Requirement 1: Need To Save All Types Of Data
The most common question asked: What electronic documents and data need to be saved? Only "official records," or documents, files, e-mail, instant messages? The answer to all of these is at various times: yes. Both regulators and especially the courts are expecting organizations to produce (hence have preserved or saved) a wide range of documents. All types of "electronically stored information" (commonly abbreviated ESI) are discoverable. It is important to note that from a regulatory or legal perspective, there is little discrimination of a document based on its medium.
These business and legal drivers create some clear archival requirements IT can follow:
Archiving systems need to be flexible and capable to handle many types of document media - Storage systems used for archiving need to be capable of handling a variety of electronic documents media, including e-mail, instant messages, files, etc
Archiving systems need to be capable of capturing both "official" records as well as "unofficial" documents - Archiving systems need the flexibility to handle input not only from official record and document retention systems, but also electronically stored information from a number of other systems."
