Time machine could not complete the backup of... The backup disk image could not be found (error (null))

Running OS 10.11.3 on my early 2011 Macbook Pro 2.7 GHz Intel Core i7 with 4 GB 1333 MHz DDR3, use Time Machine to back up to my Airport 802.11ac purchased 16/09/2014:

Backup failed: Time Machine could not complete the backup of... Airport Time Capsule.   The backup disk image ' / Volume/Data/MacBookPro.sparsebundle ' could not be found (error (null)).   Last successful backup: yesterday at 12:17

I can see the airport and the data file in my network.

I immediately did a full time Machine backup on a USB key and it disconnected from my system.

I unplugged the airport, let it rest for a minute and returned the power plug, let it settle for a green light.  I'm restarting Time Machine backup to the airport.

I need to replace the airport?  The appliance starts to fail?  Or, it is more likely is a problem with winter static electricity that has damaged the image and reconstruction will fix all this.  Reconstruction will take about four hours with no guarantee that it will work.

  • my time machine just to complete a backup, but it is not listed?

    I have three macs backed up on a time machine. The mac, I want to migrate was on the list, but I made a new backup to get the latest version. Now that it's over, it is not on the news on the time machine. No idea where it went? It drives me crazy.

    Your question is unclear.

    I have three macs backed up on a time machine.

    You mean a Time Capsule? They are backed up by Time Machine on every Mac.

    The mac, I want to migrate was on the list, but I made a new backup to get the latest version.

    Mac that you want to migrate from appeared in the Finder with a sparsebundle? It's still there... Have you opened it manually and check the dates?

    Now that it's over, it is not on the news on the time machine

    Sorry now it gets too complicated... did you really mean Time Machine here?

    If the Time Machine works normally... hourly backup you would not need to do anything special, so I'm lost exactly what you're doing different.

    No idea where it went? It drives me crazy.

    Me too.. I don't know where he's been... because I don't know what that means, or it you are talking about.

    Missing the sparsebundle to the backup?

    It is simply not enough the last backup date?

    Backup details will be in the paper... you can go through it and find out what happened.

    If you are migrating to a new computer before get rid you of this computer... Just use migration between the method of computers... not the method of TM. Transfer works very well... better even... If you connect two computers together through ethernet (love at first sight would be fantabulous)... and transfer on the standard gigabit network. If your method of backup fails for some reason any.

    But there are as many reasons for the failure of TM is not easy to understand.

    Use a work around if it is important to do this via the backup instead of direct.

    for example... a USB plug into the computer and use it as the target for backup... TM has done well above the local level as network drives.

    You can also create a clone bootable disk USB using Carbon Copy Cloner who is free to use for one month.

  • Time Machine won't recognise my backup disk.

    Time Machine on my iMac (2008) running El Cap 10.11.4 will not recognize the presence of my backup drive (a WD My Book Home Drive). Yesterday, I made a successful backup (the first in over a year).  Today, when I opened the time Machine he confirms DRANK yesterday in his status message, but says he can perform only the following when the drive is connected - although it is. I would be grateful for any suggestions or advice. Thank you

    How do you format this drive WD?

  • Time machine will not be finished

    Time Machine won't complete a backup of 900 GB on my mid-2012 Mac Book Pro with 8 GB of RAM and 1 TB of disk. the OS is 10.11.2. The external drive is USB - 3 5 to Seagate and there is nothing else on the disk.

    24-hour backup. For the last three hours, I've seen 35 minutes remaining; There seems to be no progress. What could be wrong?

    Run the Console application - it's in your Utilities folder. You can find it by selecting utilities in the Finder go menu.

    If the list of newspapers on the left column is not already displayed, view journal list by selecting view list of newspapers on display menu of the Console. Select Show toolbar if it is not already displayed.

    Locate system.log in the list, and then select it. Many date and time-stamped entries will appear, hundreds of them, and you need to find the relevant entries to your Mac problem.

    Do that type backupd in the field of filter of the Console.

    One or more of these log entries may reveal the reason for the problem you describe.

    Copy and Paste the log entries in a response. If hundreds of same repetitive messages appear, please change them before posting. There should be no need of several journal entries.

  • Backup problem: iMacG5.sparsebundle could not be accessed error null

    Hello

    I have an iMac G5, 27 "; Processor - 3.4 GHz Intel Core 17; Memory - 4 GB 1333 MHz DDR3; Software - OS X 10.9.5 (13F1808)

    Since yesterday, it was not able to Time Machine backup.

    The initial error was "iMac that G5.sparsebundle could not be found (error-1).

    I found a few tips here and there followed:-unplug TC; go to network/SystemPreferences, renew the DHCP lease

    Still did not work.

    Is passed to the next stage of advice:-open the TM preferences panel, remove the TC list of backup destinations, add in

    Still did not work.

    Error message has now changed to "iMac that G5.sparsebundle could not be found (error (null)).

    Is this a defective Time Capsule?  (This is the conclusion, in other similar post, I found that my error message ('null') is different from that of this post).

    Thanks for any advice,

  • iPhoto has lost all the additions from June 2015 to 21 Feb 1016. Tried to restore from Time Machine, it still has the gap.

    The date is February 24, 2016.

    I'm studying me ways to copy the library iPhoto in full on an external drive. I've been in the Finder > my username > photos, simply by looking at the dates, and I'm not aware that I made any changes.

    I was adding a handful of photos every day for the last week or two.

    I noticed that the file system is not quite as it was a week ago, and it seems that the last event is June 29, 2015, up to an import on February 22, 2016. In other words, it seems iPhoto has restored to its state of June 2015 then accepted imports from February 2016. I had not yet been in Time Machine!

