NOTE: Outlook likes to remove "extra" line breaks sometimes.....which is
really bad for scripting. Be sure you check to see if it says "Extra line
breaks in this message were removed", and if it does, click on the message and
"Restore line breaks". Otherwise, the Storage Node name write to file section
is mangled. Thanks.

Subject: [Networker] Simple UNIX Clone script - for use by community
For those of you looking for a way to clone a subset of your data, or
clone on multiple storage nodes/libraries, we have recently crafted a nice,
clean, simple multi-node script that can be setup on your master server in a
cron (we have it run at :40 of each hour) and will clone, per SSID, whatever
pool you define for clone. In our case, we only have a subset of data getting
cloned.....the 'critical' environments. To segregate the critical data, we
push to a critical-only pool, "BR Pool," and only clone that pool. All
non-clones go to "One Month" and are not impacted by the script. Obviously,
changes in the mminfo line of the script could result in different SSIDs being
generated (i.e. not just FULL BR Pool savesets from within the last week only
having a single copy).
Looking for feedback on the script, things we haven't noticed that
might be gotchas...people who'd think this would work for them....etc. But
after many many (MANY) iterations of various and sundry clone scripts, most
MUCH more complex for what is now no apparent reason, we are happy with how
simply and elegantly this seems to get the job done and we thought we'd share.
Thanks in advance for your time and attention.
