You can do manual backups by tapping Options in the library and then tapping Backup All. Please make sure the backup file is transferred to your computer for safety. If you use Backup All to iTunes, you can import backup in Import > iTunes > Backup xxxx-xx-xx.zip.
How to save a backup file in my computer using iTunes, and restore it later?
If you use cloud storage such as Dropbox, GoodNotes can upload your documents automatically to the cloud storage. It can be enabled from Options > Settings > Automatic Backup.
if a file failed to upload, GoodNotes does not attempt to re-upload in the current version. Large files may take too much time to upload than the allowed time for apps to remain in background and become missing as a result. We plan to fix it in future versions.
