Chalktalk video: High availability or backup?
Most data centers have some sort of backup strategy where it copies data on a periodic basis, typically once per night, to a secondary storage device and then either replicated or transported to a disaster recovery site. They count on this process to help recover from a disaster. If the disaster is local the organization may be without a particular application for a few hours. A disaster that strikes the entire data center may cause an outage lasting a number of days. For these situations organizations should look at high availability software instead of backup. In this ChalkTalk Video, Storage Switzerland and Carbonite discuss backup and high availability to help you understand the differences and assist determining which solution is best for you.
