Object-based backup--an emerging field of storage technology that only a handful of companies are focusing on--introduces a new medium for data protection and retention. It presents a software infrastructure that reinvents the way we think about and visualize production data backup and archive activities. And it just may be the foundation for a strategy to use inexpensive commodity servers, disk arrays and IP networking far more effectively. An object-based system can determine if any changes to a file or its attributes have occurred since it was last backed up. If modifications are detected, only the changes are backed up--not the entire file.
