I am using BackupPC 4.0 on a debian distro to backup two windows computers running Cygwin.  I am using rsyncd as the vehicle to back them up.  When I try to start a backup, the backup fails apparently because of an rsync_bpc issue.  The log file entries are below:

In one of the log files, it indicates the following: “Running: /usr/local/bin/rsync_bpc” and it has the following error message: “ERROR: failed to read a password from /data/BackupPC/pc/agm-pc/.rsyncdpw5658”. 

 

Does anyone recognize that error and know what it means?  It seems as though it needs some sort of password but I don't know where to input a password.  The only password I know of is in the secrets file on the target Windows machines, but this looks like it is not even connecting to even get that far.  

Thanks in advance.
