Netbackup can't backup ~$arquive.docx - Office temp files

Hi all!

I'm running Netbackup 7.5.0.7 and I'm receiving this error:

Warning bpbrm(pid=6384) from client brspobkp02: WRN - can't open file: <Local>\~$<file>.xlsx (WIN32 32: The process cannot access the file because it is being used by another process. )

This error started 1 month ago, at the beginning was 1 or 2 files, but now it's increasing, now I receive more than 20 erros... all from office temp files.
