Maverick TimeMachine deletes old weekly backups with no reason

Hi,
I use 10.9.4 and I found that TimeMachine deletes old weekly backups so that there are now 14-days backups.
I see no reason.
To make it clearer: Old backups from 2014-04-18, 2014-05-02, 2014-05-23, 2014-06-13 and 2014-06-27 were deleted.
The log:

I was about to try this, but the problem was solved - by updating to ML DP3. Time Machine was able to report more specifically a UUID mismatch - which was strange as there had been no hardware changes:

Upshot is that after many hours it's back, and the sparseimage has been verified.
If it's of any use to anyone finding this, I would say that the solution seems to have been a Mac OS reinstall - which is counter-intuitive, but if all else fails, give it a go!

Apple deleted old iPhone backup :(

Hello!
I'm paying for iCloud and had an old iPhone4S backup at the cloud. Today, I decided to get back for iPhone, only to found that Apple deletes iPhone backups older than 6 months and my backup was near 9 months old.
I went very angry, because of some unique data I had with this backup.
Is there any way to restore it? Any chance for Apple support help?
Thanks for any help.

Unfortunately, I doubt it. You would have to contact iCloud support to find out for sure.
I assume that Apple does this because there are some 340 million iCloud accounts and a number of them are abandoned as people sell or stop using old devices, or create new accounts to use. At some point they have to clear out the old accounts to free up server space.

Can't Delete old iPhone Backup off of iCloud backup storage

After upgrading my iPhone 4S to a iPhone 5S, I restored the 5S using the recent backup of old 4S. Now I am getting "out of cloud storage space" messages on my new 5S phone. I went into iCloud backup storage to delete the 4S backup, but, it says it is in use and cannot be deleted at this time. I have attempted to turn off iCloud backup on the old 4S phone, shutting it off, turning off iCloud backup, but, get the same failed message when attempting to delete the old backup.
What is the trick to removing this without wiping the old 4S, because I want to be sure there is nothing left on the phone, before I completely wipe it...and I can't tolerate the "No more space in cloud storage" message that keeps popping up on the 5S.
Thank you,

That should clear up on it's own but may take 3-5 days to do so. Wait a few days and try deleting the old backup again. If you want to back up your phone in the meantime, manually back it up to your computer using iTunes (click Back Up Now on the Summary tab of your iTunes sync settings).

26 GB backup with no reason at all

Title says it all.
After one day of normal activity (few MB backup each hour) I suddenly had time machine performed a 26 GB backup.
I was doing nothing special, just was watching a long stream video on thoughware tv (youtube video), plugged an iphone
Does anyone know how to prevent thos again and claim the space back ?
If of any help: the logs shows an error for backupd 2 hours before (error -43), and a message:
"Bulk set MDS attrs failed"
However the hour before the backup was Ok
????

+By deleting the backup , you mean the entire folder that looks like+
/Volumes/MyDiskArchive/Backups.backupdb/MyMachineName/2008-01-10-230148
Don't use the finder to delete any backups as that will probably break the hard links that Time Machine uses to keep track of its previous backups. Delete them in the Time Machine browser instead. You can read about how Time Machine uses hard links in this Ars Technica review.
http://arstechnica.com/reviews/os/mac-os-x-10-5.ars/14
+Do you know if there's a way to see what will actually be deleted so that i can identify the cause ?+
Type "backupd" in Console's search window to see just the Time Machine log. Look in particular for any -8088 errors which are known to cause Time Machine to belch a nearly full backup. Those files should be deleted or excluded from Time Machine backups by going to System Preferences > Time Machine > Options. Drag the problem file to the "Do not back up" pane or use the "+" button to add it.
The log will also give you the information about the date, time and total size of recent backups. You can ID the belched backup that way.
+I had the same problem 3 weeks ago+
Time Machine retains the first backup made at or after midnight as its daily backup. It deletes other hourly backups after 24 hours. Unless the belched backup was the first backup of the day Time Machine has already deleted it.
Whatever the source of the problem might be please report this as a bug via Apple Care or by filing a bug report through Feedback.

