I'm having the same issue. Neither my iPad nor my 7+ will backup; both devices are 256GB with about 200GB used, but I have more than 1TB available on my iMac ...Run the command below in Terminal and give it a couple minutes to complete, then post the output here for us to look at. It will show how much space is being used on the drive, including hidden and system files. Also tell us the size of the drive.
Code:sudo du -d 1 -x -c -g /

Right. And yet, neither the iPad nor the iPhone 7+ are able to backup. iTunes continues to give the 'not enough space' message ...Assuming you have a 3TB drive then (?), I don't see anything wrong. Looks like you would have plenty of room to backup.
But if I do that, my health data won't be backed up - the health data is the only thing I'm interested in backing up. 🙂 I have a launch day Apple Watch, which means I've got a year and a half of activity rings and achievements, which I don't want to lose! Nothing else really matters, because it's all backed up in some other way (pics are iCloud Photos, music is iCloud plus Apple Music, both are backed up completely to an iMac which is itself backed up to Time Machine, Backblaze (online backups) and quarterly Carbon Copy Cloner backups. So, yeah - the health data is the only thing I need to backup on the phone, and the only way it will backup is with encryption turned on.I think this problem is related to encryption on your iPhone. You need to disable it.

Thanks for the reply! Actually, Apple fixed this bug some time ago, so everything is working now! Aside from the fact that some notifications seem to disrupt my sync, anyway - but at least it works in airplane mode.Maybe try turning encrypted backups off, complete a backup. Then turn encrypted backup back on? As long as you don't erase your iOS device, your health data won't go anywhere...
Also, if you backup via iCloud, your health data is saved that way as well.
