• 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.

• Mac OSx Sierra Time Machine WD my cloud

  Since upgrading to Mac OSX Sierra my Macbook Pro and Macbook Air are not capable of doing Time Machine back Ups to a WD MyCloud drive that is connected to our router.

  We have updated the firmware on the WD My Cloud drive to the latest version and contacted WD on this problem, so far they have not come with a solution to the problem.

  If you open Time Machine preferences and then observe what happens, by hitting 'Back Up Now' systems do "Looking to save the disc" then "Preparing backup" then stop and then go back to the status of 'rest' without backup anything to the top at all. It is the same on both machines. You can see here: Time Machine Back Up My Cloud

  Notice how the drive icon changes to the point where it stops working and then goes to the other drive which is a USB.

  Now, to complicate the issue further... an iMac connected via Ethernet to the router can go back to the My Cloud drive perfectly as before. If Apple changed something with the wireless protocols I think but that?

• Sierra Time Machine / Time Capsule problem

  After installation of Sierra, I am unable to use Time Machine to a Time Capsule.

  There was a MacBook Air with two bootable partitions. The partition Macintosh HD has a system of Yosemite and the score of 'second' was a partition of El Capitan, which was created by a clean install and then allow Migration Wizard copy on Macintosh HD, all accounts, settings, networks and other files. The two partitions have been saved by Time Machine to a Time Capsule. The Macintosh HD partition has been erased and Sierra has been installed on Macintosh HD and Migration Wizard was allowed to copy during the second all accounts, settings, networks, and other files.

  Time machine has not worked since. It gets the error message 'no available backup drive.' However, using the Finder, I can get the time Capsule, open the sparsebundle and see all the individual backups. Because I had erased Macintosh HD, I went through the steps to http://pondini.org/TM/B6.html 'reconnect to my backups. Which made no difference (probably because Time Machine is not really see her driving the sparsebundle to the Time Capsule, even if the Finder does no harm to open it).

  Then I tried to select again the Capsule as the backup drive. It asks for a password. I give the password and shortly after it comes up with the error message: 25299 Keychain error when creating a system keychain to the URL entry and the user name '< name >' "afp: / / < name > @2%20Tb%20Time%20Capsule._afpovertcp._tcp.local./Data.

  (where < name > is the name of the logged-in user) I get the same error message if the user is an independent Director. Despite saying that it was not able to create an entry in the system Keychain, Keychain Access shows that there is an entry with the password. In addition, despite being unable to choose as the backup drive time Capsule, he mounted and left on the desk, the time Capsule (containing the sparsebundle) data folder.

  Any suggestions?

  You are the second today with errors of Keychain.

  Time machine on network not connection

  Sierra is a new OS will have a few bugs... but I think that the way you did this configuration is problematic.

  Actually, you have now two partitions with different BONES, but they will have identical computer names (migration has more the name). And it could also spoil the UUID of the disc.

  I guess, but I would say

  1. change the name of the computer.

  2. start a new backup... do not try and link the existing backup.

  3. If you still have no success Delete TM (A4 Pondini) plist and reconfigure.

  No post luck returns.

• Sierra &amp; Time Machine in Mac OS problem

  Since the upgrade to Mac OS Sierra I can't backup using Time Machine to an external hard drive. The backup took three hours for 5 MB of data backup! Out on the kind of Apple it if you please. Anyone know the answer?

  Do you have an antivirus running? If so, try tuning it out.

• Sierra Mac OS and Time Machine?

  Hello

  Since the update for Sierra, time machine takes really long in the "preparation of backup." I was not able to save my mac since. Can someone tell me why this is happening and if I'll ever back on my mac?

  The first backup after that an upgrade of the OS can take a long time, leading people to think something is wrong. Sometimes, something is wrong - maybe it's a coincidence, but I think it's during these periods of preparation time that a TM backup is more likely to stall. So the first thing to try is defined the computer don't not sleep and manually start a backup of the day after. If this good return. If this is not the case, the second thing (if you can't wait go to this step) is to open the TimeMachine backup and open the backup.backup folder and the folder of the computer to find the actual backups. You should see a file called 'ongoing' remove it. (I open open TM preferences and turn off TM before doing this.)

• Time machine no longer works after update to Mac OS Sierra

  Backup Time Machine has stoped working on two of our Macs, I've updated for Sierra (MacBook Pro 15 "beginning 2013 and iMac early 2016"). They don't backup but are blocked for days now in the 'backup preparation' (connected via gigabit ethernet). The iMac uses our backup NAS (Synology DS216j) and a USB HD (Maxtor), now it can't mount the USB HD or, as the MacBook Pro, get to the point of actually perform a backup on the NAS backup server. All computers (all six of'em, five Mac and a Windows thing) was perfectly support towards the top, but those updated for Sierra no longer.

