RE: [BackupPC-users] Backuppc 2.1.0-5 silently hangs backing up o ne particular server using rsync?

[Kris B. <Kri...@sc...>]

To answer my own question, it had something to do with a cygwin-related
symlink on the Win2k host. Running rsyncd on the source machine using:

 C:\PROGRA~1\RSync>rsync --config=c:/progra~1/rsync/rsyncd.conf --daemon
--no-detach -vvv

and then tailing rsyncd.log showed:

Every time it was tried the transfer would always get stuck at the same
point. Looking in that directory on the source with Cygwins 'ls -la' showed:


...
-rw-r--r--    1 Administ None         1678 Jan 28  2003 Dbg.h
-rw-r--r--    1 Administ None         5822 Sep 25  2003 FlexLexer.h
lrwxrwxrwx    1 Administ None           20 Oct 23 16:12 X11 ->
../X11R6/include/X11
lrwxrwxrwx    1 Administ None           20 Oct 23 16:12 X11 ->
../X11R6/include/X11
...

Which is very odd to say the least. Removing 'X11' (on a hunch) produced:

C:\cygwin\usr\include>rm X11
C:\cygwin\usr\include>ls -la | grep ">"
lrwxrwxrwx    1 Administ None           22 Jan 21  2004 X11 ->
/usr/X11R6/include/X11

Stranger still. Removing it again:

C:\cygwin\usr\include>rm X11
C:\cygwin\usr\include>ls -la | grep ">"
C:\cygwin\usr\include>

After which the backup was tried again and all worked just fine. For what
it's worth the Win2k volume in question passed a chkdisk with flying colours
even before the offensive symlink was removed. 

Hope this helps someone in the future...
