How to solve 'An error occurred while backing up this iPad (-35)' when trying to update to IOS 5?

My iPad (first generation) is currently on 4.3.5. I have been trying to upgrade it to IOS 5 several times since IOS 5 release but keep on getting the following messages:
I press CONTINUE and get:
and MORE INFORMATION gives me http://support.apple.com/kb/TS1275
I cannot find error -35 and I've tried everything that has been suggested. Any help would be appreciated (had no problem with my iPhone 3GS upgrade).
Many thanks in advance!

So you used your own manual back up after updating , and that worked?

An error occurred while backing up this iPad (-5000)

I'm trying to update someone else's iPad for him. Windows XP Home computer. Latest version of iTunes. The iOS 5 file has downloaded from Apple. When I start the upgrade, first step is a backup of the iPad. I get maybe 4 green bars on the progress window and then get an error message that states "An error occurred while backing up this iPad (-5000). I stop at this point.
Apple KB has a long list of error numbers for this message, but not -5000.
Any ideas?
Thanks.

I had the same issues. My computer runs Windows XP Media Center Edition. The itunes update downloaded easily but i received the -5000 message when I tried to update the Ipad software iOS 5. After many, many unsuccessful attempts to correct the problem, I disabled my Norton Antivirus and it worked without any more snags. It still took about another 45 minutes to complete the install but there were no more errors.
To sum it up---DISABLE YOUR ANTIVIRUS SOFTWARE--and that will probably fix the issue.

I am getting an error when trying to update my wifes gen1 iPad from 4.2.1 to whatever is the latest:
"An error occurred while backing up this iPad (-500).
Would you like to continue to update this iPad?
Continuing will result in the loss of all contents on this iPad."
Any suggestions?

Based on this article, it looks like you've had a communication issue with the iTunes Store (note where the -5000 error appears):

An error occurred while backing up this iPad (-43) iOS5 update

While updating to iOS5 the process stops and error message "An error occurred while backing up this iPad (-43), would you like to continue to update this iPad? Continuing will result in the loss of all contents on this iPad"
If i select no and manualy do a backup and sync it works fine ... so a back up is there. Its the new update/ itunes process that is failing???
Anyone else having this problem?

An error occurred while backing up this iPad (-43), can't upgrade to IOS 5

As per title, my XP was just upgraded to iTune 10.5 and the itune music library was also successfully relocated to another drive to make room for the upgrade preparation. According to the pre-upgrade message, my ipad backup just need ~9G space while the space is about 13G. However, there was still system error message as mentioned after 5 minutes of backup. I stopped the upgrade then.
Any idea about error code (-43)? Tks in advance.

"An error occurred while backing up this Iphone (-50)"

Hello all,
I've downloaded IOS4 and am trying to upgrade by 3G, but when I hit the upgrade button, I'm told repeatedly that there's an error backing up the Iphone (-50). I've reset the Iphone, turned off my firewall, rebooted, but I get the same message.
The thing is, I remember several months ago that my syncing was taking an hour every time because of the back ups. (I keep a large amount of data in a third party app.) I came here and learned how to prevent my 3G from backing up every sync, and my syncs have gone really fast since then. The problem is that I've forgotten what I did or how to change the settings. If I right-click "Iphone" under "Devices" in Itunes, I don't get any option to create a backup, nor can I find any "backup" command anywhere in Itunes (latest version).
I can't even figure out where to go (assuming there is a place to go) to check when my Iphone was last backed up. Itunes is giving me the option to go ahead and update without a backup, but I don't want to do that until I at least know when was the last time my Iphone was backed up.
Can anyone tell me (a) where to go to check my backup history, and (b) how to get my phone to back up, assuming that it's not doing so? Thanks!

The same thing happens to me.
I've tried two times to upgrade to iPhone OS 4.0, leaving the phone offline and syncing for 10 hours... the backup proceeds sluggish and about 5% it stops with the message:
"An error occurred while backing up this Iphone (-50)
Would you like to continue to update this iPhone without backup?
CONTINUING WITHOUT BACKUP WILL RESULT IN THE LOSS OF ALL CONTENT"
If I try to Continue another message says:
"The iPhone could not be updated because the firmware file was corrupt. Disconnect and reconnect, then try again."
I've never even tried to hack or jailbreak my iPhone, and everything was normal since I try to upgrade to OS 4.0
This is my equipment:
- iPhone 3G 16GB (14.64 full), sw 3.1.3
- iTunes 9.2 (61) running on Snow Leopard 10.6.2

An error occurred while backing up this iPhone (0xE800002E).

I know this question has been asked for a long time and I googled it to death but not sure if the fixes apply to my situation plus most replies were from 2008! I am trying to update my iphone 4 to IOS 5 and have done the normal sync and updates and clearing out some trash from itunes to ready my phone - that all seems to go just fine. Now the problem is when I try to update, it will start out backing up the phone and after awhile i get this error
"An error occurred while backing up this iPhone (0xE800002E). Would you like to continue to update this iPhone? Continuing will result in the loss of all contents on this iPhone."
From what I read this is an error due to an app, but which app i have no idea - I have about 300 on my phone! I'm not sure if i should continue and then restore. I guess basically I'm looking fo rthe best advice as to how to proceed. I'm somewhat iphone proficient, but please be 'simple' in your responses as I"m 40 weeks preggo so concenttrating is no easy task
thanks!

