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.

  • Backup Time Machine greyed out, even if the external drive is attached and backup is present

    Try to restore an old iTunes library and all my music for complex reasons (two on a Macbook Pro hard drive failure, not enough space for iTunes on the SSD space have now). I have a Time Machine backup to an external drive that is plugged, and the backup I need is clearly visible in the Finder. But in Time Machine, it is grayed out and inaccessible. If I try to just copy the iTunes folder, overall I get an error "not enough free space" even if there is lots of space available (119 GB iTunes folder, 165Gb disk space). Any ideas gratefully received.

    System information:

    Proof that I'm not a fool:

    Time Machine, please press the shift-command-C key combination. The windshield will show the mounted volumes. All snapshots should now be accessible. Select the one you want and search for files to restore.

  • Time Machine - an exclusion different backup for the backup drives different time machine

    I hope someone can help me.

    For these past years, I used 2 Time Machine backups to keep all safe. I have 1 backup x who lives at home and is 3 times the size of my disk. I also have a second drive of laptop that I travel with, which is partitioned to give a little time machine backup, more than 1.5 TB of "overflow storage (for movies, video files, etc).

    Recently however, I realized that my "storage of listening" actually contains a large amount of data I wouldn't lose (especially the photos of my children because they were born), so now I want to save this drive as well.

    If my ideal situation is to have a huge drive I leave at home. This contains backups of the computer AND 'excess of storage' backup. It's pretty simple to implement.

    But can someone tell me if my trip backup, will try also to the other partition of the backup drive? And if so, is there anyway to give different time machine backups different exclusions.

    Hope that makes sense and hope that someone can help me.

    Thank you
    John

    You will need to manually change the exclusions when you going on a trip. There isn't a way to change automatically.

  • Can I partition my drive Time Machine to back up the other 2 drives?

    Is it possible to partition a hard drive and use it with Time Machine to back up the other 2 drives?

    Example: I want to save internal drive of my iMac and my external storage drive, and I wonder if I can partition a hard drive for use with Time Machine, in order to safeguard my internal drive on one partition and the external drive to another partition. Hope that makes sense.

    Yes, if it's not a time Capsule, but I wouldn't recommend it. I would use readers separated for each device you want to back up. If you put all one hard drive and this player goes down, then you have lost all your backups. With separate if backup fails a drive you will always have backups remaining intact.

  • MacOS Sierra - time machine stuck preparation backup on network devices

    Since I've upgraded to Mac OS Sierra, cannot use my local backup USB. Time Machine is stuck with the message "preparing backup" - more than 12 hours - for network devices, an Apple FileVault and another NAS device. Works very well with the local USB drive.

    Something funny underway with network devices such that she works for the drives the.

    Hope Apple take note and fix.

    I have the same problem. I found this,

    macOS, problems of the Sierra: Time Machine backup Mac

    Time Machine problems prevented the Mac owners of their devices to backup since the upgrade to Mac OS Sierra, and the problem is widespread enough that Apple has published a guide on what to do if you can't back up:

    Discount for the iMac SMC

    1. turn off the device

    2. unplug the power cord from the monitor

    3. wait 60 seconds

    4 reconnect the power cord

    5. DON'T TURN ON DEVICE

    Reset the PRAM

    1. the computer must always be switched off.

    2. Locate the following keys on the keyboard: command, Option, P, and r. you need to hold these keys down simultaneously in step 4.

    3. press and release the power button to turn on the computer.

    4. press and hold the Command-Option-P-R keys. You have to press these keys before the gray screen appears. Continue to hold the keys down until the computer is restarted, and you hear the tone of starting for the 3rd time.

    5. release the keys.

    You can then try to save again. If this does not work, try to disable indexing on the drive you want to back up.

    but I'm not sure it's the same question. I'll try it and report.

  • I could install a copy of Windows (via Boot Camp) on my external drive for Time Machine without erasing my backups?

    I want to use Windows 10 (for games) on my 2013 MacBook Air (13 ", 128GB flash, 1.3 GHz Intel i5, 4 GB of RAM), but I want to install it on my external hard drive because I am almost out of space SSD (34 GB remaining), and I know how large windows is. I have an external 1 TB harddrive that I use for my backups Time Machine, and I was wondering if I could transfer my copy of Windows hard disk external and implemented via Boot Camp.

