Ipad (3) wont backup with Computer or iCloud

Question

I plan to update my ipad, but before I do I need to backup. Only problem is any attempt to backup fails.
On windows using itunes, the backup starts and then when it nears 100% complete it says ...
iTunes could not backup iPad "name" because the backup could not be saved to the computer
So, I'm using Win8, latest iTunes, new computer, firewall off, etc. etc. I spent 2 days trying this with no success. Looking in the iTunes logs directory under %appdata% all I see is the following:
[4736 @ Mon Sep 23 21:55:10 2013] [com.apple.console AppleMobileBackup.exe] Unable to move temporary file "C:\Users\<blah>\AppData\Roaming\Apple Computer\MobileSync\Backup\Logs\MobileBackup-unknown-20130923-215510-Backup-Com puter.log" (3)

[4736 @ Mon Sep 23 21:55:17 2013] [com.apple.console AppleMobileBackup.exe] ERROR: Backup error: -30
Next step, fall back to iCloud backup directly from the iPad. I do not have a lot of data on it, so this should comfortably fit in the available 5GB. Unfortunately it never completes estimating time remaining and basically bombs out immediately.
Any help appreciated!

Whyohy,
I had a similar issue.  I was neither able to back up to iCloud nor to my computer through iTunes.  When I tried to do so to my laptop, iTunes would display the following message:  "iTunes could not back up the iPhone [myiPhone] because the back up could not be saved on this computer."  I looked at the system log and saw the same error as you.  When I tried to do so to iCloud, my phone would display the following message:  "The last backup could not be completed."
On my laptop, I did the measures suggested by this article:
http://support.apple.com/kb/TS2529?viewlocale=en_US&locale=en_US
None of that worked.
On my iPhone, I tried the following:
Turning off backing up for the camera roll.
Deleting the backup for the iPhone in iCloud.
None of that worked.
I did not want to do a factory restore, so I decided to contact Apple Support.  My case got escalated to a senior advisor.  He suggested that I turn iCloud backup off (Settings > iCloud > Backup > iCloud Backup) and reset all settings on my iPhone (Settings > General > Reset > Reset All Settings).  Once that was done, I reset my phone (press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo) and reenabled iCloud backup.  I was finally able to back up both to iCloud and my computer.  Fortunately, all of my content was preserved.
I hope this helps.
