KEY CONSIDERATION FOR BACKUP AND RECOVERY
We all know how important it is to protect the crown jewels of any business—the data. Chief among IT challenges for data protection are the ever-growing rates of data and associated volumes.
The overall objective of backup and recovery is to offer the ability to recover from any failure or data loss within a specified period of time. The process of backing up, especially to disk, is generally highly automated after initial setup across applications, platforms and virtual environments. Historically, backing data up was largely the exclusive domain of tape rather than disk. Breakthroughs in disk technologies and pricing have led to very dense arrays that are power, cost and performance efficient. This has caused a shift in the primary target of a backup or recovery from a tape library to a disk library. In fact, according to a 2010 survey by the Enterprise Strategy Group, 62 percent of organizations currently back up to disk-based storage and then to tape; 18 percent back up to disk only; 20 percent continue to back up directly to tape (source: the modernization of backup: more disk, less tape by searchstorage.com).
