EisenVault retains a unique and complete copy of each version of each document as it is checked out and back into the Document Library. When a document is checked in and changes have been made, EisenVault automatically creates a new complete unadulterated version in the repository. Document versions are simply numbered as 1.0, 1.1, 1.2, 1.3, and so on, known as minor version and if you update a new version of any document manually system will ask you whether is it minor or major, and the major version sequence is 1.0, 2.0, 3.0, 4.0 and so on.
When viewing a list of documents (folder view, search view), only the most recent version of the document is displayed. The ‘Document Version’ column shows the number of versions of a given document in the below document action.
You can view previous versions of a file through the version history.
When a document is added to the library, it starts at version 1.0 and is “owned” by the person who added a document. As the document is modified, that number increases by 0.1, and the “Modifier” of the version changes to the person who has modified the document. For example, Paul added a file to the document management system. That file starts at version 1.0 and is owned by Paul. Sally has access to the file and decides to change the file in order to modify it with the latest report information. Sally checks the file back into the system. That file is now at version 1.1 and is modified by Sally.
Viewing Previous Versions of a Document
To view previous versions of a document, select a document and click on the number of versions link in the Version History. Click on the version preview icon in the version history and the preview of the document will show in a new tab in the browser.
