SharePoint Server 2010
Records Management Features
Increase efficiency in your organization with a records management system in SharePoint 2010.
Every document in SharePoint Server 2010 can be assigned a unique identifier, which stays with the document even when it's archived. This allows records to easily be referenced by an ID no matter where the document moves.
File Plan Reports
You can generate status reports showing the number of items in each stage of the file plan, along with a rollup of the retention policies on each node in the plan.
Retention policies can have multiple stages, allowing you to specify the entire document lifecycle as one policy (e.g. review Contracts every year, and delete after 7 years).
