Able to more effectively simulate varied operatinghardware environments for easy migration from legacy systems.
Backups to S3 - Using the...

environmental conditions such as temperature, or age. This means that
high disk utilization or age of the disk have no significant impact on
the probability that it will fail. .. the expected remaining time until the next disk failure grows with the time it has been since the last failure... They did find a strong correlation