    Lol as the second partition on the boot volume. None of the other partitions will be allowed thereafter.

  • 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 external hard drive (Time Machine) has not been saved for a month.

    A month ago I left town for a week. After coming back, I noticed my icon time machine backup constantly Menu bar, but I paid no attention until three days when he tried to save in vain, I noticed. I tried to disconnect and reconnect my external hard drive, but it still does not work. Nothing has really changed any other times where I was out of town and time machines worked perfectly well. The only thought I have, which could prevent the machine from time to work, is that I've been reluctant to do the software update. I heard terrible things about the captain, especially when it comes to iPhoto, and iPhoto is my main thing on my computer... so I had voluntarily decided to not update. Do you think that this is what is causing the problem? Thank you very much.

    You him have not said if you did all troubleshooting. Tell us what troubleshooting have you tried, and then we can give you an idea.

    Furthermore, El Capitan is very stable. However, you should not pass until your system is stable.

  • Time Machine backup to external drive connected to the TimeCapsule

    I have a 3 TB TimeCapsule, that contains the my iMac TimeMachine backup. So far so good.

    Now, I would like to connect an external drive to the TimeCapsule via the USB port to allow access to this drive of my iMac as well as other computers on my network. I would like to than the external to include in my Time Machine backup drive. Is it possible - by accepting that the backup of obviously only runs when the Mac is on? If this isn't the case, other methods of backup to an external drive, connected to the TimeCapsule, may be recommended?

    You can do it. Time Machine it will support up to a separate folder on your backup disk. Don't forget to remove it from the exclusions list in Time Machine preferences. I don't know if others cannot see the drive connected to your computer is turned off. They may be able to mount the drive on their computer as you do on yours. Try it because I could be wrong on this matter.

  • Time Machine 'clean up older backups' takes too long

    I see that Time machine for my iMac does daily backups. Recently, he completed a backup in an hour or two. Then it does «clean up older backups...» ». Unexpectedly, it takes a lot of time, up to 6 hours. Sometimes, I need to close and stop without completing the cleaning.

    Syslog says:

    05/07/16 9:32:35.518 AM com.apple.backupd [207]: deleted the backup of the Volumes/time Machine Backups/Backups.backupdb/dk/2016-03-07-072332 containing 6.51 GB; Now available, 251.2 GB 529,85 GB required

    When I run the diagnostic tool EtreCheck, he said:

    Total number of backups: 25

    An older backup: 02/08/16, 08:50

    Backup disk size: too small

    997,71 GB backup size < (disc 664,27 GB X 3)

    The questions of the community are:

    Why cleaning taking so long?

    and

    If she tries to delete older backups can just go in there (/ Volumes/Time Machine Backups/Backups.backupdb/) myself to remove older archives?

    NO, stay away from the database of Time Machine. Cleaning of files may take a while, but you don't have to wait until it finishes. Just stop your Mac when you want, she can continue to clean later.

  • Can I use Time Machine to back up to an external hard drive

    iMac mid 2011

    OS X 10.11.5

    I use Time Machine - have for a long time.  It backs up my internal hard drive on a joint external Western Digital 2 TB of hard disk, as usual.

    Can I also add that another attached an external hard drive (where I have videos and photos stored) and saved it on the first external hard drive also?

  • is it better to restore from time machine or from a backup cloned

    I just got my replaced Mac hard drive. Of course, I did a backup first - two, in fact. One is my Time Machine stored on my Time Capsule backup. The other is a backup cloned, made with SuperDuper!, stored on an external hard drive.

    Now, the mac is back with it's all new hard drive, and I was wondering: is there an advantage to restoring from a backup vs the other? Is "Restore from Time Machine backup" a better option than with SuperDuper! to restore the clone bootable? Or vice versa? Or does really make any difference at all?

    Additional info: the TM and Clone were both looking at the same time (give or take a few minutes) and the Mac, at the time where it has been saved, ran the Mavericks. I also asked Apple to install the Mavericks on the new hard drive instead of El Capitan.

    Display?

    Thanks in advance.

    It really makes no difference that you are restoring from.
