Well, the standby has to be a replica. So there would be occasion, say
on a machine crash or something, when the standby reboots, or it is
installed much later than the Primary. So when it is booted, I have to
make sure it is an exact replica of the Primary.

will work on that for sure..

Now, the server as such, and the copying mechanism itself has been sort
of cleaned up, and possible error points in the copying of files are
being logged. Now things seem a lot brighter!!
