I set up a crontab for backing up my music folder and some files are
failing with the error:

rsync: recv_generator: failed to stat "/media/Vault/mint_music/VA-
Cosmic_Gate-Back_2_Back_3-2CD-2007-POW/CD2/(04) [Genix - Phused
(Marcus Sch\#366ssow Remix)] Track04.mp3": Invalid or incomplete
multibyte or wide character (84)

Why is this and is there a way to force it to work anyways? I mean
the files are working fine on my home folder HD... but.. they wont be
copied to this drive.

home folder drive is EXT3, backup drive is NTFS.
