Chapter 5. Commercial Backup Utilities

Choosing a commercial backup product is hard work. There are more than 50 products with hundreds of features that change every day. Combine the complexity of the subject matter with the fact that every company’s data protection needs are different, and the result is that if two administrators of equal skill from two different companies perform an equally exhaustive search for a backup product, they will arrive at different results because of differences in their companies’ specific needs. A product that might not be a good choice for any other company might be the perfect choice for yours, simply because it does something no other product does—something that your company needs it to do.

Although there are a few products that come close, there is no single product that meets everyone’s needs. That means that neither this chapter nor this book says “pick product X” at any time. This is for a lot of reasons, not the least of which is change. The backup and recovery market changes every day. Users’ backup and recovery needs change, and what different companies do to meet those needs changes. Add to that the ever-present influence of competition. It’s happened more than once that a lesser-known backup product comes out with a new version that significantly changes its standing in the market. This constantly changing nature of the backup and recovery market means that any recommendation you read here could be wrong by the time the book hits the shelves.[29]

There are two reasons why this chapter also is not going to attempt to give you a summary description of the available backup products. The first is, as said, that the information here may be out of data by the time the book is printed. The second reason is bias. I would be lying if I said that I knew all 50+ products equally. I know certain products better than others, and those products would receive a more accurate description.

What to Look For

What information should you look for in a backup product, then? This chapter contains several sections that correspond to sections of an exhaustive Request For Information (RFI), which appears at http://www.backupcentral.com. Each section describes a particular area of backup and recovery technology. After reading the section, you should be able to understand the corresponding questions in the RFI. You then can use the RFI in a number of ways. Feel free to use it (or excerpts of it) for your own RFI from the backup vendors that you are considering. However, any vendor that wishes to may have its updated RFI response posted on the web site, http://www.backupcentral.com. This web site also will be used to cover any new areas of technology that aren’t covered in this book.

When looking at a potential backup product, there are several questions that you should be asking:

  • Does the product fully support your platforms?

  • Does the product back up raw partitions?

  • Does the product back up very large filesystems and large files?

  • Does the product back up many clients to one drive simultaneously?

  • Does the product back up one client to many drives simultaneously?

  • Does the product handle data requiring special treatment?

  • Does the product have storage management features?

  • Does the product reduce network traffic?

  • Does the product support a standard or unique backup format?

  • How easy is the product to administer?

  • How secure is the product?

  • How easily does the product perform recoveries?

  • How well does the product protect the backup catalog (database, index)?

  • How robust is the product?

  • How automated is the product?

  • Can the product verify its volumes?

  • What does the product cost?

  • What vendor is selling the product?

These issues are discussed in the following sections.



[29] Just to illustrate this point, a few years ago I really liked a particular backup product. It was a very good product that had features that other products still don’t have. The company got bought out recently, and the product no longer exists!
