Over time these windows have shrunk to near non-existence due to the globalization of business through its use of the Internet and the World Wide Web. While tape system speeds have accelerated and tape capacities have increased, they have not keep pace with the demand for shorter backup windows, quicker restoration requirements, and the rapidly escalating volume of disk drive data being backed up. At the same time, the cost of PC disk drives ("ATA" computer interface) has dropped to be competitive with tape, and disk-to-disk (D2D) backup has become popular, particularly using the new Serial ATA (SATA) PC drives. A D2D system can run at the full speed of disk, and can use the higher capacity of PC disk drives (up to 400 Gbytes today), because backup is primarily serial data... https://escholarship.org/uc/item/3kd123k8 Fri, 10 Dec 2004 00:00:00 +0000 Gordon F.