    In the Finder > username > images, from now on, I see there: -.

    "Today."

    "iPhoto Library", type - package, with a white page icon folded, created may 2012, 30.8 GB, modified today, version 9.4.3.

    'iPhoto Library (original)', kind - iPhoto Library, with a colored icon, created may 2012, 27.46 GB, today, no modified version mentioned.

    «Past 7 days»

    "iPhoto Library (2 originals)" type - package, with a blank icon page folded, created may 2012, 30,77 GB, modified February 19, 2016 (its Feb 24 today), version 9.4.3

    In Time Machine, I restored version Feb 19, I find that the library was complete at this date, but the library has the same gap to date.

    I would be grateful for any suggestion. I didn't have it backed up to the cloud. Please have mercy, I'm not that tech-letter, so I would appreciate instructions step by step to the intermediate level.

    A big thank you Doug - greetings-

    You do not use the finder in any way with your iPHoto photos - when you launch iPhoto see you - especially in the last import, and last month "n"?

  • Why Time Machine will not erase old backups when it needs more space for a new backup?

    I have problems with Time Machine.  I am running on an iMac (21.5 inch, end 2012) with a processor Intel Core i7 3.1 GHz and 16 GB 1600 MHz DDR3 memory.  My OS is El Capitan, 10.11.3 version (15 d 21).

    Since a few days I received the following Time machine error message:

    Time Machine could not complete the backup "IoSafe.

    Backup disc neds 47,49 GB for backup, but only 39,98 GB are available.  Select a larger drive for backup or do

    the smaller by excluding the backup files.

    I thought that Time Machine was supposed to automatically delete older backups when there was not enough space on the backup drive.  Am I missing something?  Is that what I can do to diagnose the underlying problem?

  • Backup Restore Time Machine does not see RAID external drive

    Hi all

    I have a problem with my iMac restore from a Time Machine backup, and I was wondering if anyone else had the same problem already.

    I had to reinstall OS X El Capitan from scratch, based on education, I received Support from Apple. That worked without problems and my iMac works fine. However, I wanted to restore it to how it was before, using Time Machine. I keep my backups on a LaCie 5big Thunderbolt 2 and never had any problems with it.

    To restore the system, I followed the instructions on the Support page. I restarted my system in recovery mode and selected the "restore from Time Machine backup". Unfortunately the LaCie 5big does not appear on the list of drives, so I'm stuck... When you use the system in normal mode, the external RAID is visible and Time Machine stores backups on it without any problem.

    Any of you are familiar with this problem? I would be very grateful if you could help me with this problem!

    Kind regards

    Valerio

    Hello

    -While the system is booted in recovery mode, confirm that the Lacie 5big network is visible in disk utility.   You will need to disconnect / reconnect the Thunderbolt cable to the Lacie 5big be detected.

    -Once seen, a new attempt to restore from Time Machine backup.

    See you soon

  • Time Machine do not hourly backups on WD My Book for Mac new

    My 1 TB time capsule was too small for the full backup so I just bought a 6 new to WD "My Book for Mac" and have now a new back up, but it won't backup time as usual. I am running OS X El Capitan 10.11.6 Can anyone who thinks that the reason for what I fear not having a reliable backup. The problem with the new hard drive external or is - a problem with EL Capitan?

    Hello Arnaud,.

    Thank you for using communities of Apple Support. It is my understanding that Time Machine was not back up as expected. I certainly understand how it is important to be able to back up your content. I'm happy to help you.

    There are several factors that could influence the automatic backup. Please follow the steps in the link below to fix this problem:

    If you cannot back up or restore your Mac with Time Machine

    In addition to these measures, hourly backups could be affected by your sleep Macs and power Nap settings, depending on which Mac you use. To ensure that your hourly backups are finished, set your Mac sleep to a longer period time. For testing purposes, try to set the duration of sleep at least 1 hour. You can do this in system preferences > energy saver.

    In addition, if you use a portable Mac, make sure that it is connected to power during the tests to see if hourly backups work. See the link below to view information on how Power Nap works and how it can affect Time Machine.

    How Power Nap works on your Mac

    Keep in mind, that Time Machine backs up only files that have changed since the last backup.

    Have an amazing day!

  • Time Machine does not work after update of the Sierra

    The time function machine my Mackbook Air 2011 stopped working... it has not been saved since update for Sierra, it only take screenshots every hour, it will perform a backup is no longer on my external HD as before.

    There is no problem with the way it is implemented or the hard drive, it's me that my iMac is working perfectly since the update for Sierra and it's backup via the time machine on the same hard disk.

    It is a hard drive and put in place I was in use for about 5 years with no problems.

    Also since the update for Sierra I noticed that my MacBook Air gets hot and the fans go wild, although there was nothing or performance other than the system is auto.

    I lost the use of my built in camera after the update to El Capitan, and now I've lost the use of time machine... I was wondering if I should go back to Yosemite that everything worked well then!... is this possible?

    Thanks for any help with this!

    Update:-just so you know, time machine is to find the back up ok drive (external hard drive), it then goes to "preparing backup" and that's all, he remains in this preparation save the scene for centuries, after a while it just stops and it is saved all... nothing!

    Also noticed when I checked in Time Machine full backup I have before update for Sierra disappeared, he disappeared, been deleted... I don't know what is happening with it!

    Overall since the update for Sierra my MacBook Air did not work properly, in addition to all that Safari does not load, just to get the wheel spinning, and now (with the demise of my old back ups) it seems I can't go back to a previous state.

    My Mackbook Air took it!... the last update took the camera and really Sierra in... material not compatible with all new software, none of the new features work on my iMac or MacBook Air (only Siri), so a useless upgrade for me really, wish I didn't!
