Online Backup didn't save my quicktime movie files

my canon camera saves qucktime movies with file names like this MVI_0362  and after searching my saved online files for ones with MVI in the name or with a .mov extension I came up with no saved files and I'm sure I had these types of files on my PC that was backed up. My phone saves files with a .mp4 extension and these files were saved via online back up. Any Ideas?
