Implementing an incremental backup scheme is most appropriate when there is limited media capacity. Incremental backups only capture the data that has changed since the last backup, which significantly reduces the amount of data being backed up at any one time. This is particularly beneficial when storage resources are constrained, as it allows for efficient use of available space.

Moreover, with incremental backups, you can maintain a comprehensive backup strategy while effectively managing limited storage. Each incremental backup takes up less space compared to full backups, allowing organizations to store more backup data within the constraints of their media capacity. This method ensures that as you continue to back up over time, you're utilizing the available storage efficiently while still being able to restore data effectively when needed.

In contrast, other scenarios presented, such as having limited recovery time or a preference for online disk-based media, may favor different backup strategies. However, they do not specifically address media capacity constraints as closely as the choice regarding limited media capacity does.
