One of the more critical pieces of information that organizations need as they put together a disaster recovery plan is how much data they have in their environment and how quickly it is changing. The reason this information is so important is that without it, organizations often have no way to effectively size how much or what type of capacity they need to protect and recover their production data. In fact, I was astonished at how little information this was available about this topic or the fact that there were so few good articles on the subject.
Ironically, some of the best information I found on the web on this topic was squirreled away in comments on user forums. For instance, on one forum on the Windows IT Pro web site, one administrator was looking for information on how to appropriately size the network bandwidth between his primary and secondary sites for replication. The best (and only) response that anyone provided was for the administrator to take a look at how much data his organization is incrementally backing up on a daily basis to get some sense of how much data is changing daily in his environment.
