Are you backing up too much data? According to Jon Toigo, of Toigo Partners International, you probably are.
In this segment from his Storage Decisions presentation, Toigo explains that making some effort to categorize data can make for an efficient DR program and free up storage space by junking data that is no longer needed.
Instead, many organizations take the “backup everything” approach, Toigo said.
“That is avoiding the problem; that is sidestepping the key problem. The key challenge of disaster recovery is sorting through the junk drawer of storage and figuring out what data belongs to what mission-critical applications, so that I can backup that data,” Toigo said. “So I can apply the most high-availability strategy to data that belongs to always-on applications: Applications that absolutely must not stop.”
Toigo said an analysis of 3,000 businesses found that only 30% of the data stored on disk is needed for day-to-day business, while another 40% isn’t used daily, but has to be retained.
He said that storage costs account for between 33% to 70% of spending on IT hardware, and much of the data stored isn’t mission-critical information. He said that organizations need to develop data classification methods that are automated and don’t require employees to perform the process.
“If we could apply a little storage resource management, a little archive, a little data hygiene, we could buy back a substantial complement of the disk capacity we already own,” said Toigo.
