Which of the following is a type of backup method for less frequently accessed data?

Archived backup is specifically designed for less frequently accessed data. This type of backup involves storing data that is not regularly in use, often moving it to a cheaper storage medium to optimize cost and resource usage. The data in an archived backup is preserved for long-term retention and can be retrieved when necessary, but it's not required for day-to-day operations.

In contrast, real-time backup focuses on continuously updating the backup as changes to the data occur, making it ideal for data that needs to be accessed immediately and frequently. Incremental backup involves saving only the data that has changed since the last backup, which is useful for efficiency but still targets operational data. Full backup, while comprehensive in covering all data at once, is not tailored to handle less frequently accessed data specifically. Thus, archived backup is best suited for this purpose, effectively managing the storage of data that isn't required on a regular basis.
