What must be true for logs to be retained beyond the standard pickup duration?

For logs to be retained beyond the standard pickup duration, they must have been modified in the last week. This requirement ensures that only relevant and active logs are held for a longer period, aiding in efficiency and compliance. When logs are modified, it indicates that they are still pertinent to operations, whether for troubleshooting, analysis, or compliance reporting. This practice helps in managing storage effectively, ensuring that log retention policies are both optimized and aligned with operational needs.

The other options do not align with the criteria necessary for extending log retention. The frequency of modifications, the format of the logs, or categorization under specific services are not definitive factors for extending retention; rather, the focus is on the recency of modifications to ensure logs remain relevant and practical for ongoing analysis.
