Using rsync to download photos from camera

[T o n g <mlist4suntong@yahoo.com>]

Hi, 

I've been using rsync for many years to synchronize between local
directories or remote PCs. I've also successfully used rsync to synchronize
photos from my Pentax Optio camera to PC, so that only the newly shot photos
are copied.

However, I found the very same approach doesn't work for the Canon camera:

  $ rsync -nvua /mnt/camera/dcim/*/* . 
  building file list ... done
  [...]
  img_0135.jpg
  [...]

  $ stat /mnt/camera/dcim/100canon/img_0135.jpg img_0135.jpg
    File: `/mnt/camera/dcim/100canon/img_0135.jpg'
    Size: 892127          Blocks: 1792       IO Block: 32768  regular file
  Device: 811h/2065d      Inode: 9817        Links: 1

    File: `img_0135.jpg'
    Size: 885981          Blocks: 1737       IO Block: 131072 regular file
  Device: 80eh/2062d      Inode: 166857      Links: 1

I.e., rsync insists to copy again files that have already been copied,
although I see no obvious reason why it is doing so.

Please comment. 

Thanks a lot
