macOS Sierra stuck on the Time Machine backup

Its been 2 weeks now since I updated to macOS Sierra and my Time Machine backup is always stuck on "preparing backup" and I tried different disc backup on another partition but still no luck.

Make sure that:

o drive the TM is excluded from Spotlight indexing non-mandatory;

o that all software anti-virus is disabled (especially Sophos);

o journal of iCloud and other cloud services.

    It is not an option for the HFS + and so I used; OS x EXTENDED (journaled). GUID is ok.

    Can someone let me know what I need to do.

    Thank you

    Formatting: GUID Partition Table, OS X Extended (journaled).    (it is HFS +)

    For TimeMachine at best to a partition only.

    Do it again if necessary, then disconnect, reconnect, Start Time Machine preferences and "select disk".

  • What exactly does the Time Machine backup?

    What exactly does the Time Machine backup?

    We have a Mac Pro towers (NOT for sale) and Mac mini with several hard drives installed internally.   Time Machine backup all internal disks or just the boot disk?   This can be configured?

    Time Machine backs up your default boot partition. However, if you have more than one drive or partition on your Mac (and it is formatted in "Mac OS extended (journaled)"), you can set the Time Machine to save these drives too. You can do this by removing these drives from the list of excluded items in System-> Time Machine-> Options... Preferences, so that the next backup will include all internal hard drives or partitions that you want to back up too.

  • Door key lost in the time machine backup

    Dear community,

    Because I had trouble with the speed of my MacBook Pro (and nothing else developed), I had to set up entirely new.

    Before installing El Capitan, my MacBook Pro (starting 2011) ran on Yosemite 10.10.5. I made two backups with time machine, generated a bootable El Capitan installation USB key, in format Macintosh HD, installed at El Capitan and ran all the updates. The system works well, everything works perfectly and my Mac is fast again. Now, I manually copy things that I need in my system of charges.

    Here, the problem is: I can't find the old keychain file in the time machine backup!

    Keychain works with the keys stored in iCloud. However, the other buttons are gone.

    As I discovered, ~/Library/Keychains is hidden. I did it visible on my system running. However, this does not work in the backup file. It remains hidden or - worse - have not been stored in the backup. I don't know that I have excluded from time machine backup only two totally different folders (dropbox and movies).

    You have any ideas how I can find my keychain (login.keychain if my search was right) in the time machine backup?

    Thanks a lot for your help!

    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.

    If you need to restore from a backup of the hidden user library folder, first select a snapshot, and then press shift-command-G. A go to the folder dialog box opens. In this document, you enter the path to the folder. The dialog box will help you by automatically filling parts of the path when you start typing.

    The path starts with the slash character ("/"). Enter that. The rest of the parts is separated by slashes.

    The next part is the date and time of the current snapshot. Enter a '2', and the rest of the date should be filled in automatically. Press the right arrow key to access the end of the path. Enter a slash to start the next game.

    Next is the volume name (usually "Macintosh HD" unless you assigned a different name.) Start typing, then jump to the end and enter a slash.

    The next part is 'Users', followed by a slash.

    Then is your short user name. It is also the name of your home folder, which is represented by an icon of the House in the sidebar of a Finder window.

    Finally, enter "Library", and then press return. You should now be in the library folder. From there, you can move like in the Finder. You can also select another snapshot of the same folder.

  • I can't remove the time machine backups, I put it in the trash

    My backup disk is almost full, and I want to take on a value of years of backup files until I can get a new backup drive to perform other files that I want to keep. I tried their erasure of the finder inside the time machine, but nothing happened. I sent them to the trash, and they seem to have disappeared from my external backup drive, but are now stuck in the trash. I left the machine running all night to see that it says it cannot remove these files because they are locked. Can you please tell me what I should do now?

    Thank you

    Hello Suzanne,.

    Go to the trash and use "Put" place files back where they belong. Time Machine is designed to remove automatically the old backup when it is full.

  • Cannot delete the Time Machine backups

    I have a MacBook Air and a 128 GB USB key that holds my library of photos, so I always make backups. My system - and I have recently made account how flawed it was - was to create backups on a 500 GB HARD drive, but to transfer them to a 2 TB HARD drive when it is full. So, I finally discovered that when I transfer backups in small quantities to the 2 TB, it takes more space because instead of aliases of files used to represent more recent backups, care of file just copied over and over again. For this reason, I put my 2 TB as a feature of time machine and imported all the old backups in the folder backups.db, that my Mac 'cleaned' and registered 135 GB. But 135 GB is not enough, I went and delete backups that I don't have anymore. When I looked in the trash to empty, I've seen 2 things: backups I have trashed and others who are pale sort out. I can't open the files, even if I right click and select "open in a new tab. When I try to "immediately remove" these paled-out files, I always get a message that they are "on duty." It is about 300 GB, so I must get rid of him. But it does not stop there, because when I try to "delete immediately" backups I had trashed myself, I get an error message! It is a total of about 600 GB, what I absolutely need to get rid of! If anyone has some tips, it will be greatly appeciated.

    You have probably sprayed your Time Machine backup database. The best thing to do is erase the disc with Airport utility. Then start again with a new backup.

    Good day.

