Yes, seems like the best approach, the SDO and DAS components may not 
need to be mirrored as they've not been very active recently.

Makes sense. There's quite a few branches and tags though, so if you 
want to save some space on your server we may not need all of the old 
ones which are just sitting there with no activity.

Just saw it. I had not realized it was there until today :) Thanks!

The example mirror looks good to me except for the fact that the history 
is incomplete (stops when our tree moved from incubator to a top level 
project in June 2008, and some history in mid-2006 to 2008 period is 
missing too).

And again, we probably don't need all the old branches and tags.

OK.

Due to the way git stores things the extra tags and branches won't
really take that much extra space, they just cause the initial
mirroring to last a long time.

It's actually not yet ready, what you're seeing is a partial mirror
that I had to restart after some random network failure. The full
mirror is still being built... I don't have any easy way to predict
when it'll be ready, but I wouldn't be surprised if it still lasted a
few days more.

Once the mirror is done, keeping it up to date is very easy and efficient.

That's most likely due to the fact that only the partially completed
mirror is currently visible. I'll ping you as soon as the full mirror
is done.

Mirroring the branches takes quite a while, but it's easier to get
them all than to select just a few. And once the initial loading is
done, keeping the mirror and all the branches and tags in it up to
date is quite efficient.
