I panicked a few years ago when I had a drive failure and almost lost my logbooks. What I do now is I do an automatic backup of all my logbooks directories on a nightly basis with Backup Software to a WD Mycloud drive that is hooked up to my home network router. This way if my computer drive fails, the most I could loose is 1 day of log entries.
