Dears All, I have used rsync on Cygwin for a long time to backup data on my WinXP laptop to a NAS server. Several days ago I had a problem with my user account on the Laptop and I needed to create a new account and delete the old one. Fortunately my data were on a separate partition (fat32) so I did not lose anything. Now when I try to use rsync again on the same data I always get the following error. I have the NAS mounted as a network resource, I am able to browse all files on the NAS both with Explorer and inside the Cygwin shell and I use the following command in the Cygwin shell: $ rsync --delete -avz pubpapers //nas/Winmarra/pcbackup/. The process starts correctly then after a while it hangs with the following output: building file list ... done deleting pubpapers/incoming/paper1.pdf deleting pubpapers/incoming/paper2.pdf ... (a long list) ... pubpapers/ pubpapers/flame.bak pubpapers/flame.bib rsync: writefd_unbuffered failed to write 10609 bytes: phase "unknown" [sender]: Software caused connection abort (113) rsync: write failed on "/nas/Winmarra/pcbackup/./pubpapers/flame.bak": No such host or network path (136) rsync error: error in file IO (code 11) at /home/lapo/packaging/tmp/rsync-2.6.6/receiver.c(291) rsync: connection unexpectedly closed (158102 bytes received so far) [generator] rsync error: error in rsync protocol data stream (code 12) at /home/lapo/packaging/tmp/rsync-2.6.6/io.c(434) rsync: connection unexpectedly closed (58 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at /home/lapo/packaging/tmp/rsync-2.6.6/io.c(434) After the error I am still connected to the NAS and I am still able to list all the files there, so the connection is not broken. I only notice that in the error message the path is written with a single slash ("/nas/Winmarra/etc...") instead that "//nas/Winmarra/etc..." but maybe this is only a rsync internal message. Can you help me please ? Regards, Franco
