Which data-protection policy moves data that is no longer used to a separate storage device for long-term maintenance?

The concept of data archiving is essential in data protection policies, particularly for organizations that manage large volumes of data. Data archiving specifically refers to the practice of moving data that is infrequently accessed or no longer actively used to a separate storage solution designated for long-term preservation. This is crucial because it helps preserve important information while simultaneously freeing up resources and storage capacity on primary systems.

By transferring less frequently used data into an archive, organizations can enhance the performance of their operational systems and ensure that they have a systematic approach to maintain data in compliance with relevant regulations and standards. Archived data is still retained and can be retrieved if necessary, which is especially important for legal compliance, audits, and historical data analysis.

In contrast, other options address different aspects of data management. For example, data retention pertains to establishing guidelines on how long data should be kept but does not inherently involve moving data to separate storage. Data classification involves categorizing data based on its sensitivity and importance, while data deletion pertains to the permanent removal of data, which does not align with long-term maintenance objectives. Thus, data archiving is the most accurate choice for the policy that addresses the long-term maintenance of infrequently accessed data.