  Someone else who has had this experience and even has a clue what to do about it?

• Time machine backup is too large, that is not true, said

  After the upgrade to OS Sierra, Time Machine always tells me that the backup is too big to fit on the external drive that I use. I erased the disc and checked all volumes, I don't want to back up. He always tells me that the backup is 2 TB.

  My boot drive has 155 GB in use, I do not understand why TM attempts to use 2 TB. I've removed the preferences, he always tells me that it is too big. The external drive has 1 TB of free space.

  Any suggestions?

  If you open Applications > utilities > Terminal and paste the following command and press return, what is the result:

• I've never done a Time Machine backup and I have upgraded to iOS Sierra. Help!

  I'm a fool. After owning my Macbook for 5 years, I failed to make a single Time Machine backup. I just saved my essential to an external hard drive. I have upgraded to iOS Sierra. Big mistake. I want to go back to iOS Capitan, but it does not seem possible. Now, my external hard drive is wiped clean (things are dark). What are my options? If I'm stuck with Sierra?

  If you have downloaded El Capitan, it should always be available in your purchases. Now, you will need to make a backup to backup your personal files.

• Time Machine does not work after upgrade to Sierra

  The Time Machine (TM) fail to start backup and there is still "preparing backup...". "for more than an hour. This right after upgrading to Mac OS Sierra.

  Another weird thing happens to the toolbar of the Mac Mail. The Junk button is replaced by another button. trying to put back in place, but remove the button become a button.

  Please help with the backup problem mentioned above. Thank you much in advance.

  How long have you waited? After a new installation, it must be a fair while even with a SSD to prepare the first backup due to the number of modified files.

  Make sure the TM drive is in the list of items excluded from Spotlight indexing. ICloud newsletter and other cloud services.

• I am on a MacBook Pro mid 2012, Yeosmite 10.10.5, I want to switch to Sierra and am nervous to do when I had a terrible experience upgrade to Yosemite.  I have everything backed up on Time Machine. Can you please advise me?

  I am on a MacBook Pro mid 2012, Yeosmite 10.10.5, I want to switch to Sierra and am nervous to do when I had a terrible experience upgrade to Yosemite, support with gratitude by Apple in charge.  I have everything backed up on Time Machine. Are there steps of preparation I need to do before you download and upgrade to Sierra.  Can you please advise me please?

  N ° so you have a backup if something goes wrong you can return to Yosemite.

  Only concern is that some devices, including USB that may require the updated drivers, but these records are not always available

• Time Machine is not backup as I loaded Sierra

  My time Machine says that it has not saved for 890days? Since I loaded Sierra now its in "preparing backup" permanent mode

  Reboot, try again.

• Time Machine or backup from Sierra installed

  I backup my MacBook Pro and MacBook Air to Time Machine but show just 'preparation' constantly.  Tried rebooting the Machine and the time of the Macbook, and they are all connected via Airport utility.  Don't know what other troubleshooting I could undertake?  Any help gratefully received.

  Sierra is having issues and never use Time machine on top of an existing backup anyway.

  The steps are to.

  1. archiving of current backups.

  Plug a USB key that is equal to the size of the disk of the CT (you mix the terms Time Machine... software backup on the computer... and Time Capsule... material target for backups within a router).

  Archive is on the airport utility disk tab.

  

  2. once the backup is complete. It may take a day or two for 2 TB which is full drive.

  Erase the disc from TC... a quick erase is fine.

  It takes only a few minutes.

  3 factory reset the TC and reconfigure airport under Sierra on one of your Mac utility.

  Reset Time Machine preferences and it should start and run very well.

  But also, you should read some of the other threads here on the problem.

  For example... preparation is supposed to spend a lot of time when you try to use the existing backup... more wireless with two computers together... It will take days to complete.

  Open the activity monitor and ensure that other processes do not always use CPU. A person discovered photos was chew 90% CPU making a function which is part of the update and not allowing any time for TM backup in progress.

• Time Machine backup after the installation of the Sierra

  I installed Sierra, which lasted 1 hour and went well. Everything was in place. I did a clean install with El Capitan, so I've updated with Sierra. I connected external drive, kept saying PREPARATION BACKUP, but she never did.  Just stuck.

  Does anyone else have this problem?

  Resolution?

  It is normal for a backup after an upgrade of the operating system to take some time.
