On one of my 7.2.2 build 494 Networker servers,
I've got 1,700+ savesets devided into 2 tape pools across 4 x 1 TB AFTDs.
I break them down to some small batches, 100 savesets per run per LTO2 tape
drive over 4 drives.
It is much more manageable this way.

I clone absolutely everything by ssid under some of my 7.2.2.494
systems. I've bigger lists than that in by file and by stdin without any
issues. Just looking at recent tempfiles I have lying around - one has
528 ssid's in it and adds up to 11435 bytes, and that went through just
fine. Not to say there's not a bug in 7.3.3 though. I will be doing
a big batch on a 7.3.3 system this afternoon and will keep Ian's
reported problem in mind for that.

I don't know if this applies but often there is a limit on the length of
a command line. In Solaris I believe it is 2048 bytes. So even though
you're putting the savesets to be cloned in a file it may be parsing it
into a command line as if you had tried to write it all without the
savesets file. So it's not so much the number of savesets you can clone
but the total length of the command line that results. For instance if
your savesets were name a, b, c, etc. you might be able to clone well
over 1000 savesets.

I'm in the process of binary chopping to find the limit, but it
appears that there is a limit to the number of savesets I can
reference in an nsrclone -S -f /file/name (Networker 7.3.3 on Solaris
10). 175 is OK, while 250 is too many.
I have a script which implements a policy of writing a daily tape of
activity in a given pool, but not deleting the files until a week has
passed. Recently we wrote a lot of savesets during one day, taking
the amount of activity to go to tape at night over the magic
threshold, from which there is no return. nsrwatch shows the clone
job start (cloning session: XXX save sets reading from...) but then
immediately reports completion, while the client sees the messages
below.
