The Message Broker Toolkit workspace contains your personal settings and data, such as message flow and message set resources.
You can have multiple workspaces in different locations and you can also have references to projects that are in other locations, therefore consider all of these locations when you back up your resources.
The workspace directory contains a directory called .metadata, which contains your personal settings and preferences for the Message Broker Toolkit. If the .metadata directory gets corrupted, you lose these settings and the Message Broker Toolkit reverts to the default layout and preferences; if you have not backed up the .metadata directory, you must manually set any preferences again and import any projects, such as message flow projects, that were displayed in the Broker Development view. To back up the .metadata directory, just take a copy of the directory.
In the workspace, a directory exists for each project (message flow project, message set project, or server project) that you have created in the Message Broker Toolkit. These directories contain your data, which must be backed up.
Use one of the following methods to back up the data in your workspace:
To restore the resources, copy the directories back into your workspace directory and import the projects. For instructions, see Importing in the Eclipse Workbench User Guide.
