If your desire is to be able to restore lost data at will, the best way to go about it is to set a goal, and measure...
your performance against it. At least, that's what a recent survey of 235 storage professionals by analyst firm The Taneja Group, based in Hopkinton, MA, suggests.
The study, called "Next Generation Backup and Recovery Solutions: A Study of Customer Requirements," found that among sites that employ "restore metrics"--measuring how fast/successfully they restore data--95% were able to restore their data more than half the time, with 82% reporting success more than 75% of the time.
Despite that, only 23% of respondents have restore metrics in place to determine whether they meet service levels requirements, compared to 65% that don't. Another 12% were not even aware that restore metrics exist.
That led The Taneja Group to conclude in their report: "Going forward, we believe a strong requirement exists for these types of metrics to be automated and integrated into the leading backup software packages to ultimately support more structured--and successful--restore processes."
