With respect to e-mail, it is stored in a compressed and indexed format to reduce storage requirements and allow for rapid, complex searches. (This also can be done for blogs, social media, or other applications.) Archiving of real-time applications like e-mail can be deemed reliable with record integrity only if it is performed immediately, in real time.
The managed activities, methods, standards and technologies used to provide long-term, error-free storage of digital information, with means for retrieval and interpretation, for the entire time span the information is required to be retained.
