[OpenIndiana-discuss] funky beginer questions

Running 151a8

Now I've got oi running and becoming slightly familiar with zpool and
zfs cmds, I need some coaching as to how to employ the zfs fs.

My general aim is to backup other computers but also want to have a
few zfs fs that serve a windows 7 box and holds lots of pictures and
other graphic files while work is done on them from the windows box.

The setup I now have is all dispensable and is a practice run.  I've
got the smb server working and shares are available to the win7
machine.

What I need is advice about the actual construction of the file
systems. 

Example: I have an fs p2/rmh  mounted at root /rmh  rmh stands for
remote hosts.

So I have p2/rmh/host1 p2/rmh/host2 and etc.  So what is the best way
to go... should I have the .zfs directory at each level? At /rmh
at /rmh/host1 and at /rmh/host2  maybe even p2/rmh/host2/someproj,
with its own .zfs?

Or better to stop at p2/rmh and let all the hosts be included in the
same snapshots?

How fine grained is really most useful?

One would have to have some mnths of experience to know that answer so
asking for some input from experienced folks.

So that we all know the scene:  I'm doing nothing but homeboy
tinkering, nothing commercial, nothing dreadfully important if lost.

But of course would hate to loose my photo collection or even see any
damage come to it.  So preventing that happenstance and storage for
other home computers are my overriding goals.  How fine grained is
smart?

I realize it all really depends on what I'm after but in fact I don't
know enough to really know that, beyond the stated goals above.  

Detailed experience showing why very fine grain saved the day or
conversely, evidence that fine grain is a pita and better to have one
snap for lots of diverse data... that kind of input would be very
welcome.
