[PLUG] question on rsync behavior on NTFS

[website reader]

Does anyone know why rsync command echoes the folders when backing up
from an ext4 folder into a NTFS folder?  Normally, using the "rsync
-avg --delete /folder ." command on a linux file system (ext2 or ext3
or ext4) rsync will only indicate a true update to the files/folders
if it occurs.

However for a reason unknown to me, rsync seems to post all folders
when backing to an NTFS file system regardless if a true file update
occurs or not.

Does anyone know why this is happening?
