Comment 3 for bug 73452

I am seeing the same on a Ubuntu 9.04 on CIFS mounts using the latest "smbfs" package. Using Microsofts robocopy /MIR as well as ms' file manager preserves timestamps on the server, while rsync and Nautilus doesn't from an Ubuntu 9.04.

Issuing an rsync -a command (trying to maintain file attributes) fails miserably with an error:

rsync: failed to set times on "/mnt/smb100disk2/backup/CR-LD100/.88RC6907010.pdf.p1pkDD": Operation not permitted (1)
...
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1058) [sender=3.0.5]

Is there a solution yet for this problem? Losing file attributes including time information on CIFS shares limits Ubuntu's usability in a professional environment tremendously. We have several TB of data stored on Linux-based CIFS servers and are attempting to move from MS to Ubuntu on a number of clients, but this is so far a showstopper.

Does anybody know of another tool (other than rsync) that supports CIFS correctly on the Ubuntu client?
