According to the Exchange 2013 Server Role Requirements Calculator, single item recovery must be enabled for Native Recovery to be an option.<br />
If we have a DAG with the 3 required copies and a lagged copy located in a second data center, isn't that enough for protection, since we expect to only be able to recover an entire database? We have another solution in place for single item, a message archival appliance.<br />
We are trying to get the required amount of disk space to a reasonable amount and eliminating the single item recovery option helps.<br />
In the calculator, unless we select single item recovery, we get an alert on the Native Backup option. Can that be safely ignored?<br />
<br />
Thanks for input on this. The calculator seems to want things its way only :-)

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.

IT Administration is the processes and best practices for programming and development, and incorporates methodologies for managing activities and projects. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, extreme programming and various types of agile methodology. The life-cycle "model" is a more general term for a category of methodologies, and a software development "process" a more specific term to refer to a specific process chosen by a specific organization.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
