Database cannot be incrementally backed up because a full backup has not yet been done.
An incremental backup extracts only the data changed since the previous backup.
Do a full backup before doing incremental backups.
For a history of database backup activity, view the Database Backup Status view under Public Views\Exchange 2000.
