Using new FULLIFREQUIRED option with SQL 2005
"Note that this option is not available if SQL Server does not return SQL error 3035 or 4214 when a full backup is required. This is the case when performing transaction log backups on most SQL Server 2000 or 2005 service packs, and when performing differential backups on most SQL Server 2005 service packs. When using this option on SQL Server 2000 or 2005, warning 483 is returned to alert you that a full backup may not have been taken."
So this seems to imply that with some service packs of 2005 this may work. Is this documentation in error? Or are the some conditions were I could use this option for SQL Server 2005? Please clarify what builds of SQL Server 2005 will allow this option.
