Smaller backups will execute faster, resulting in a shorter backup window, less drive wear, and lower media usage (and lower media costs). Most backup software... More...

FAQ's
Are there any instances where data deduplication will not provide any benefits? Superior benefits?
of new images being created, then you'll see very little benefit from data deduplication. In that case, you're better off just running differential or incremental backups.

As far as areas in which data deduplication can provide superior benefits, databases have a lot of redundant data and deduplication can have... More...

What type of data reduction ratios should you realistically expect using deduplication?
There are two ways you can look at it. Most people are looking at data deduplication in conjunction with backup; backup appliances performing deduplication or even virtual tape libraries (VTL). So, looking at it in that context, you'll hear advertised ratios of anywhere from 10 to 500X.

But, realistically, I think it's... More...

What are the benefits of using a virtual tape library (VTL) for data deduplication?
Well, there are a few big use cases right now that are driving data deduplication to the forefront of the decision-making that's going on in backup environments. The bottom line is data deduplication is dramatically changing the economics of using disk as a backup target as opposed to tape. You can only buy so... More...
