The Chatter Feed can be exported by selecting the 'FeedItem' object in Data Loader. This object stores the data for all Chatter posts in an Organization.
To export the 'FeedItem' object, perform the following:
Note: If you perform a query about the Chatter FeedItems with the type of "ContentPost", this may cause Data Loader to give out an error on the Java Heap Space. The reason for this is that Data Loader does not export file attachments. To leave these FeedItem types out and to successfully export using the Data Loader, append "Type != 'ContentPost'" to the end of the query.
Select ID, CreatedById, Body FROM FeedItem WHERE LastModifiedDate > 2015-01-01T00:00:00Z AND LastModifiedDate < 2016-01-01T00:00:00Z AND Type != 'ContentPost'
If you want an export that includes the "ContentPost" types, you can Export Backup Data from Salesforce. The name for the object differs between the Data Loader and the Data Export Service, and you will want to choose the "FeedPost" object, which was replaced by "FeedItem" in the API.
For information on importing feed items using the "@username" syntax, visit the Salesforce Idea for the Ability to Mention Users in FeedItems Inserted by the Data Loader or API.
