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 stuck at "Preparing backup...". "for external drive

    Hello.  I recently upgraded to El Capitan of Lion - a terrible experience, but finally got it work.

    Anywho, today I tried to backup on Time Machine for the first time since the upgrade.  I left it at "Preparing backup...". "about four hours without change.  Then, I checked with the activity monitor essentially ~ 0 activity (< 1.0%="" cpu). ="" i="" then="" followed="" the="" instructions="" here:="">http://osxdaily.com/2014/03/31/time-machine-stuck-preparing-backup-mac-fix/, asking to delete the "inProgress" of the hard drive.)  I deleted the file from the Recycle Bin, restarted and still no luck.  I'm not sure of the "Spotlight indexing' - as I understand, I want to ensure is completed.  So I checked the status and progress is null and has been for over an hour.  (There are no blue in the status bar, just gray.)

    I then followed these instructions: problems of time machine of El Capitan by watching the Console application.  Here is an example of one of my tests:

    Uh, help?  Haha!  Thanks for reading.  Hope that someone has comments.  El Capitan has forced me to learn more about Mac than ever.  -My first upgrade!

    So, my guess is that your external drive is not happy.

  • 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.

  • Time machine does not see the existing backups

    When I tried to make a backup of TM to my doesn.t TM HD external see my existing backups and trying to do a new backup complete. Firstly, it said "preparing backup..." "that takes a long time before you go make a new backup full not not using the existing to make a differential.

    You're talking about two different things that above:

    • Create a new full backup
    • Recognizing the existence of previous backups

    You seem to be assuming that because Time Machine seems to be to create a new full backup, so should not recognize the existence of all the previous backups.  This assumption is wrong.  New full backups are created, for example, when the update of OS X.

    The way to check if the Time Machine recognizes the previous backups would be to use the Time Machine application to check if you can see previous versions of files.

  • Time Machine could not complete the backup

    Since installing a Superdrive replacement, Time Machine is not back up.  I get an error message that says: 'Time Machine could not complete the backup "Time Machine backup disk. Full backup impossible. An error occurred during the creation of the backup folder. »

    I followed the instructions in the Time Machine error - backup failed, but none of the steps solved my problem.

    I suggest that visit you Time Machine FAQ of Pondini helps with Time Machine. It is a vast site with almost everything that you need for using Time Machine. You will not find a better resource for Time Machine in one place. Due to the disappearance of James Pondini is the site is no longer updated. Therefore, some information may be somewhat outdated.

  • 'No available backup disk', Time Machine is not more Time Capsule

    I have a time Capsule 2 TB and it has been used by Time Machine for many months.

    A few days ago the Capsule detached from his power and today is now connected to the new.

    Time Machine reports the error "backup disc not available."

    Time Capsule lights are green, AirPort Utility is showing this device being lit also.

    Time Machine knows how much space is available on this unit. However, it is not able to use this device to register older backups or to create a new.

    I don't see this device in the Finder, although I couldn't see him there when everything is working well.

    Airport utility indicates an IP address for this device and I can ping.

    What to do now? Isn't it at least possible to mount to access the files on it?

  • 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).

    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?

    To turn off some appliances, you actually pull the plug on the appliance.

    Turn off all devices on your network, computers, routers, modem, printers, mobile devices, etc... in any order you want

    Wait a minute

    Turn on the modem and let it run for 2-3 minutes by itself

    Switch on the device connected to a modem and let run for a minute

    Keep turn on devices one at a time about a minute apart, until the entire network is back

    • Not mounted 'External 1' and threw it in a box that I keep for hardware failures
    • Renamed 'New external 1' on «external 1"»
    • Time Machine running and went to preferences. In the list of things to exclude the back - ups has been 'External 1.'
    • Removed '1 external' in the list of exclusions (highlighted his name and press the sign less)
    • Checked and found that "external 1" was still on the list of things to exclude
    • Repeated several times, but I couldn't go down the list

    What can I do to get the time Machine no no keep 'External 1' permanently on its exclusion list and the addresses as the same drive as the one I replaced?

    Furthermore, if I rename "External 1" to "New external 1", Time Machine will save it. But I can not just keep the "new external 1" name for reasons of scripts, etc..

  • Time machine does not take into account my partition which is case-sensitive.  Recovery has no data of this partition.

    I have a partition on my drive that is formatted for OS X Journaled, case sensitivity.  When I perform a backup, then recovery, all data in this partition is missing.  Time Machine does not recognize partitions of case-sensitive?  Strange, as the default format for Time Capsule itself is case sensitive.

    You cannot use the formatting case-sensitive with OS X. You will need to repartition the drive to Insensitive in full. You can not do any repairs or restore from a backup Time Machine.

  • After upgrade to El Capitan Time Machine does not automatically

    Recently, I upgraded my Macbook Pro and iMac 24 to El Capitan.  Time Machine does not automatically work on the iMac.   I now use the backup to get a backup to run.  MacBook Pro is very well.

    Thinking that this might be the associated time Capsule, I removed the disc from the Capsule and ran Spinrite on it.  Car is very good.  Then I deleted all the files on the Time Capsule and created new Time machine backups on two computers.  No problem, except the iMac not run automatically Time machine.

    And yes the selection for Time Machine is configured to run automatically.

    A bug in OS X 10.11.1 prevents automatic backups that happens when a desktop Mac (iMac, Mac mini or Mac Pro) is connected to a UPS (UPS) with the USB feature.

    Please, back up all data before proceeding.

    First, check the App Store for a later update to OS X. If it is available when you read this review, install it and see if the problem is resolved. I speak not beta versions.

    Otherwise, you can work around the bug as follows.

    These must be run as administrator. If you have only one user account, you are the administrator.

    Please triple - click anywhere in the line below on this page to select:

    sudo defaults write /Library/Preferences/com.apple.TimeMachine RequiresACPower 0

    Copy the selected text in the Clipboard by pressing Control-C key combination.

    Launch the Terminal application integrated in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    Paste in the Terminal window by pressing the command-V key combination. I tested these instructions only with the Safari browser. If you use another browser, you may need to press the return key after pasting. You will be asked for your login password. Nothing displayed when you type. Type carefully, and then press return. If you do not have a password, you will need to configure one before you can run the command. You can get a warning to be careful. Confirm. You don't need to display the warning.

    If you see a message that your user name "is not in the sudoers file", then you have not logged as an administrator. Log in as one and start over.

    Wait for a new line ending with a dollar sign ($) below what you entered. You can then quit Terminal.

    Restart the computer and test.
