Identity of Backup has changed..umm, no it hasn't

I've been backing up for more than a year on my trusty Time Machine, sometimes there are hiccups but mostly it is seamless. This morning, "The identity of the backup disk has changed since the previous backup." Sorry, nothing has changed on my end. Nada. Nothing. Tells me "The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk."
So, I choose "Use this Disk" (other option was Don't Back Up). But it "fails."
What to do, what to do? Is some pirate out there trying to swoop in and steal my data?
Can someone help me get my head out of the oven?

I have a Mac Mini, MacBook Pro and a IMac that all back up to the same Time Capsule. All worked fine for months and then the IMac started displaying this message. The other two are fine.
I finally let it create a new full backup (sparcebundle) and it worked fine for a week. Now I am getting this message again.
Sometimes if I disconnect all users under the disk tab in Airport Utility, and do a manual backup it will work fine. Sometimes not. Very strange.

Time Machine reports identity of backup disk has changed

Hello! A few weeks ago I purchased a new 15" Retina MacBook Pro and a new 2TB Time Capsule. Every day or two I get an error informing me that the identity of my backup disk has changed. I finally got sick of this so I turned off Time Machine, deleted the preferences file, wiped the Time Capsule drive, and restored the Time Capsule settings to factory, and started fresh. However, I'm still seeing this error.
Some minor details: The Time Capsule is named "AirPort Time Capsule," as is the volume on it. I initially had a second hard drive at my office configured as a second Time Machine target, but after I started fresh with Time Machine, I didn't set up the second target, and am seeing the same message. I am also using Encrypted Backups.
Any suggestions would be great, I'm not sure if this is a bug in Mavericks, a bug with my Time Capsule, or something indicative of a hardware issue either at my MBP or my Time Capsule.

Any one of those is possible, and you have taken reasonable steps to resolve it. I suggest deleting the following file, which will reset Time Machine. Turn off Time Machine first, and make sure a backup is not in progress.
Triple click to select the entire line, then control-click and select Services > Reveal in Finder. Drag the selected file to the Desktop, or directly to the Trash:
/Library/Preferences/com.apple.TimeMachine.plist
This will not delete your existing backups.
Turn on Time Machine and reselect your backup volume. The effect of deleting that file will cause erroneous values to be shown in the "backing up xxx of yyy" messages until the subsequent backup.
If this does not resolve the problem contact AppleCare because you should not be having these difficulties.

"The identity of the backup disk has changed..."

About 3 months ago I purchased my new MacBook Pro plus two WD 2TB network drives for Time Machine backups. One drive is kept at home and the other is at my office. (I believe in having backups at two physical locations.)
The drives at both places are identical, with identical names and in both cases are connected to a BT router/DSL modem.
All has been working nearly perfectly. (I say almost, because occasionally at home I'll get an error saying a backup couldn't be made because the disk wasn't available. Usually this clears up after a few subsequent attempts, or always after a reboot. Fortunately this doesn't happen often.)
However, I'm now getting an error message every time I move from one location to the other:
"The identity of the backup disk has changed since the previous backup.
The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk."
Fortunately, the dialog box is very visible and gives the option of going ahead and using the disk...which I do. As long as I'm in the same location, everything then continues to work without issue.
This is most odd, as neither disk name has been changed and I was working for 3 months without anything like this happening.
(I might add, with my previous Powerbook, I had an identical Firewire drive at both locations and having the dual backups worked flawlessly without issue for the entire time I used it...nearly two years.)
Anyone have any idea why this weird message is now surfacing after 3 months of working fine?

There was a thread here a few months ago with a very nasty problem, where a user had 3 or 4 identical WD externals, with different names, and was trying to use one with Time Machine. But Time Machine would try to back up to the first one connected, regardless of name!
I didn't think it was possible, but sure enough, they all had the identical UUID from WD (they'd come formatted for a Mac, and the user had never reformatted or erased them, so OSX never put new UUIDs on them).
I wonder if the UUID would be copied over if a disk is cloned? When using my first pair of external LaCie Firewire drives, I first set just one up as a TM backup. After the setup and first backup was finished, I used Carbon Copy Cloner to create an exact duplicate to the second drive. I did that deliberately in hopes TM wouldn't be able to tell the difference. It apparently worked as I could connect either disk and Time Machine would readily connect without complaint. Either the cloning procedure worked, or perhaps the drives already had identical UUID's as happened with the WD drives you mentioned. Any thoughts on this?

If you haven't, try turning Time Machine OFF before you get that message. Then select the NAS via Time Machine Preferences > Select Disk. I think that will reset the element in the plist mentioned in that thread, and the problem will go away.
I went ahead and tried this, but the condition still persists. When I have a chance, I'll go back and look at that other thread and see if I can glean anything useful from it. In the meantime, I may just have to live with the current situation. Thanks.

