Questions on flar create (flash archive) - burn to several DVDs & make it bootable & ssh across network

Hi,

1)
First, what's the syntax?
"flar create -x "/oracle, /oradata"  -c server1.flar server1c.flar
So is server1.flar the compressed output or it's server1c.flar that's the
compressed output?

2)
how can burn it to DVD?  I plan to ftp in binary mode to a Windows PC &
then do "Copy Data" to burn it to DVD  because after we relocate in a rush
weekend, chances are the network may not be up, so having a local media
(like DVD) to recover the flash archive is a safer bet.  Most of our Sun
servers do not come with a tape drive

3)
is there anyway to span the flar/flash archive output across several DVDs
(& for those servers with 4mm tape drives, span it across a few tapes)

3)
Next, how to I restore them from DVD/tape - boot directly from the DVD/tape
that contains the flash archive or I need to do "ok boot cdrom" too boot up
from a Solaris CDROM first?  If booting up from Solaris CD, what's the  steps/
command to restore from the flash archive tape/DVD


Thanks

1. That syntax looks wrong to me. The -c flag doesn't take an option and the flarcreate command only specifies one flar archive. I don't know what happens if you specify two as you have done. I suspect you would get an error.  So, assuming you only get one archive, then that is the one that is compressed.

2. That should work if you are careful.

3. I don't think there is a supported way to split a flar archive into parts and have them be usable by themselves. You could always split them manually, but you would have to put them back together before using them. One possibility would be to have multiple flar archives, one for getting the system up and running and others for your applications, etc.

4. See http://www.sun.com/blueprints/0404/817-6991.pdf

The "Backup & Recovery" book by Curtis Weston mentioned it's possible to make a
flar (Flash archive) DVD bootable besides holding the archive file but the book says
it's beyond the scope of the book.

Do you know how to make the flash archive DVD bootable?  I have Nero burning software
but only know how to do it for Windows
