This morning I had my first failed cloud backup. I haven't made any changes to my device in weeks.
After I noticed the failure, I updated to Platform Version 2.3.7.140 and still getting same failure.
I have a second C7 with cloud backups on the same firmware and it is not failing. Any ideas where to start looking?
C-7 here with same issue, cloud backups started failing and reported Zwave backup incomplete. I tried the suggestion in the thread below where someone else started reporting this issue a week ago.
Shutdown hub, remove power, wait 45 seconds, power up hub. Run a manual cloud backup which was successful. BTW, this issue is also wrecking some havoc with the Zwave network, at least for me. I had to repeat the power down procedure a couple more times to get my Zwave network to settle down.
I just had this happen today. Last night's backup failed due to Z-wave and the z-wave network was unresponsive. It appears that the hard power cycle fixed it, but this bug may still be out there.
If you haven't already heard from him, can you please PM your hub model and UID to @bcopeland, and let him know that you had the problem w/your nightly hub backup?
If you're on a C7, start at below and confirm that your Z-Wave FW/SDK is up to date on your hub.
If you're on a C8, or if you have a C7 and have already gone through the steps in the topic above (or didn't need to), then PM your hub's UID to @bcopeland and let him know that your nightly backup failed.
