ECG075.0997 (cont.) DLT Tape Array II ... 1993 1994 1995 1996 1997 INTRODUCTION: THE NEED FOR SPEED As companies migrate to standardized server solutions, there are significant changes in backup/recovery paradigms. The five-days-a-week, nine-hours-a-day operation has expanded to seven days a week and 24 hours a day. Backups must be performed concurrently (live) or during very small scheduled outage windows. In either case, the backup must be performed in a minimum amount of time: Speed is essential. With the size of data sets and databases approaching and exceeding the terabyte mark, customers require improved performance for large backups. The chart below illustrates typical peak server backup speeds for the last five years. Today, Compaq passes 165 gigabytes per hour (GB/hr) with off-the-shelf technology.
