3 Backup Solution Design Considerations

This section uses use models to explores many of the concepts you must consider when designing
your system. Use models are organizational schemes that provide a basic organizational framework
that you can use to delineate your environment and visualize how to implement the VLS or D2D for
your best results. You might also think of the use models as decision trees in which each branch
junction is a decision point that comes with value judgments and trade-offs. The decisions you make
lead to an implementation plan.
The choices you make are economic as well as functional. Different implementations can have different
direct costs such as investment in licensing or equipment purchase/usage, and indirect costs such as
investment in maintenance or configuration. You need to balance time, money, and use policies
against one another. As with the major categories (tape, VT/D2D, clone), there is no one size fits all
solution. The optimum solution will be a balance of the models.

Analyze the Existing Environment

Carefully consider your environment in general, and your topology. Think about what you have, how
you use it, and most importantly, what you want to optimize or improve. Determine your goals for
your environment.

Consider How you Want to Back Up your Data to the VLS or D2D

• Identify the data that you want to backup to the VLS or D2D. For example:
• Data that needs a better service level than going directly to tape but does not need the highest
service level (split mirror, for example).
• Slow servers in your current backup topology. Supported topologies include SAN or LAN/SAN
