Um that may absolutely nothing to do with iCloud, it's services etc...
My iPhone 6+ took some days to finish restoring from a backup...
Why?
I had 9000 photos, videos, etc at 40 gb...And one app was corrupted...Should I blame Apple for everything? Are they now too responsible for the viability all of my content, every single file, every single app, the web traffic at the time, your ISP's BS, etc etc etc?? Seriously.
People, its' OVER THE AIR... Do you expect miracles??
Btw -- restore only works if you LEAVE THE PHONE ALONE. If you are using the phone constantly -- like you can't put it down since its a new device, we've all been there -- that delays your backup completing.
In the scheme of things...take my iCloud -- I have an iPad back up, a 5s back up, a 5c back up, a 6+ back up, all under ONE iCloud account... Less than 3 years ago this was unheard of, so I think they are doing a pretty damn good job being able to manage my 9000 photos, videos etc and get them back onto my device OVER THE AIR....
No need to go ape over my post
- I restored my iPhone 4S with this same backup last week (on 8.0), I also restored an iPad 3/Retina (on 8.0.2). This hang didn't occur on either.
- What has my ISP got to do with anything? My older iPods sync music and photos fine, there's a 34 page thread on the support forum about syncing problems introduced in iOS 7 that still haven't been fixed. I'd say it's down to Apple to at least make sure what used to sync fine in iOS 6 works in 7 and 8. Don't you agree?
- What's over the air? I'm doing this via iTunes, I thought the outage might be affecting authentication of my account. Please don't make assumptions about me.
- I have been leaving it alone? Please don't make assumptions about me. First restore when I got it: perfect, iPhone 4S and iPad 3 restores: perfect. Last few hours: not working.
I'm gutted to see Apple falling apart so much recently. It's like quality control and testing have just gone out the window.
