I have added three PPAs. How do I backup their configuration?
Where is the PPA config file?

PPAs tend to be added into their own files in
/etc/apt/sources.list.d/. Here is an extract from a
ls in that directory on this system:
am-monkeyd-nautilus-elementary-ppa-maverick.list am-monkeyd-nautilus-elementary-ppa-maverick.list.save awn-testing-ppa-maverick.list awn-testing-ppa-maverick.list.save banshee-team-banshee-unstable-maverick.list banshee-team-banshee-unstable-maverick.list.save banshee-team-ppa-maverick.list
If you're trying to move these to another system or back them up, just using these files is not the best idea because these files have version specific strings in them. Look at my answer on another question. It will generate a list of PPA strings that you can add back manually (or with a little script that just loops the list).
