[OSM-dev] Planet diff's revisited

[spaetz]

Hi all, I was looking at the planet generation and archiving proces. Currently we archive them both as bz2 and as 7z files. Download stats tell that in 8 days the bz2 has been retrieved nearly 15000 times while the 7z was retrieved about 500 times. Should we continue to bother with 7z, given that disk space on the dev server is not unlimited?

Also I would like to raise the question of planet diff's again. Would people appreciate 4-weekly full dumps and planet diff's in between? As most of the thing remains the same, we could save quite a bit of disk space with that, I guess.
The catch is IMHO, that the files are too big to be handled with std diff tools, so we (you) would have to use one that can cope with those files (somebody posted them previously, I forgot who).

What do people think?
