How to Backup All Tweets from Twitter

I'm not sure it's possible to get ALL tweets without providing a search term. That would be a hell of a lot of data - even just for this year.

There are a list of services here however all them require you to provide a search term.

Your best bet may be Archivist as they actually allow you to download the source code of the site. You may be able to customise this to do what you want.

If all that fails, your only other option would be to contact Twitter directly and see if they can provide you with a years worth of data. I wouldn't hold out much hope for that though!

Good luck!

To see all tweets, from anyone, directed to a certain user, you can simply search for "@username". For example, try https://twitter.com/search?q=%40codinghorror to see all replies to Jeff Atwood.

I think I originally misunderstood the question, here's my original response:

Yeah, person A's Twitter replies to person B (tweets that begin with B's @username) are only visible in the Twitter stream of those followers of A who also follow B. I think this feature is fairly non-obvious, especially for new users.

To my knowledge, the easiest way to see also the "@ replies" (without following the other user) is to go to the user's profile (at the Twitter website: http://twitter.com/username, or through some Twitter client) and see their full tweet list there. However, then you'll of course see "@ replies" to everyone, not just to the individual you were interested in. To put it otherwise: no, there isn't an easier way. To see full "conversations" in your feed, you'll have to follow both (or all) parties taking part.
