Suggestion: Debdelta for your servers to reduce bandwidth !

Postby dbkblk on Thu Feb 23, 2012 2:25 pm

Hello Mint Developpers !

I'm used to use debdelta to make dist-upgrade on my debian desktop, to reduce the bandwidth usage when upgrading. Debdelta recreate the packages locally and only download the differences. If you could configure it on yours servers to generates the differences in packages between to update pack, i think you could dramatically reduce your bandwidth !
Of course, some work will be needed to integrate it to your update manager.
http://debdelta.debian.net/

The only difference, client sided, is to do "apt-get update && debdelta-upgrade (to recreate the package) && apt-get dist-upgrade (which will download only the package that aren't recreated.

I hope it help !

I think debdelta is a great tool but I'm not sure using it with the Incoming Repositories is of much help.
I appreciate the code that you post, however, since I do often use a script to clean and update a released version.
Even with fair to decent bandwidth it helps to keep the traffic down (certainly a good thing) if more people use debdelta.