Message "Backup disk identification has changed since the last copy"

Hello!
I have MD033 Time Capsule and my iMac 2012 and MacBook Pro connected to it. Time Machine is set to backup @ this disk.
Every once in a while I get the message you see in attach on my machines. Approximately it means "Your backup disk identificator has changed since the last backup (Possible reason the disk was changed or erased since the last backup or someone is trying to make you make aт illegal backup not on your disk "
I get this message from time to time both on iMac and MacBook but not simulateoneously. Once in a week or a month.
I already reinstalled anew systems on my machines and even replaced time capsule itself to the same model (absolutely new, factory sealed), not even mentioning formatting its disk a dozen times and resetting TC.
Does someone have same problem? Russian support couldn't help and directs me to a repair. But I really doubt that BOTH MacBook Pro and iMac have EXACTLY the same problem with TC. Everything seems as it is a software problem with some of the program

today, my MacBook shows a Message "The identity of the backup disk has changed since the previous backup."
Welcome to Apple's discussion groups.
It may not show anything useful, but try this: Disconnect all external and network volumes. In the Finder invoke the menu option Go > Go to Folder. In the resulting field type "/Volumes" (without the quotes) and click "Go". In the resulting window you should only see entries for any internal volumes. If you see anything else, particularly an item with the same name as your Time Machine volume, you may have the problem described in this article:
http://db.tidbits.com/article/9620
You should trash any such things. The way to prevent this in the future is to prevent any process from running that would write to external volumes that aren't mounted. For Time Machine, turn it off, then when you want to back up, mount the Time Machine volume and choose "Back Up Now" from the Time Machine menu item.

Time Machine, identity back up disc has changed

Using Time Machine I got the message 'identity back up disc has changed'. Time Machine doesn't make any back up. Cleaning back up disc (7 times!) doesn't make any difference! I have to choose another disc in Time Machine! But why??? How do I repair the identity (I didn't change it) my disc and will it be ready for back up again?

I have just upgraded to Mavericks and have been using Time Machine on an external disk with Snow Leopard. Can I continue to backup with Time Machine on the same external disk or do I need a new disk since the operating system has changed?

I have just upgraded to Mavericks and have been using Time Machine on an external disk with Snow Leopard. Can I continue to backup with Time Machine on the same external disk or do I need a new disk since the operating system has changed?

Hi there,
I found that Time Machine in Mavericks will sort it all out for you. You shouldn't need to buy another backup drive, unless you have insufficient space left and can't afford to delete whats on there. It should just work fine.

After Snow Leopard 10.6.2 TM appears to backup, but nothing has changed

I went to find a backup copy of a file and noticed that all hourly backup times are available but nothing has changed or actually backed-up since OS upgrade. Console error log says this.
12/3/09 11:07:31 PM com.apple.backupd[52779] 2009-12-03 23:07:31.619 diskimages-helper[54176:2103] Error loading /Library/Plug-ins/DiskImages/NUMPlugin.bundle/Contents/MacOS/NUMPlugin: dlopen(/Library/Plug-ins/DiskImages/NUMPlugin.bundle/Contents/MacOS/NUMPlugin, 262): no suitable image found.

12/3/09 11:07:31 PM com.apple.backupd[52779] /Library/Plug-ins/DiskImages/NUMPlugin.bundle/Contents/MacOS/NUMPlugin: mach-o, but wrong architecture
I moved this /Library/Plug-ins/DiskImages folder to the trash and TM is working again. What is that package for and can it be safely deleted? Why did it get corrupted?

this is not part of OS X. this is a plugin installed by some 3rd party app you have. I don't know which. google indicate that it could be Norton AV. do you by chance have Norton?

Find what has changed in backups

How does one find what has changed on the backups. When I click on a backup it shows user finder window. eg: In sys timemachine window/options, I choose not to backup applications. When I click on timemachine in dock it show the last one I did with this setting. click on side bar under user/application and it shows all apps. I would think it would not show anything because I told it not to backup applications.
Maybe I am just dense...

1. open Terminal
2. cd to the directory containing the timestamped backup folders. This will be /Volumes/<yourbackup_drive>/Backups.backupdb/<your_computername>
3. run the following:
sudo diff -qrN firstbackupdir secondbackupdir
e.g.
sudo diff -qrN 2007-11-20-172936 2007-11-21-111113

How to insert data into a table only when data has changed its value (when compared to the previous inserted value)

I wish to insert data into a table only when the value of the inserted data has changed. Thus, in a time series, if the value of the data at time, t-1, is 206 then if the data to be inserted at time t is 206, then it is skipped (not entered).
If the value of the data at time t+1 is 206, it is skipped also; until the value changes, so if the value at t+1 was 205, then that would be inserted, and if at time t+2 the data is 206, it would be inserted too.
What is the best way to do it without increasing overheads?

