Document storage is space devoted to keeping files. This differs from archive storage where records are kept for their historical value.
Document storage applies to keeping files just in case the data contained on them needs to be recalled. When documents are stored away from the main business activity it is known as offsite document storage. It is increasingly common for organisations to outsource their document storage to a third party specialist who has the secure space, expertise, and IT needed for efficient document management. The terms document storage, records management and archive storage are interchangeable.
