    Hi pokiri-6646,

    Could you please share us the result of “Select @@version” and the query you used to make compressed Differential and Transaction Log backups?
    Please use the following query to check if the backup file is compressed:

    RESTORE LABELONLY FROM DISK = ‘physical_backup_device_name’  

    IsCompressed =1 means the backup is compressed.

    Best Regards,
