My C-7 quit. No light. Nothing. Got a C-8. No cloud backup. Since I can't access the old C-7, do I have to start over? Or am I missing some miraculous fix?
Might try a different power supply block before abandoning all hope.

And zero local backups saved elsewhere?

I used plugged the old USB cord from the old C-7 into the new power block from the new C-8. No light.
Whenever I updated, I assumed the backups were saved to my PC but I don't know where they are.
When updating hub firmware, there’s an option to create and download a backup but you have to trigger it manually…

Where would it be located or what would the file be called?
HA! This old brain! Looked on the PC and I have a backup from May 2025. Will try to use that.

Are you handy with a soldering iron? Or is there an electronics repair shop close to you? The microUSB connector on C-5 and C-7 hubs was fairly fragile and susceptible to breaking.
With the right tools it is easy to fix - in some cases, even without a soldering iron, it can be possible to bring the hub back to life for long enough to make a migration (cloud) backup.
For an example, take a look at his thread:
Restored! Looks like all the apps are back. Do I need to re-pair the devices? Nothing is talking. Will check the Sonos app.
Yes. Local backups do not have radio data. So none of your z-devices will work.
Before you go down the route of resetting your zigbee and z-wave devices, I encourage you to check the microUSB connector on your C-7. This could well be an easily resolved issue.

Do you mean the USB cord on the C-7? If yes, check it how? Not sure how to check it.
I mean the microUSB connector/port on the C-7. Read the thread I linked to for how to check it.

Be aware though, the local backups DO NOT back up the zigbee or z-wave radios. However, as you re pair zigbee devices they will slot back into where they were.
Depending on how many devices user911 has, it may just be simpler to re-pair the devices. With lots of devices, it may be faster to try to fix the C7 port to do the cloud backup.
Fixing the port would also save the time in putting the devices back into apps, compared to re-pairing manually and then putting them back manually. So it really comes down to which method is quickest/easiest for user911 to deal with.
Thanks for the thread. Now I know the USB cable is fine; works on the grandkids' velociraptor,
Anyway, took the old hub apart, didn't seem to be anything wrong with the USB connector and the hub was getting warm but wouldn't connect.
I went ahead and paired everything up again and managed to find my old sound files so all working well except the keypad which I haven't tried to pair again yet.
Thanks for everybody's help and once I get that keypad paired, I will definitely get the cloud backup. Would have been a lifesaver,