Time machine Deleted old computer backups

Hey,
I have been using a mac pro for about a year and a half now and as all computers get it has become slow and full of garbage. So i used my time machine back up and successfully backed up all my files. I put in the OS disk and wiped the computer clean and reinstalled the OS. I plugged the time machine back up in and began to copy over only the files that i wanted. A few days later I had not yet copied over all of the files that I needed, i was prompted me to set up this computer with a time machine back up. I began the process thinking that it would create the backups in a new file on the drive or append it to the current list of back up images. It stopped half way though saying there was not enough free disk space. on the 1 TB HD there was only 5 GB remaining. So I just canceled it and was going to finish copying over all of the files i wanted and they delete the old backups. However when I went to get my old backup files, they had all been deleted.
I was using this hard drive to store other media files as well as time machine backups. taking the HD into the local computer shop i was informed that that is a terrible thing to do and perhaps the reason that my backups have been lost. the tech said there was nothing to be done but reformat the drive and start again. I am hoping this is not the case. the drive still says there is only 5GB of free space however I can only fine 300GB of files on the drive. so i believe that the files are still there. Does anyone know a solution to this issue. There are many valuable things on this hard drive that i would hate to loose.
I have tried holding the option key and clicking on the icon to view other backups, but my original backups are not there.
Thanks in advance.

Before I make any reply, note that you are responding to a topic that has been inactive for more than two years, on a system two versions out of date. In the future, you would do better to start your own topic in an appropriate forum, specifying what system you're running and what hardware you're running it on, among other things.
this exact thing happened to me as well and I must say that I find it totally unacceptable...
Well, without more information, it's impossible to say what might have happened or how you can recover. You may find some answers on Pondini's excellent site:
http://pondini.org
However, it's important to understand that this may or may not have anything to do with Time Machine. Perhaps your backup drive is dying, perhaps its directory structure became badly corrupt, perhaps one of any number of other things could have happened. Because there is no such thing as storage that is completely stable, it's important to keep more than one backup, as noted previously on this topic.
Carbon Copy Cloner seems like a much better solution at this time.
Carbon Copy Cloner is an excellent solution. Is it better? No. It is simply different, and that makes it better in some aspects and worse in others than Time Machine. The best backup strategy will involve two different backup programs. I frequently recommend using both Time Machine and CCC. I use TM with a Time Capsule for one backup, which has certain advantages over CCC. I use CCC for a couple other backups, one of which is in a safe deposit box at all times, and that has some advantages over TM. Using both, with multiple backups, means that I'm extremely unlikely to lose much data, if any at all... unless a meteor hits and destroys both my home and my bank, in which case I've got bigger problems!
Anyway, with regard to recovery, take a look at Pondini's site. If that doesn't help, or you need assistance with something, start your own topic in the appropriate forum for your system and provide additional details that may help us better assist you.

Two questions: getting first iPhone & deleting old iPhone backups?

Here's the deal.
My neighbor has 'paid' for his old iPhone 4 through AT&T and is getting a new one. He's going to give me his old one. It will be my first smartphone (and, naturally, my first iPhone). I've backed it up for him using my computer before and there are a bunch of his apps in iTunes which I would like to remove. So my first question is, "how do I get rid of that backup"?
I've downloaded the iPhone 4 manual with iOS 4.x (which he has running) and I think I know how to go about updating and resetting the phone. After I get it updated to iOS 6.x, I'll be going to the AT&T store and finding a good (cheap!) plan that fits my lifestyle.
Any help or suggestions?
Thanks,
Clinton

On the phone, follow the directions here:
http://support.apple.com/kb/HT5661
Then set things up using YOUR Apple ID. Any old backups, delete: iTunes>Preferences>Devices. Also delete any & all content, in your library, obtained with his ID.

Had a phone set up to back up to iCloud. That phone went dead, and was returned to Apple and exchanged with a new one. Because the screen went dead -- thus rendering the phone inoperable -- I was unable to shut off iCloud backups and delete the old backup.
Right now, I can't delete the old phone's iCloud backup, and I don't have enough space to start backups on the replacement phone. How can I resolve this?

If you registered your old phone with Apple, try unregistering it by:
Going to: https://supportprofile.apple.com/MySupportProfile.do
Loging in if not already logged in.
Clicking on ">" to the right of the phone listing
Clicking "unregister"
This may take a day or two but hopefully will then allow you to remove the backup.
If it doesn't, then one option is to create a new iCloud account and migrate your data to the new account. To do this, go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off. When prompted choose to keep the data on the iPhone. After everything is turned off, scroll to the bottom and tap Delete Account. (This will only delete the account from this phone, not from iCloud, in case you ever want to re-use the account in the future.) Next, set up a new iCloud account on this phone using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On. When prompted, choose Merge. This will upload the data to this new account.

How do I delete old TM backups after trying to drag to trash?

