# 同步设置

依次打开菜单 Edit >> Preferences >> Sync

同步选项，本地数据库和 EndNote online 数据库同步。[科研动力](http://www.howsci.com)认为这个功能稍稍有点蛋疼，因为授权有时间限制，还不如[EndNote Library 建立技巧](http://www.howsci.com/endnote-creat-library.html)中利用网盘同步

### Enable Sync

这个是同步的总开关。如果购买了 EndNote 授权，有**两年**的免费同步时间。如果已有账号，输入账号和密码即可，如果没有账号和密码，需要注册一个

**注：**同步前建议备份数据库，推荐[压缩备份](https://app.gitbook.com/s/-LrgCHEEK5wsSALfCziF/04Library/Saving_a_CmprssdCpy_ofa_Lib.htm)

参阅[EndNote 的同步功能 Sync](http://www.howsci.com/endnote-sync.html)或[数据库窗口](https://app.gitbook.com/s/-LrgCHEEK5wsSALfCziF/04Library/About_the_library_window.htm)了解如何同步

### Sync this EndNote Library

此处是设置同步的哪个数据库。此处不能设置，是在 EndNote 窗口同步后自动出现。第一次是空白的，当同步一个数据库后会自动填充

### Sync Automatically

是否自动同步，选中 EndNote 会在后台每15分钟同步一次
