The following statement
BACKUP LOG [AMS_Prod_log] WITH TRUNCATE_ONLY
works fine in SQL Server 2005 but it doesn’t with 2008. It seems truncate_only is deprecated in 2008. Could you please let me know how to achieve this in 2008? What care needs to be taken like backup… etc?
This is the list of features depreciated in SQL 2005 i.e. they will not be available in SQL 2008.
