 dear crystallographers,
 
 i have an only remotely ccp4 related question :
 
 how does everybody out there do their SYSTEM backups (SGI) ?
 this question is related to a little discussion a few weeks
 ago on LINUX backups. right now i am not doing any. scary 
 ..... so i figure i'll have to buy something.
 
 - CD is out of the question, i guess. i figure i would need
   quite a few CDs to backup our 6 Gbyte hard discs.
   plus some other machine to do the backup on, since on the
   fly burning seems somewhat risky ? CDs work great for our mar
   datasets, though.
 
 - DVD is not quite there yet, as i understand. also, would it be
   synchrotron trip compatible ? prob. not ? would it have to be ?
   i guess CDROM is good enough for that. would DVD hold a full 
   backup ? don't think so (only 4.8 Gbyte).
 
 - leaves us with tape. i thought of some DAT DDS-3 system 
   as as a compromise for now. DDS-4 is a bit spendy still.
   same for exabyte mammoth ( or so ... )
 
 since this is not really ccp4 related i invite everybody to write to my
 personal e-mail adress, and then i'll post a summary, to spare the rest of
 the world from this.
 
 my excuses and 1000 thanks in advance.
 
 
                                   ingo
