Just to give you an idea
The correct formulating of the query and the report is essential
then I filter all platforms that are not servers and bild a list of ssid
any ssid of a continuation saveset is ignored (we have still a few
version 5 clients)
and any ssid with a pssid of nonzero (basically another way to test if
it is a continuation saveset is also dropped .
this list is then processed for cloning if the -w option is given.
the 2 modules for file locking are not included in the attachment
they are not essential for understanding the clone script
if you need them holler.

It is crucial to know when it is appropriate to withdraw our attention
from things that disturb our
mind. However, if the only way we know how to deal with certain objects
is to avoid them, there will
be a severe limit as to how far our spiritual practice can take us.
