Hard device shutdown corrupted data?

[developit]

Last night my phone shut down while I was writing on JournalBook, and this morning all the content appears to be gone. I'm guessing the IDB write failed and corrupted storage. I'm wondering if it might be potentially useful to write a second copy to a second storage medium as a way to prevent that. Thoughts?

Also ability to export backups if that does not exist? If it does that should be advertised more.
