It is for backup actualy, but only non-incremental backups. I was hoping that 
this basic problem has been seen and there was an easy answer!. So a script 
it is, my way of dividing up the files is just to start recursing through the 
directory structure totaling up the file size. when some limit is reached 
call that an iso. I am sure if you allow some percentage for padding, with a 
bit of fiddling this will work ok.

I think the time has come for a look at my backup stratagy, as i believe it is 
poor (mostly due to lack of time at work to devote to these things) and the 
cartoon strip in LXF this month sums it all up :-)

Currently my fallback system works as follows

Primary server RAID 0 on two disks

Secondary server rsync to primay server every night
Isos are created of the (secondary servers version of) /home/* file system (3 
in fact) and these are burnt to DVD from _time_ to _time_ (yes appaling I 
know). Also the ISO's are also copied to other ofsite PC's like my home one 
etc from time to time, where time to time is a random integer that is 
probably too big.

I was thinking that a weekly burn to DVD would be a big step forward and I was 
going to do a complete burn once a week, semi automated (hence the need for a 
iso creating script). 

Any ideas, comments, stiff talking tos, flames etc?
