Hi, I map a folder, for example /tmp, to Samba share folder by using "mount -t smbfs -o username=...,password=... //sambaserver/sharename /tmp" then rsync another folder with samba folder by executing "rsync -uvr --progress /Apps/ /tmp". /Apps is just example. If the file under /Apps has trailing dot in its name, for example "abc.", the destination file name will be "abc". But the trailing dot is preserved if I do rsync between two local folders. So that Wayne Davison (wayned@users.sourceforge.net) answered to my last post that the problem seem to be the destination file system. But I can keep the trailing dot if I use cp command like this: "cp -Rf /Apps/ /tmp" So, the cause is neither only samba file system nor only rsync. The option -u has no effect in this case, because "abc." in source folder and "abc" in destination folder is different. Whenever I run above command, rsync copy the whole file again and again. I am using: Redhat6.2 kernel 2.2.16-4, samba-2.0.7-4, rsyn-2.4.6-3 Thanks for any helps Tran Hong Quang
