My book for Mac "preparing backup".

Hi all

I've updated to Sierra this morning and since then my WD My Book for Mac has been slain in the backup of the preparation for about 10 hours. My backup before the upgrade went through without a problem. Is the amount of time the backup takes to be expected with the upgrade or it's just stuck in limbo?

Thanks in advance.

Hello, Huss417!

Thank you for using communities Support from Apple. Congrats on the update to Mac OS Sierra! It's a great new operating system. From your post, I'm seeing that you have problems with your Time Machine backup since the update, even though - he was slain on "Preparing" for a lot longer than expected. I know the importance of these backups and want absolutely to make your passes by. I'd be happy to help you!

The following article will give you more information about what might happen.

Enjoy the new macOS Sierra!

  • 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!

  • My book for Mac 2015 becomes hot during the game.

    My MacBook 2015 becomes hot during the game. Is this a problem?

    Depends on heat, it gets. It is normal that some video games place a demand on the CPU and GPU, so you can keep track of the temperature. A good and free app for this is temperature monitor.

  • E3000 you see is not a WD MyBook for Mac 2 TB external hard drive

    Just bought a router from LinkSys e3000 and WD My Book for Mac (+ WD Smartware) in order to save my two MacBook Pro wireless.  The router works FINE for all other wireless and routing functions.

    Bottom line, the LinkSys Router cannot access external drive USB, the same scores if he can 'see' the reader. (By clicking 'claim' does nothing)

    This would have something to do with the functionality of ITS and drivers needed - since I can't add the drivers to the router.

    (1) valid router works by plugging an another WD MyBook essential 1 TB drive (PC version) and the routers sees several partitions.

    (2) worked with support technical LinkSys to check the router works with the journaled Mac partitions and the router worked as expected

    (3) added a FAT on my book Mac volume - still does not work with the router

    (4) plugged my book Mac directly on the MacBook Pro - works fine (actually a backup from two Mac Book Pro both 1 via USB direct connect)

    (5) off VCD - no luck on the router

    Can anyone provide a suggestion before I return this drive to WD?  I'm at my wits end.

    In addition, other that this problem with WD, I can highly recommend the LinkSys e3000.  Seriously HOT router with a huge flow.

    Yes... it's that I'm just understand! : smileymad:

    Please ask PD to put this future firmware support on the list for improvements.  I love the router, but really miss you a market of large target with this omission.

    It is closed for me.   Thank you!

  • 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.

    I suggest to run disk utility and see what it reports.

    This disk must be reformatted.

  • Reliable backup for Mac?

    Hi all

    I wish I had a solution for online backup for my mac, since I don't trust so that site comments more that increasingly are biased, I would rather ask my other consumers based on their experience!

    What are the reliable online backup solutions for Mac users out there?

    Features, I would love to find:

    -Backup crypted

    -Files/backups scanned and protect with antivirus and antimalware systems

    -Reliable in the sense that it is 200% of course, proven and protected that they will not share or disclose my data and they have secure servers

    -If possible, accessible from a Windows computer in case I need it

    I was thinking about everything that I wanted to put backup password protected DMG files (which are encrypted right?) and then upload to Google Drive, since at least Google servers should be online forever almost, but you are limited to 15 GB per account, anyone has any experience with the help of Google?

    Thank you!!

    The problem with online backup killer, is it will take perhaps as long as three days for any transfer out or or on your Mac. It is simply not practical.

  • Online backup solution for Mac files?

    I'm All in with the Apple ecosystem.  I have iCloud, which shows how to save my photos (most important).  But now, what of my files?  So far, I was backup on external hard drive using Time Machine.  But I prefer that my backup not to be on a device that could burn (or other) being sometimes advanced with my MacBook Pro.

    I know there are services such as Carbonite, but I would be everything-Apple if possible.  I know I can drag files on my iCloud drive, but this isn't a real backup solution.

    Any advice?  Thanks for any help.

    You must decide if you want to save your programs or just files - I personally backup files since all my programs can be downloaded or resettled

  • the backup of Microsoft Office for Mac to iCloud

    I can't save my documents from within Microsoft Office for Mac on my iMac in the iCloud?  Does anyone have a suggestion?    "HE."

    iCloud does not offer the ability to save a Mac computer. You can save an iPhone/iPad/iPod Touch to iCloud.

    If you have the Apple menu > System Preferences > iCloud > iCloud drive turned on, you should be able to save a document from the desktop to the folder of iCloud drive or drive movement documents previously saved to other folders to iCloud. You can go to Finder preferences > Sidebar (at the top of the preferences window) and put a checkmark in front of iCloud drive in this window that make it easier. Note that save or move the files to the folder of the iCloud drive will keep a copy on your local disk and synchronize in iCloud. It is not the same as having a backup because if you accidentally delete the local copy, the copy on iCloud is also deleted.
