Several months ago I set up an OpenSUSE box to act as a remote
backup server to a Windows 2008 Server, running rsync over ssh from
the Linux box, with Cygwin on the Windows server. It had been
working well until a couple of weeks ago when I had a problem with
one of the Access databases (.mdb file) the server hosts. Basically,
rsync stopped processing and just hung when processing this file.
Restarting the server did not seem to clear it up. The application
using the databases was also having shutdown issues, so it appeared
to be an application-caused hang. Subsequently, though, I am seeing
other hang-ups. I have spent time this morning trying to diagnose
the problem, which manifested itself with a printer driver (/Windows/
System32/spool/drivers/w32x86/3/PCL5ERES.DLL). Restarting the server
didn't make a difference. I therefore updated Cygwin to ensure I was
on the latest version:
$ cygcheck -V
cygcheck version 1.90.4.1
System Checker for Cygwin

After restarting the server, I ran the backup script. Now it is
hanging on bash.exe, which I assume was updated as part of the
Cygwin update. The backup command in the script is:
rsync -auvz --exclude-from=$EXCLUDED2 --rsh="ssh -i $KEY -l Backup -
p 3390" domain.name:/ $BACKUPDIR2
The variables are of course defined in the script. There are no
errors written to stdout until the script is cancelled - it simply
sits not processing until it is cancelled.
I am remote from both servers and have had no connection
interruptions during my testing.
I'd appreciate any ideas on resolving this.
Sorry to reply to my own post. I tried some other options, and found
that if I used the rsync "W" option instead of the "u" option, the
backup ran cleanly.
Can someone clarify why this change affects the process?
Thanks,
Des
