Hi,
I noticed that your cygcheck indicates that there are 3 copies of
cygwin1.dll installed (d:\bin,d:\usr\local\bin,c:\winnt) - the one in
c:\winnt is a different version than the other two. You might want
to try reducing those to only one. And, you might want to try a
newer version.
If you've got the disk space, you might try uncompressed tar and
then gzip'ing the resulting archive. Also, you might try redirecting
stdout and stderr to a file on the remote system to reduce the
possibility that a bad connection over ssh might be hanging the
process.
Is it possible that a remote batch job is working in the /data area
at the same time you're trying to do the backup?
Don't know if any of this will help.
Regards,
Doug Wyatt
