We rely on the system's wake and scheduling features to do their things. If those don't work reliably, it's hard for us to work reliably, and harder still to "work around" the problem, since we didn't "write" that part.

As far as logs go, there's no plan for an integrated log "folder", no. But we're always looking for ways to improve things, and I have various ideas in this area.

But, anyway. If the drive wasn't mounted, your backup would fail. Why the second one failed is something I can't explain, but if SD! wasn't "waiting to run" when you woke, it means it probably didn't wake at all, or went to sleep very, very quickly after waking.

If you're comfortable doing so, you can try to change your crontab to run the event at 3:30:30 by changing the "0" at the start of the line to a "30". Then, set your wake event to 3:30, and see if that works...
