Syncing your library backs up your library on the Zotero server, and enables you to use Zotero on more than one computer.
- After you set up a free Zotero.org user account, open the Zotero preferences window and navigate to the Sync tab. Enter your Zotero.org username and password.
- Check the "sync automatically" box, and check both boxes under File Syncing and choose Zotero storage for My Library. This will sync your PDF attachments as well as the citations.
- Zotero will upload your library to their server.
In addition to automatic syncing, you can sync manually at any time by clicking the "Sync with Zotero Server" button on the righ-hand side of the Zotero toolbar.