This view works:
SELECT
i.IDNO,i.[Date],i.[Level]
FROM
mytable i
INNER
JOIN mytable
d
ON
d.IDNO
= i.IDNO-1
WHERE
i.[Level]
<> d.[Level]
on this mytable below. A trigger could be quite useful here although I am cautious using them. However I wish to avoid the overhead by not having a temp table (which could be sizable). mytable below
should give 3 lines. The IDNO is an identity column.
IDNO
Item
Date

Please help me, I gave my information out to a person and he has changed all my information and now I can't get in.. I know the persons name

Please help me, I gave my information out to a person and he has changed all my information and I can't log back in.
Adrian Lee is the person I gave it to.
He told me to email him my information so he can level me up in the game Clash of Clans so I did and he changed all my information and I told him to give it back via email and he refused but suggested to restore my iPod and it would go back to normal and I dis, I nearly lost everything since I haven't backed it up for a while and I'm a Music Producer, this password is my paycheck, my food, my rent, my everything, now I'm not sure if this is the right place to go to but please help me. i'm begging you to please restore my password.. I'm not asking for anything of what I lost back, just my password so I can change it, get my things back and move on with my life. I have really back anxiety attacks. Please. I'm begging you. You guys are my last chance..
<Emails Edited By Host>

If you can't contact the person and get the information back then:
- Contact the police for help
- Restore from backup.
If you can't get it from the person or from a backup then it is lost.
In the future be carrful about who you give your login information to.

HT1918 I can't seem to update my apps or make any purchases on from my account. Nothing has changed with my credit card information and for some reason the iTunes Store tells me my information is incorrect. What do I do?

I can't seem to update my apps or make any purchases on from my account. Nothing has changed with my credit card information and for some reason the iTunes Store tells me my information is incorrect. What do I do?

Yes, it's frustrating.
I don't have my iPod with me but, as I recall, the change is done in Settings/Store. That change will apply to NEW purchases. However, be aware that all purchases are permanently associated with the Apple ID that was originally used. Generally, it's only a problem when you need to update an app. IF you do your updating from iTunes and your logged in to the "wrong" ID, you'll need to log out and back in again. It's easier from the iPod as you do not need to log out/in but you do need to know the password.
Unfortunately, you can not merge IDs nor can you transfer purchases from one ID to another. Go here to find out exactly what you have. I have the same problem so I deliberately made both passwords identical to make things slightly easier for me.

Itunes has changed the way it stores files over the years and now i am having trouble figuring out which files are where so I can back them up

Hi
I have backed up itunes by copying my itunes file to an external hard drive. I try to keep my large media files (like TV shows) in a separate folder so that I can keep my hard drive on my macbook from filling up. Problem is, apple has changed the way Itunes is organized and backs up over the years. Now I am having a hard time keeping straight what is where. When I go to support, it has different instructions for the various versions of itunes. I am using version 10 now but it seems like I can't see all my files within the itunes music or media folder. I want to get everything in one place so that I can easily back up, regardless of which version of itunes I am running at the time.
I have selected to let itunes organize my files. It keeps all the files I have purchased in one place apparently, but items I have imported don't seem to always be there.
How can I best sort this out?

I have, but if I don't have that particular external hard drive connected when my time machine backup hard drive is connected, then I don't think it is all backed up together. It is getting too complicated to get out all this equipment every time I want to buy some music.

Itunes will not open on my computer the icon on desktop has changed to a white foldertype icon. itunes is listed in programmes on my start menu but will not launch either

please help
itunes will not open on my computer the icon on my desktop has changed to a white folder and it is still listed in start programmes but will not launch i am concerned about losing all my downloads

You music etc should not be affected by problems with the iTunes program, nevertheless it is always a good idea to backup your data.
You haven't said if there was any error message when you tried to start iTunes. If there was one please give it in full.
Also check to see if QuickTime works, iTunes can not work without it. If QuickTime doesn't work, it has to be fixed before worrying about iTunes.
Then restart your PC and open your Task manger and select the Processes tab.
Try to start iTunes, does iTunes.exe appear on the processes tab? If so does it disappear again or remain although the programs does not open?

Ask your question.please help itunes will not launch on my computer the icon on desktop has changed to a white folder no error message appears and it appears but then disappears in task manager when the programme will not open quick time is working
