restore capabilities are a priority.
This appendix provides pointers for setting up and maintaining reliable backups, including:
â– Backup solutions
â– Best practices
Backup Solutions
There are three main considerations when developing a backup solution:
â– System environments
â– Hardware options
â– Software options
System Environments
In many departmental and workgroup situations, it is common to connect a tape backup device
directly to the NAS device, using a SCSI connection. In this scenario, the server has exclusive
use of the tape device. HP has several tape solutions with wide industry acceptance available
for use with the NAS 1000s.
The NAS device is deployed into a SCSI direct connect environment.
SCSI Direct Connect Environments
The NAS device may be directly connected to a large tape library using an optional SCSI tape
controller. The optional High Voltage Differential (HVD) or Low Voltage Differential (LVD)
controllers have two SCSI busses, each capable of supporting up to two DLT 7000 (35/70 GB)
devices, for a total of four tape drive devices.
