You as the Novell Vibe administrator can enable two kinds of data quotas:
User data quotas
Workspace and folder data quotas
You can enable one of these quotas, or both of them.
User data quotas limit the amount of data individual users can add to the Vibe site. Any files and attachments that a user adds to the Vibe site counts toward his or her data quota, regardless of the folders or workspaces where the user adds them.
Workspace and folder quotas limit the amount of data that can be stored in individual workspaces and folders.
Sub-workspaces and sub-folders that have a data quota are subject to their own data quota as well as any data quotas that exist on parent folders and workspaces. For example, consider a workspace that has a data quota of 50 MB. The workspace contains two sub-workspaces: Workspace A and Workspace B. Users cannot upload data that is in excess of 50 MB into either of these sub-workspaces. Furthermore, users cannot upload data into both of these sub-workspaces that is in excess of 50 MB (for example, users cannot upload data that is in excess of 30 MB into both sub-workspace, because the amount of combined data for both sub-workspaces is greater than 50 MB).
