You can make a backup to external venti with a
single easy venti/copy -f.

That question was twisting my mind, too, when I set it up. ;-)

plan9.ini(8) and boot(8) answer the question. If the venti
environment/plan9.ini variable is set to a local venti device
venti gets started previously to fossil.

(Therefore, its configuration must be written to the device with
venti/conf)

A fossil that made an archival snapshot to a venti depends on that
venti. Consider the venti as the main storage for the fossil, not just
as backup.

(At least thats my experience with venti & fossil; and what the venti
paper says. Correct me if I'm wrong)

So, for archival snapshots, the venti should reside on the laptop.
(but it may be copied to an external venti now and then, of course)

it does it when you next switch it on.

yes, you might miss a date or two, but then again,
nothing happened on the missing dates anyway.

My question was, how do you ensure that at archival time the laptop
is running? I'm talking about the automatic snap -a.
And, how to start venti before fossil on boot?

I'm too simple right now for that :-)

I have a venti and fossil. snaptimes are something like 15 and 1440 or 
some such. 

So I have a perpetual history of all my files on my laptop. HEAVENLY.

I mean, do you just keep your laptop running all the time
or do you force a snapshot at a convenient point. Forcing
a snapshot is an explicit action of backing up and can as
well be performed on an external venti?

not to mention archive and snapshot.

i'd find it difficult to survive without these...

you can replicate it (eg, for backup).
you can reinitialise fossil from a venti archive.
you can use the venti contents without fossil.

What's the point of venti on a laptop anyway?

Thanks Russ.

Ummm, so I have too many list of TODO.
I have to forget some of them to maitain myself alive!

Now, I have 'still picture' of TV programs in Japan☺, Fusion 878A 
and original 878 is a different chip, which I had to know it before.   
It's difficult to get original 878 chipped TVtuner here now...

not in the forseeable future.

30GB should be enough for xp and plan9 on a laptop.
on that disk i'd give fossil 4GB for other, 1GB for main,
and venti 5GB.  that's more than plenty for a laptop
in my experience.

[9fans] IBM T42

[Kenji Okamoto]

Is there anyone using IBM T42 notebook?

I got it for WinXP for my duty work, and it'll be used only
for Powerpoint.☺   However, if it's easy to run Plan 9 on it, I may
try it.

So, the expected problems:

(1) WaveLan Ok?
(2) Radeon Ok?

By the way, its disk space is only 30GB, and I think its not enough
to use it both for WinXP and Plan 9 fossil+venti.   How are the people
running Plan 9 and Windows on such a notebook machine?
Replaced HDD?  or just use both on the 30GB HDD?

Thanks in advance.

PS.  --->Russ.  Do you have a plan to impleremt overlay mode
