iCloud backup size "0 KB"-- what does this mean?

There's nothing embarrassing about it. It's just the way it is. As has been established several times in this thread, it is merely cosmetic. Your backup is there, and you can see the backup reflected in iCloud.com.

You have an older device running an older iOS. I have an iPad 1 running iOS 5.1.1 that says the same thing. It backs up nightly, and I have restored it several times.

I was instructed by Apple support to either

- update to latest iOS 11... from 10... or

- backup using iTunes

For me updating the iOS solved the issue.

If your iPad is actually running iOS 10, and it is no longer showing in iCloud.com under Settings, then you should try signing out of your iCloud account on that device and then signing back in. Doing that may not only clear up your issues with the device not showing, but may also clear up the 0KB issue.

Best of luck,

iCloud backup is fine. It appears that for some older iOS's the backup size is showing as 0Bytes under the Last Backup. But, it is, in fact all there and in tact. You can look at any other iOS device that is backing up to the same iCloud account, go to Settings>your name>iCloud>Manage Storage>Backups, tap on the device that is showing 0 Bytes elsewhere, and you will see the accurate size of the backup for that device.

Just to make sure, I would recommend that you create a current backup in iTunes on a computer to make sure that what you have now is safe.

Then, I would erase the device and restore it from yesterday's backup. You should be fine. I've never yet had a backup that did not back my device up to exactly where it was at the time of the backup.

When you go to Settings>your name>iCloud>Manage Storage, tap on the device in question, and you should see the actual backup size there. I know you looked at it on your Mac, but also see what you see on the device itself under the iCloud Storage path above.

And, just so you know, I did actually do this with one of my own devices (my old iPad), and everything restored with no issues (just a few with the Two-Factor verification and a place to put the verification code, for example), but the restore itself, worked just fine.

So, here are the instructions:

Hi all- just wanted to report that I took the plunge and wiped my iPhone 6 and restored it with the 0KB iCloud backup. Yes, in a fit of extreme paranoia I (a) also backed up my phone in iTunes on my macbook and (b) I emailed myself all my saved voicemails and notes (I know, I'm nuts). Everything went fine. Took less than an hour to restore all my apps (I have way too many!) and the only things I lost were all my Touch ID fingerprints and all my keyboard shortcuts. All my "mysteriously disappeared" texts were back, all my settings were fine, all the email accounts and apps and their data restored. And, it did NOT ask my to update to the newest OS, which I kinda don't want to do (I don't love some of the changes). Yes, it was SCARY - I braced myself to be left with a bricked phone or a "like new" phone with no history. A big thanks to Gail from Maine for all your patient hand holding. Many blessings Gail! : )

After restoring my phone, and backing it up several times since, on my phone the back up size still shows as 0 kB. However when I look at my Apple iCloud ID, I can see that there's about a two gig back up up there.

The only way to submit feedback: Apple - Feedback. They read all feedback, but do not respond directly to it. It appears to be a cosmetic bug, and I'm fairly certain they are aware of it.

Did you get your iPad backed up to iTunes yet?

Thank you thank you thank you!!!! I've been having this problem for forever! But now that my mom had it as well I really needed to get to the bottom of it, and you were right, and wheEn I used my phone 6s+ I saw my ipad4's backup and it had a numerical value that ws not "zero" or "0kb"! Thank you soooo much!! So I'm sure when I get her phone it'll be the same thing. You're a lifesaver!

I am seeing the exact same thing. I coincidentally noticed it today while checking to see that all my devices were backed up. I hope that this is a temporary problem and that the backups are actually being done.

I'm seeing the same thing. Zero KB for the size of the current backup. The size of the next backup takes forever to appear and is ten times smaller than it should be. The storage graph for iCloud shows a different amount used by backups on each device. The backup status for some devices (not all) shows as Unknown on other devices, although it still shows the time of the last backup.
