Ah but this is really not true. Volume shadow copy makes snapshots of files and through that it can make a backup of an entire NTFS including files with a lock on them and fully quiesced. It was invented for that exact purpose. Backup software on windows leverages this functionality well. It took much longer for Linux to have something similar.
I have many criticisms of NTFS like it being really bad at handling large volumes of small files. But this is something it can do well.
The lock prevents other people from copying the file or opening it even in read only, yes. But backup software can back it up just fine.
