It sounds like a blocking issue. Researching about it, I read something
about what you mention here [1]. As it says, it seems that this is
resolved in new versions of Cygwin, although you say that a week ago you
had this problem (with the latest published version?). But this article
is "a bit" old.

He also mentions a problem to doing backup over open files. Have you
experienced that problem?

It does not sound very encouraging. An alternative that I thought as a
last resort was to mount the remote filesystem on the backup server
using Samba and then to use rsync on the mount point, although I'm not
sure how efficient it can be.


Thanks for your reply.

Kind regards,
Daniel
