Which of the following best describes the function of eDiscovery?

eDiscovery, or electronic discovery, involves the process of identifying, collecting, and reviewing electronic data that can be used as evidence in legal cases or investigations. The primary function of eDiscovery is to retrieve relevant data from vast quantities of stored electronic information, which may include emails, documents, and other digital content. This process is crucial for organizations facing legal inquiries, as it ensures that they can locate and present the necessary information in a compliant manner.

In contrast, data backup refers to creating copies of data to restore it in case of loss, while data archiving involves moving data that is no longer actively used to a separate storage for long-term retention. Data indexing relates to creating a structure or an organized framework to facilitate quick searches and retrieval of data, but it is not the main focus of eDiscovery. Given this understanding, the option reflecting the retrieval of electronic data is indeed the best fit for describing the main function of eDiscovery.
