AWS Glacier is designed specifically for data archiving and long-term backup. It provides a low-cost storage solution that is optimized for data that is infrequently accessed but needs to be retained for long periods, such as regulatory records or historical data. The service is particularly useful for organizations that have large volumes of data that do not require immediate retrieval, allowing them to save on storage costs compared to services designed for frequent access.

When using Glacier, data retrieval does take longer, which aligns with the use case of archiving where immediate access is not necessary. This contrasts with high-speed data retrieval services, which are intended for quick access to frequently used data. Additionally, real-time data processing typically involves analyzing or processing data on the fly, which is not a function associated with Glacier, as it focuses on storage. Temporary file storage is also not what Glacier is designed for, since it serves to store data for long durations rather than short-term needs. Thus, the primary purpose of AWS Glacier as a dedicated archiving solution clearly supports the selection of this answer.
