The IBM® Lotus® Domino® attachment and object service (DAOS) in release 8.5 reduces the total cost of ownership and helps customers with green computing practices by storing all file attachments in a separate repository on the server and retrieving them by reference. In databases that use DAOS, Lotus Domino no longer saves a separate and complete copy of every document attachment. Instead, the server saves a reference to each attached file in an internal repository, and it refers to the same file from multiple documents in one or more databases on the same server. When an attached file is large and a message containing it is broadcast to thousands of users, creating a separate copy of the message for each recipient could require several gigabytes of disk space. Multiple copies of the same attachment often also proliferated in mail threads with multiple replies. With DAOS enabled, disk space usage is substantially reduced.
