[Novalug] Hard Drive Data Recovery

[George Bell]

I don't see much point to making backups of data to the same drive on 
which the backed up data resides, via raid, rsync, or otherwise.  If the 
drive goes, it won't care which data is on which partition and take all 
the partitions down with it.  You'd get some degree of protection 
against human errors like an accidental rm -rf * kind of thing, or some 
rogue application that screws up your file system, but that's about it 
as far as I can see.  If I had such a large disk I'd be tempted to 
either 1) use the rest to store audio clips, video clips of U-tube, etc. 
or 2) install a few more distros to play around with, such as the one
that was presented in the fine talk on Foresight Linux today.
