Hi,
In addition to what Michael and Aki said. I like to add today's
"home/blast" discussion:
- Increasing the home space would be nice if the associated cost
is not too high. 20 GB is -really- small for 20-30 active users,
which contains 15 (?) PhD theses, for the whole Blast program.
Even some PhD "documents" (including the large figures, etc.),
can take up to GB order-of-magnitude easily, which deserve a
good backup frequently.
- On the other hand; all graduate students and major components
of the Blast projects have a Bud and its large disks (200GB tot),
which is not backed up. I still would use this space, and backup
the crucial data myself periodically (some extra work is the down
side), if increasing the home space becomes not an option. There
are 8 DVD writers, and the DVD media is cheap, and is available
through the common room. I used to do my backup while working on
my thesis.
Regards, and have a happy new year!
Taylan
PS: I had done my job reducing my home usage, as soon as the first
message came about this, and I even gave up some
reproducible-in-the-expense-of-some-extra-work files.