Before finding out that draging TM backups to the finder trash was a no no, I did it. Now I an not get rid of those files. I have a new TM backup . . . that's no problem . . . I just can't seem to delete the old files.

Take a look at this part of Pondini's Time Machine troubleshooting guide:

Gray screen after deleting old user accounts - with a twist...

I have two MacBook Pros w/retina displays. Purchased about 6 months apart, they are both running 10.8.4. The newer unit was recently bought from my employer (work unit) and connected to my wi-fi. I set up file sharing and deleted the work-related users accounts on both. When I rebooted, both went to gray screen, apple icon, and wheel spinning. Then icon only with no wheel.
Command-P-R to repair permissions and repair tasked 3-4 times - Same result after reboot.
Reinstalled OSX on work unit - SUCCESS and all my changes made before the gray screen were intact.
Reinstalled OSX on home unit - The install ran its course but after reboot, gray screen. Command P-R revealed that repair was available but repair permissions button is not grayed out. Repaired 2-3 times. Same result. Restalled OSX 3-4 times. Same result.
The files are intact...at least the space is showing utilized. My last option is to slave home unit to work unit and transfer all files then reinitiallize.
Help me Obi-Wan. You're my only hope.
Thx in advance! DC

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. The battery is distinct from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Deleting old computer backups

I need to get rid of the backups from my old MBP I have deleted lots via Time machine but available space on Time Capsule still only 45gb and backup bundle still shows 545gb how do i regain space.
I need to ultimately remove all the backup from the old MBP.
I have three computers backup up to the time capsule plus some other stuff, so would prefer not to have to erase everying on the TC.
Help anyone...

Time Machine "sparsebundle" files behave differently than a normal file. A sparsebundle grows as more data is added, but if data is deleted, the apparent size of the sparsebundle stays the same.
When more data is added that surpasses the original size, the sparsebundle starts to grow again. Simple, huh?
If you want see the actual available space, you need to "compact" the sparsebundle file using Terminal commands.....not for the faint of heart.
See #12, specifically the pink box in Time Machine --- FAQ by Time Machine expert Pondini.

Syching Old iPhone backup with New iPhone

I previously owned one of the original first generation iPhones, but that was recently stolen so I got a new 3GS for Christmas. I am syching it with my computer for the first time and iTunes is asking me if I would like to synch the new phone with my old phone's information. I need to know a few things before I can decide;
1. Will the syching process completely erase everything I have on my new phone currently in favor of the old backup information (ex. contacts, notes, calender events, pictures, ect)?
2. Would this be safe for the new phone, or would there be software problems between the different generations?
Thanks

A new iPhone is not synced with the backup for a previous iPhone. When connecting a new iPhone to iTunes that was used to sync a previous iPhone, you are prompted to transfer the backup for the previous iPhone to the new iPhone. This will transfer the backup for your previous iPhone to your new iPhone as of the time your previous iPhone's backup was update.
This link provides the data included with your iPhone's backup.
http://support.apple.com/kb/HT1766
After the backup is transferred to the new iPhone, this must be followed by a sync with iTunes to transfer the data to your new iPhone based on your selections under the various tabs for your iPhone sync preferences, which will be pre-selected for your new iPhone based on the selections you had under the various tabs for your previous iPhone sync preferences with iTunes.
1. Will the syching process completely erase everything I have on my new phone currently in favor of the old backup information (ex. contacts, notes, calender events, pictures, ect)?
Yes.
2. Would this be safe for the new phone, or would there be software problems between the different generations?
The current iPhone firmware version can be run on every iPhone generation - on the original iPhone, on the 3G, and on the 3GS.

Is it ok to delete old iphone backups

i have the latest backup for my phone and my wife's phone in itunes, prefs, devices. i also see one each from when we got our new phones on jan 5. is it okay to delete the jan 5 backup files now that i have a newer backup? is there a good reason to keep them? also, in finder, itunes, i have previous itunes libraries from 2009 to 2011, do i need these? what will happen if i delete them? thanks.

The manual iTunes backup process for my iPhone and iPad has stored multiple manual backups in my laptop's MobileSync backup folder. I thought iTunes only stored the most recent one backup. There are multiple files for each backup date and multiple backups going back for months. The iPhone backup folder has over 1.2GB of files in it. The iPad folder has .5GB of files in it. I have two questions:
1. Why is iTunes creating more than ONE backup for my iPhone?
2. Is it OK to delete the ALL of the older backup files (prior to the most recent backup date)?
