Figure 4 Network backup
To accomplish backup of a network environment you need an application that allows
you to:
• Attach backup devices to any system in the network
This enables local backups of systems with large volumes of data and network
backups in order to reduce backup device costs.
• Route backup data flow to any network path
• Route backup data away from the LAN and onto a SAN when data volume or
network traffic makes LAN transfer inefficient
• Manage backup activities from any system
• Integrate into the IT management framework
• Support many different types of systems to be backed up
Direct backup
A direct backup is one in which you can send data directly from disk to tape in the
SAN without involving a dedicated backup server for the data movement.
The use of a filesystem-independent ability to resolve data is fully integrated with the
industry-standard XCOPY functionality that is embedded in supported disk arrays
and bridges, removing the need for a separate data mover appliance.
Data Protector architecture
The Data Protector cell, shown in Figure 5 on page 41, is a network environment
that has a Cell Manager , client systems , and devices . The Cell Manager is the central
control point where Data Protector software is installed. After installing Data Protector
software, you can add systems to be backed up. These systems become Data Protector
client systems that are part of the cell. When Data Protector backs up files, it saves
them to media in backup devices.
