Rsync and incremental updates on top of Original CDs

2001-02-17 Thread arifi

Hi,

Hoping that this is not a faq (I could not find an rsync-faq, btw.),
I am looking for the answer to the following question:

Once one has the latest 2.2_rev2 Official CD's (let's say I bought
them), can rsync be used to incrementally update these w/o drastic
network traffic, once 2.2_revX or 2.3 or 3 ... etc become available ?

Well, actually I believe that in releases x.y with (x==2)^(y>2) or
(x>2) too many packages would have changed making this question quite
silly, but I would still appreciate a decisive expert opinion.

Many thanks in advance
-Arifi

it's so simple there are few FAQs :-)

yes - you would have to dd the cd images to your hard disk to work with
(of course)

you will find anywhere from a 30% upto a 60% saving in bandwidth using
rsync for this.  (at least i did for rev0 -> rev2).  of course if you are
using the pseudo image kit 2.X, you will get more like 90% savings if
you have a local full debian mirror available to build the images instead.

i expect rsync savings on packages to get significantly better once
gzip is able to be --rsyncable - but i don't know the timeline on them
getting that accepted and out there.

regards,
