This gem will download your tweets from Twitter and save them to sqlite3 database and plaintext (yaml) archive file.
$ gem install twitter_backup
First of all, you need to create an app at https://dev.twitter.com/apps Your app will be assigned a 'consumer key'/'consumer secret' pair and you as a user will be assigned an 'access token'/'acces token secret' OAuth pair for that application. Without these credentials you won't be able to use TwitterBackup.
Now, all you have to do is to run
$ twitter_backup
If you want to know, what's happening during your backup process, use verbose mode with -v.
$ twitter_backup -h
-v, --verbose Enable verbose mode
-f, --force Try to download tweets, even if it seems useless
-s, --seed Try to download tweets older than the oldest one you have
-c, --config Config file. Default: ~/.config/twitter_backup/config.yml
-h, --help Display this help message.
