Apple device owners unable to restore from backup as iCloud outage continues [u]
An unspecified service outage that has been ongoing for nearly 36 hours is impacting a small percentage of Apple customers attempting to use iCloud Backup, prohibiting them from creating new backups or restore from previous saves.

According to Apple's system status webpage, the company's iCloud Backup service has been down since 8 a.m. Pacific on Tuesday. The downtime is ongoing at the time of this writing.
As its name suggests, iCloud Backup allows users to backup device settings, app data and other critical assets to the cloud for later retrieval. Like local backups to iTunes, device backups to the cloud provide peace of mind in the case of a drastic system failure.
More frequently, however, iCloud Backup is used to provision and move data over to newly purchased devices. For example, a customer purchasing a new iPhone might use iCloud Backup to transfer over saved device preferences, call histories, iMessage strings, App Store purchases and more from their previous device. iCloud Backup also handles Apple Watch backups.
Apple notes less than one percent of users are impacted by the outage, but with an install base of millions, that number runs into the hundreds of thousands.
The company failed to specify the origin of today's troubles, but it can be assumed that engineers are working to resolve the issue. Apple has not commented on the downtime and does not provide estimates as to when a fix will be in place.
Update: Apple resolved the issue at approximately 5 a.m. Pacific on Thursday.

Given all the hacking going around (the latest one having started yesterday), I wonder if there's something impacting some major provider of cloud services that we're not hearing about.
You will have to take care your Data Safety such as bit flop, HDD failure, ransomeware, fire hazard etc. I am not against having an own server. But seriously I want BOTH. I want a Time Machine that takes my backup first, and iCloud as my secondary backup.

"Apple and Google reached a deal worth between $400 million and $600 million to host iCloud and other data on Google Cloud Platform. "
I learned that back in 1977 -- after implementing a new computerized accounting system I was trying to do some historical reporting only to find that the historical data was gone. When I asked for it to be restored I found that they had taken three backups of it -- but all three had either failed or been lost or been accidentally destroyed...
THIS is the voice of experience:
2TB HDD
All I really care about on it are the 51,000 home photos on it from 2002-present.
I use Time Machine to a (cheap I suppose) backup HD (USB-2), a second cheap usb-2 hard disk with JUST the iphoto library (copied out every now and then), and then I rarely export *some* form to other outputs.
Would love to change the HD to SSD and give the iMac new life (it chugs in Photos), and have watched several youTube video's of the process (including the thermal-cable-stuff), but it's daunting.
Semi-Major surgery and High penalty for failure.
I've always tried to keep 2 or 3 copies around (through various methods), especially of important data. The cloud is actually great to be one of them, so long as a 'sync' process doesn't go awry and erase something, extremely efficiently across all your devices (my main fear regarding Apple's cloud).
What I've not been happy with, is that in the process of trying to make iOS simple, they've made it incredibly hard to do good and regular backups, manage data, and retrieve/restore data apart from whole-device-state type operations. That's actually one additional reason I'm hesitant on the whole iPad replacing laptop thing, even given the power and advancements of late.
Resolved.
One hint I used was to keep the iMac standing upright on it's stand during the entire process (unlike what iFixit says). Makes it easier to get to and unplug the various cables when removing the display. Watch the OWC video about opening your model.
