I use this script to stage all savesets from the AFTD to tapes and it runs
according to what I set it in the cron.
/usr/sbin/mminfo -avot -q 'volume=U00001,copies<3' -r "ssid" >
/nsr/logs/unixssid.stage
/usr/sbin/nsrstage -b 'Unix Clone' -m -S -f /nsr/logs/unixssid.stage

Michael,
We've always used automatic cloning without a problem*. I like it
because it immediately verifies the readability of the original backup.
If your "monthly fulls" are in their own group is will be easy to turn
cloning on for them. We automatically clone every backup and send the
clone tapes off-site (some one other than Iron Mountain) every working
day.
If you are going to manually clone I would think cloning by Save Set is
the way to go since there may be other save sets on a volume rather than
the ones you are interested in. In the GUI (7.2.2 but there must be
something similar in later versions) under Save Set Clone you can query
save sets by date, pool, client, maximum level, etc. so getting the list
of save sets shouldn't be a problem. Set your dates appropriately and a
maximum level of "full" (level 0)and you should have a list of save
sets. I believe there's an "mminfo" query behind the Save Set Clone
that produces the information but I'm not familiar enough the mminfo
command to write it off the top of my head and can't take the time right
now to research it.
Dave
*Of course there is the occasional problem with a bad tape or bad drive
etc but nothing directly attributable to cloning rather than backups to
tapes in general.

Subject: [Networker] Cloning Backups
I am sure this has been discussed in the past, but after going through
the documentation on this subject I must be confused. I am currently
running NW version 6.1 build 186 on a solaris box running sun os 8.
Everything works well for the most part, but now as part of a DR plan, I
am being asked to create a clone or copies of my monthly fulls to be
removed from the library and moved offsite using IronMountain. Nice
idea, and shouldn't be too difficult to do, I thought. Looked through
the gui and realized that there were basically two methods: cloning
volumes and cloning sessions. After going through the manuals and
looking for suggested approaches, I went ahead and set up a clone pool
and slapped some tapes in for my first clone process. I was interested
in cloning my last full backup, and without knowing just how to
determine how to figure out what all was needed, found the 5 tapes that
were used for the last full backup and selected those 'volumes' for
cloning volumes. However, I am now on tape number 6 from the clone pool
to backup the 5 tapes that I believed were used/required/comprised the
last full backup. So I have a few questions if you wouldn't mind:
1) what is the best mechanism to determine just what was used for the
last full backup
2) what is the suggested approach for offsite storage of cloned backups
3) any other questions I haven't asked?
Any additional information and details would be MOST appreciated.
Thank you in advance
Michael Weiner
