Disk-to-disk (D2D) or disk-to-disk-to-tape (D2D2T) backup architectures are rapidly gaining acceptance by IT organizations constrained by their reliance on tape-based backup and restore.
To better understand real-world D2D issues, InfoStor asked several integrators, resellers, and end users to share their experiences implementing disk-based backup. A common picture began to emerge.
Clearing up customer misconceptions about D2D is often the first line of business for many VARs and integrators.
"End users tend to think that D2D will automatically solve their backup performance problems," says Rich Baldwin, chief executive officer of San Diego-based Nth Generation, a storage-related consulting firm and solutions provider. "They think, 'If you want to go fast, just go disk-to-disk.' "
Not always true. Throughput can be impacted by a variety of factors that may still exist after disk-based backup is introduced. CEO Tom Mumford of Auburn, MA-based solution provider TriAxis puts it this way: "Speed is a function of the infrastructure in addition to the software." Mumford has helped implement a variety of disk-based backup architectures for customers, including virtual tape libraries from vendors such as Diligent Technologies.
