    TRUNCATE_ONLY option does not reorganize the file but try to free the empty block at the end of the log file...It is possible that without page-reorganization there is no actual space to free... Instead of TRUNCATE_ONLY use tager_size...

    DBCC SHRINKFILE('your-log-file', 200) -- for 200 MB

    It will take much more time as SQL will try to reorganize pages inside the log file and drop them if marked properly by the backup process...

                          how can i check the old recovery model? i try to change it from DB options but after changing to simple LOGS backup is not possible. DB is showing its size 221GB including LDF size.. Any suggestion to get out from this issue.

                                Is your database set up for replication? If so, the replication is broken and you'll need to fix it. If it's not set up for replication, then you'll need to remove the replication settings. Try sp_removedbreplication[^]:

                                EXEC sp_removedbreplication 'YourDatabaseName'
