Windows Backup from Server to QNAP

I have a shared folder "Backup" on QNAP

you can't transfer files to QNAP using windows backup unless change smb.conf

Windows Server Backup failed with error "The version does not support this version of the file format"

you must add "strict allocate = yes" in section of your backup folder
