Hi,

instead of yanking users out of /home/blast, I think it might be more
helpful to create an area in the scratch discs that is backed up. don't
need to be all that often, maybe once a month or even once a quater.

I remember it happened to both Adrian and Aaron when considerable portion
of their work were lost due to scratch disc failure. If the scratches on
bud10 fail right now, I estimate about a month set back on my work. All
the ntuples must be refiltered, all the monte carlos must be regenerated,
plots remade, latest changes to codes must be recalled and reprogrammed
from the last point saved in CVS.

I believe this is partly the reason why people are reluctant to use the
scratches but instead put significant amount in home/blast.

also with time, a lot of temporary files could be left on one's home dir.
they do not show with "ls" command, for example:
         .autosave-*
         .save*
         .backup-*
         .nfs*
they should be cleaned up regularly.

Thanks.

Chi
