Another cygwin/rsync question

[Henri Shustak]

> I'ts a simplistic backup using rsync from a Windows 2k3 machine to a Linux box out on the 'net, using pre-shared ssh keys. In this case I'm saving, files belonging to various users, using the administrator account on the windows machine and the destination is a normal user account and its home file area. I'm using the rsync --chown option to stop rsync trying to change the ownership/mode on the destination filesystem. I'm not bothered about saving the file perms/ownership.

If I run rsync running on a larger batch of files it seems to stall. Using the -vvv option I can see rsync, on the windows.cygwin end, collecting a list of files prefixed by

Ken, I am not sure I am able to help you with this problem. However, it sounds like you have quite a lot of experience with rsync and cygwin. The LBackup project <http://www.lbackup.org> currently has no one maintaing cygwin compatibility. If you have a look at the LBackup project and are interested in helping out then just let me know. Your assistance would certainly be welcomed.

That said, I have a couple of suggestions :

 (1) Are there any files or directors being backed up which 
     have non-asci characters in the names? Also, have you
     tired removing the parts of the path with spaces or
     tired the rsync on a directory which has no spaces?

 (2) If you use a password rather than public key for
     authentication will it work?

 (3) If you bypass SSH and setup an rsync server on the backup
     source will it work.

Beyond that I am not sure. Hopefully someone else on the list will be able to assist you with some better suggestions.