I hadn't read that article, so am i to assume that the IOS5 install will erase everything anyways... so if I've sycned my iphone already and then continue with the update AND hit continue losing all contents it 'shouldn't' matter?
"An error occurred while backing up this iPhone (0xE800002E). Would you like to continue to update this iPhone? Continuing will result in the loss of all contents on this iPhone."
i have not seen the window they showed there in the article.

IOS5 UPGRADE HELP! An error occurred while backing up this iPhone (-50). Would you like to continue to update this iPhone?

I've been trying to upgrade to iOS5 for the past half day. I keep getting:
"An error occurred while backing up this iPhone (-50). Would you like to continue to update this iPhone?
Continuing will result in the loss of all contents on this iPhone."
I think I have been on every forum the Internet has. This means:
-Yes, I have tried restarting my computer
-Yes, I have tried using a different USB port
-Yes, I have tried doing the whole DFU mode thing
-Yes, I have tried freeing up some drive space from both computer & iPhone
-Yes, I have tried removing MobileSync folder from AppData
-Yes, I have tried Airplane mode and Bluetooth Off
-and Yes, I think I have waited long enough....!
Please help.. I'm hopeless. lol.. and no i dont want to lose all content on my iphone

This is the correct steps to solve this problem:
1. Cancel the update (with the backing up error, of course)
2. Do a manual backup
3. Do a manual restore (your password to unlock your backup file is your AppleID password, not your IPhone keypad password)
4. Now Update your phone. This time the backup should work.
5. After it is updated, it will automatically restore, if you choose to restore not to set up a new phone.
And yes, copy all your photos manually. Your backup probabally won't include photos.
If this still doesn't work, try to stop your anti-virus software.

An error occurred while backing up this iPod (-120)

I have an iPod Touch 2G that I'm trying to upgrade to iOS 4. Every time I try, I get the message:
*An error occurred while backing up this iPod (-120).*
*Would you like to continue to update this iPod without*
backup?
Coninuing without backup will result in the loss of all contents on
this iPod.
Now, I don't want to lose all the contents so how do I fix it so the backup doesn't fail?

Its not any hardware issues
i have 1395GB free on my harddrive and it wont backup or transfer anything from my ipod.
Its more of a software issue
once you attempt atleast once to install iOS4 a bunch of data will be left behind from the install even if it fails. Itunes is very buggy and the iOS4 update is glitchy specially with ipods. I have tries twice and itunes really isnt cooperating with my ipod
its constantly freezing my ipod with that little spinning circle.
So i myself am also waiting for a later release/update of iOS4 and itunes until ill update my ipod
this release isnt stable or safe at the moment, so id recommend you also wait a week or two or until a few days after apple releases their iphone 4 since there will be lots of traffic blocking their servers. I downloaded and saved the 4.0 os update to flashdrive just incase so i wont hve to download it again :]. but yea
id say do a factory restore to 3.0 or 3.1.x or if you had it earlier than 3.0 go to 2.0? Then update to 3.0
rhen update to 4.0 instead of installing 4.0 with apps an stuff cluttering the device install. If you can, email all your photos or whatever you need to yourself, and write down all your songs and apps And bookmarks, then erase eerything and install os4 then reinstall all your apps and music and pictures.
But my final advice would be to just wait it out. When 2.0 and 3.0 were released they messed up many ipods by messing up their wifi and firmware, and later on with the later updates it could not be fixed, so id say first install a good release and not just regular 4.0.0 id say wait atleast until 4.0.1 and a itunes update
this should fix everything, the problem is that they rushe it into production and ddnt test enough apparently.

An error occurred while backing up this iPhone (-402653081). Would you like to continue to update this iPhone?

I don't understand this error. I have gotten it at least seven different times while trying to update to iOS 5.0. Can anyone help me? It asks if I want to continue, but says that if I do all data will be lost.
An error occurred while backing up this iPhone (-402653081). Would you like to continue to update this iPhone?

I solved my issue.
She had a ton of photos & videos on her phone. I manually moved those off to the phone and on to the computer.
I went into iTunes preferences/devices and deleted all but one backup of her phone (kept the latest one just incase). Then I did my own backup by right-clicking the phone in iTunes, on the left side.
Then I selected the update, let it fail and proceeded to update it knowing it was going to erase ALL data. Once it was done restoring, and updating to i0S5, I restored from backup successfully.
Everything was there, Aps, Contacts etc.
Hope this helps someone.

Error occurred while backing up this iPod (-50)

How's Life?
While trying the ios5 update, I receive the following message:
iTunes
An error occurred while backing up this iPod (-50).
Would you like to continue to update this iPod?
Continuing will result in the loss of all contents on this iPod
Continue Cancel
Thankfully I did my iPod touch first (didn't read the unbolded 'loss of all contents'), because when I hit continue it erased my touch and put ios5 on it.
We can right click both my "new" touch and her ios4 touch, neither have the backup option to start/create a backup.
We can do edit/perferences/devices and there are no backups listed.
Any suggestions?

Am using windows 7
Closed itunes
start/pearl
pasted this command:
"%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt DeviceBackupsDisabled 1
and enter
restarted itunes
and all is well again.
Looks like -50 also means that itunes backup has been disabled
