The idea behind restoring older copies of content is to revert to content at a point in the past and to reactivate it. To restore older versions you actually follow the same working principles as explained in restoring active object instances. Furthermore, it might be a good idea to first familiarize yourself with the Workbench's view mode function because this is the first you are going to need here.
Before you start, one warning: the restore of older versions of an object always removes the ongoing work on the object.
In the following example two versions 'V1' and 'V2' of the ‘Fishes’ folder in the 'Encyclopedia: Encarta' are already available. 'V2' is the active version while 'V1' is an older and hence an inactive version. Since 'V2' is also the latest object instance it is shown by default in the Workbench nodes.
The Workbench showing the latest version of the content
The latest version of the 'Fishes' folder contains the 'Versioning notes' topic and the 'The tuna' subfolder. These objects are not available in the 'V1' version The next examples demonstrate how to restore the 'V1' version of the 'Fishes' folder. The first step is to switch to the 'V1' view mode.
Switching a content object to an older version
You do this by popping up the menu of the 'Fishes' folder in the tree node and selecting 'View mode>V1'. The Workbench node will switch the folder to the 'V1' content. In the next image you see that the tree nodes of the 'Fishes' folder reveal the name and the date of the version and visualize the alternate view mode by means of a background color.
Restoring an older version of a folder
In the 'V1' view mode you can popup the 'Fishes' folder's menu and select 'Restore instance'. On the 'Restore instance' window that opens you click 'Start' to initiate the restore process.
Confirming the restore process
After confirmation, the restore process will scan the entire folder to examine and process the underlying objects.
Restore process performed
At the end of this process the folder is automatically switched back to view mode 'Latest'. Close the 'Restore instance' window to take a look at the result.
The older version of a folder completely restored
The versioning notes topic nor 'The tuna' subfolder is available anymore and this is how the folder was in the 'V1' version. Also the images and files contained in the topics are automatically included in the restore process.
If you restore an older version then the objects are always restored in their ‘Work’ state (you see red rectangles all over the 'Fishes' content). This allows you to check or to work on the restored data. If everything is all right you need to publish the restored objects to reactivate them.
Here in this example we have restored the entire 'Fishes' folder. As mentioned in the beginning of this topic, the restore removes all ongoing work in the 'Fishes' folder. You can also restore older versions of individual chapters and topics without destroying work in progress on other objects in the folder. This working principle is explained in restoring individual objects and considering work in progress.
You can also recover older versions of objects you have removed. This approach is explained in recovering removed objects to their original location and recovering removed objects to a chosen location.
