All Vibe users can restore individual entries and attached files if the entry has been deleted but not yet purged. For information on how to do this, see Restoring Deleted Items
in the Novell Vibe 3.2 Advanced User Guide.
If an entry has been deleted and also purged from the Vibe site, it can usually be recovered from the archive store by a Vibe administrator, but this is not an easy process. Contact Novell Support for assistance.
