Advances in Backup Technology
In the past, IT organizations have turned to mainframes as a solution for high-speed backup of large databases. While UNIX systems typically delivered backup throughput of 50 to 70 Gbyte/hr, mainframes with their high-speed tape drives had a throughput nearly six times faster. However, several recent developments have turned the tables on this equation by enabling sustained backup rates of more than 1 Tbyte/hr on Sun servers while at the same time decreasing the intrusiveness of backup operations. Some of these recent developments are described in the following sections.
Faster Throughput Rates
Tape drive technology has seen dramatic improvements in throughput rates. The Mammoth 8 mm drive provides a native transfer ...
