Backup & Sync
From here, you can export and save a full backup of your whole song library formatted as a .SBPBackup file. This includes all songs and setlists, but does not include the values of any settings you may have set.
Use the restore option here to restore any backup you have created.
Note: If the you try to import a backup containing a song that is already in your song library, a new song will not be created but instead your existing song will be used. For two songs to be classed as identical, they have to have the same title and body (Chords and lyrics).
You can sync your SongbookPro library to the cloud to synchronise your library between multiple devices running SongbookPro or just use it as an easy way to backup your library. For detailed instructions on using the online sync feature, please see the article here.
