           Summary: Rsync re-copies up-to-date files on external FAT drive
                    after reconnect
           Product: rsync
           Version: 2.6.9
          Platform: x86
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org

Hi,

I'm using rsync 2.6.9 in Cygwin to keep files on a NFS partition in sync
with
files on a FAT32 partition (external hard drive). The problem is that after
reconnecting the HD to the computer, rsync won't identify the files on the
FAT32 partition as up-to-date on the first try. Thus it will copy all files to
the external drive again (although they're already up to date). Only after
complete re-copy/rsync of the files the program will work as intended for the
following executions of rsync. But after a reconnect of the HD it all happens
over again.
The command line is

$ rsync -rtW --modify-window=1 --delete /cygdrive/d/source /cygdrive/g/dest

Any solution in sight? Thanks in advance!

Regards, Nils.

Please reconnect the HD and then run rsync with the -i option to find out why
it thinks the files need to be transferred.

Darn, can't reproduce it at the moment. Appears only from time to time.
Sorry
for the inconvenience.

This may have been a time-change glitch.  E.g., FAT stores times in localtime
with no DST offset, so when DST changes, all times on a FAT filesystem appear
to shift by an hour.
