What is the main focus of data preservation within storage systems?

The main focus of data preservation within storage systems is ensuring the longevity and availability of data. This concept is crucial because it emphasizes the importance of maintaining data over time so that it remains accessible and usable when needed, regardless of potential changes in technology, formats, or other factors that might affect data integrity.

Data preservation encompasses various practices such as implementing backup strategies, using redundancy, regular data integrity checks, and ensuring that data can be retrieved in the future. This focus ensures that critical, historical, or legally required information remains intact, compliant, and accessible for future users.

While the other aspects mentioned, such as eliminating obsolete data and storing data in multiple formats, may serve important roles in data management, they do not directly align with the overarching goal of preservation, which prioritizes the safeguarding and availability of data over time. Creating more storage capacity is a separate concern that deals with the physical aspects of managing data, rather than its preservation.
