Some environments where I've performed backup assessments have had servers that have gone several days--even as much as a month--without a successful full or incremental backup; and the larger the environment, the greater the problem. At one customer's site where they back up 10,000 systems, more than 1,000 systems went four days or more without a successful backup of any kind. Servers that go several days without a backup are obviously at greater risk than others. If a backup administrator was aware of such a trend, they might do a number of things, such as cancel less important backups so that the server that hasn't backed up for several days can be given more resources.

Most backup products don't provide the kind of tools necessary in their base product to see this kind of information. The solution is a relatively simple one, but not an inexpensive one: Buy a data protection management tool.