  • Remove the Time Machine backups in a certain amount of time

    I have an iMac in the House which is not backup because I have just updated to El Capitan, then now it says that the time Machine doesn't have enough space for a new backup (no doubt because my 200 + GB photo library moved to the new application Photos). Therefore, I need to get rid of some my time Machine backup. My MacBook Pro has almost 1 TB of backup files and I want to delete some, but I don't want to delete ALL my files backup, just in case I need something from him. Is it possible to delete the backups in a certain interval of time quickly, in order to keep all my backups and delete the 'old'? I know that you can delete the backups one by one, but the first backup of my MacBook was in 2014, and I don't want to have to go through 100 backups one by one to manually remove all the...

  • You can use migration assistant to transfer the time machine backup external hard drive?

    Hello. I just bought a new macbook pro with a 256 GB flash drive to replace my previous macbook pro that had a breakdown of all the systems. My problem is that I have a time machine backup that is greater than 256 GB (it's almost 450 GB) and I try to find out if I can use migration assistant to transfer all the content directly on an external hard drive, then move the content I want on my hard drive from the external hard drive? My goal is to let my music and photos on the external hard drive and for all port hardware I need for work.

    I don't have access to another mac with storage well enough that I have the old HD so could potentially be installed in an external enclosure and extracted files directly from there if it's easier.

    What I intend to do in the long term is to buy a big external hard drive network and put all my photos, music etc over there and use the laptop as expected - that is for files from day to day - then it will be just a short-term problem.

    Any advice would be really appreciated.

    Thank you

    Nick

    Migration Assistant is user to transfer data from one computer to the other.  If I read your post correctly, you want to copy your data from Time Machine on another HARD disk.  Thia may be useful:

  • error - 36 on Time Machine backup

    Help! I went on vacation for a week of my iMac running that yosemite was working fine when I left him. I left it turned on on my back, he had frozen, and disk utility showed that the player needed repair but it was irreparable. So I started from a system disk and deleted from my drive, hoping to restore from my Time Machine backup which was connected all the time. (I also have a Clone of Carbon Copy backup). But the Time machine backup restores, showing me "error-36". I'm quite familiar with the operations of Terminal "dot_clean", but when I try it tells me that the command is unknown. And, of course, the problem is with the Time Machine backup, not with my hard drive. is it possible to repair the Time Machine backup in my situation? I can't restore my backup CCC because my iMac can't see, had no installed system. I'm about to try to completely install the original Snow Leopard system from the boot disk and then either try to restore from time Machine, or migrate it again.

    Can anyone offer advice please?

  • How can I migrate a time machine backup external USB drive to time capsule

    Searched the forums and can't seem to find an answer. With the help of El Capitan 10.11.6. You want to transfer backups Time Machine 4 years on an external USB drive on my new Time Capsule. Any ideas would be MUCH appreciated.

    There is no official method because it has problems.

    There's no official way.

    Here see Q18. http://pondini.org/TM/FAQ.html

    We recommend that people not me there. It has not proven reliable long-term. Start a new backup on the TC and keep the USB stick in the form of archive. After a few months or a year you won't have it.

    You have to understand the Time Machine backup otherwise locally the CF network. It is easy enough to move the backup network local but much harder the other way around.

  • Time machine backup missing messages?

    I recently did a clean install on my MacBook Pro. I don't want my my time Machine user account migrate upward, but I would like to transfer my text messages. I know that messages are located in the user/library/messages/archive folder that I can find on my Mac, but there is no such folder on the Time Machine backup?

    What Miss me?

    Hello

    I would be accessing ~/Library/Containers/com.apple.iChat/Data/Library/Messages/Archive on my computer because that's where my Archive is.

    See the path bar across the bottom.

    I know some posters have said there is here an Alias that is connected to ~Library/Messages/Archive as you describe.

    If you have two different locations through the current startup and time Machine, you might need to manually open the backup file and then drag the content to where you want to or need them to be.

  • Clone of Time machine backup to a new drive?

    I'm trying to help out a new Mac. Before, I had two back ups of all my data: on the hard drive of my old iMac and my external time machine backup disk. Long story, but during the process of troubleshooting using AppleCare support, my iMac has been cleared. Now, I have only the Time Machine external backup.

    I bought a new drive for Time Machine external backup on my new Mac. I am very very afraid of something bad happens to my old Time Machine backup during the troubleshooting process. My question is, is there a way to clone back to the top of my old drive time machine to the new, so I once more two copies?  If something happens to my old time machine up during this process of troubleshooting, I won't lose all my files.

    I'm not familiar with the Time Machine backups, and even if they need to be cloned since that they are not bootable backups.  The following link is dated but maybe having the relevant documents:

  • Why my Time Machine backups do not take many hours?

    I recently changed my external backup of a disk in a big flash drive backup.  Some of the Time Machine backups take several hours, sometimes all night or more.  General info on Time Machine Prefs will show large backups, as now "backup 39.6 89.7 MB, with a remaining time" (the flash drive is only about a quarter of full.)  Is it normal for a backup of the USB?  Thank you.

    How the drive is formatted? It should be in Mac OS Extended journaled.

    This is my first backup. I am 10.10.5 running on my mac pro book. Sound was support for 19 hours. Now, I have a notification on my office indicating the time machine backup, but TM system preferences menu States it is still encrypted. Am I done? Backups check is grayed out.

    If you chose to encrypt the backup, simply let him finish. Once this is complete, Time Machine should resume normal backups.
