Storage area properties (Configuration tab)
You can view and modify the following properties on the Configuration tab property sheet for a storage area.
- Online
- A flag that indicates the online status of the storage area. If the check box is selected, the storage area is online. You cannot save or modify
content if the storage area is offline.
- Allows new content
- A flag that indicates whether users can add new content to the storage area. If the check box is selected, users can add new content.
- Allows delete
- A flag that indicates whether users can delete documents that have content in the storage area. If the check box is selected, these documents can be deleted. If the value of this property is false, the storage area acts as a permanent archive.
- Suppress Duplicate Content Elements
- A flag that indicates whether Content Engine is to add only unique content to a storage area. If the check box is selected, Content Engine adds only unique content. Specifically, if incoming content duplicates existing content in the storage area, the incoming content is not added. By default, Content Engine does not check for duplicate content. Consider selecting this option for those storage areas with high-volume content ingestion, such as when archiving e-mail messages to a Content Engine object store.
- Content caching
- The level of content caching that Content Engine permits for the storage area. This level is set independently of the server hierarchy owner assignment for content caches that indirectly determines the storage areas serviced by a cache. (For specific information about assigning cache areas to server hierarchy owners, see Assign a content cache area. For general information about content cache areas, see Content cache areas.) Click the appropriate radio button to select one of the following caching levels:
- Not Allowed
This level does not permit caching of storage area content.
- Cross-site Only
This level permits caching of storage area content only when the storage area does not belong to the same site as the server accessing the content. In the typical case, this level permits a storage area to be serviced only by cache areas not in the same site as the storage area. (The typical case is when both the server and the cache area used by the server belong to the same site.)
- Allowed
This level permits caching of storage area content to any cache area.
- Delete method
- The method that Content Engine uses when deleting document content from the storage area. Click the appropriate radio button to select one of the following deletion methods:
- Non-recoverable
This method renames the content file before deletion, which makes the deleted file unretrievable by its original file name. The content of the deleted file, however, might be recoverable by a file system utility such as Norton Utilities. (The content is recoverable to the extent that other files have not overwritten the disk space occupied by the deleted file.)
- Destructive
Overwrites document content with zeros before deletion. Provides the deletion level recommended for clearing and sanitizing media that is less than top-secret.
- Purge
Overwrites file content three times before deleting the document. Provides the highest level of deletion recommended for purging top-secret documents.
