By Mike Karp It has been said (by me, in a philosophical moment early in the morning on New Year's Day) that "life is a series of accommodations." Never mind what caused that sentiment: at least in the data center, that is probably a truism. The second worst of these data center accommodations is probably the process forced upon us when we realize that backups are not going to be completed during the prescribed backup window. We then have to make what often is a no-win decision: continue with the backup (thus running beyond the allotted window, and probably degrading performance on production systems) or stop the backup process when the backup window closes (leaving what may be business critical data at risk of being unrecoverable). The worst scenario, however, occurs when we have to decide just how fast a recovery we have to be prepared to do on our data. We talked two weeks ago about understanding the types of data on our systems, the idea being that with that intelligence we could do some intelligent decision making prior to going into the backup. At that point we discussed the usefulness of flagging some file types (MP3, for example) as not worthy of being backed up. Hopefully, by identifying such files we would make a first step toward reducing the sheer volume of backed up data. Many enterprises have a method of classifying data not based on file type, but rather on some other measure. Most useful among these is a metric that looks at data in terms of its criticality to business continuance. This ought to be a measure with a much more useful focus than just knowing about the file extension. Broadly speaking (and with apologies to existential psychologist Abraham Maslow), such a system looks at data on a disk as falling into one of four categories: * Mission-critical information (the equivalent of "air" - you can't live without it). * Business-critical information (think of this as "water" - you can only go without it for a very short period of time). * Non-critical information ("food" - you can go without it, but not for long). * "Unclassified data" (probably mostly junk food, but you don't really know). What goes into these classifications will vary between sites, as will the Recovery Time Objectives (RTOs). In some cases, the RTO for mission-critical data may be as long as several minutes, while in others (particularly those relying on e- commerce) the situation may be seen as life threatening after a few seconds. _______________________________________________________________ To contact Mike Karp: Mike Karp is senior analyst with Enterprise Management Associates (http://www.enterprisemanagement.com) in Boulder, Colo., an analyst and market research firm focusing exclusively on enterprise management.
