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 does not recognize the backups when you configure the external drive as a network drive

    I have a MyBook 5 to disk with a 1 TB partition that I used as a destination for Time Machine > 1 year now. I recently gathered the energy to connect the my book on my Airport Extreme Base Station (model 2014? the second model) to implement wireless backups. I plugged the MyBook on the base station, set up file sharing in AirPort Utility and created an account with access to the partition of TM on the MyBook under the section 'Sharing secured disk' utility.

    Now, when I open the time Machine, I choose this partition, but it does not seem to recognize that I have a string of backups already there. Then he tries to start a new backup. So a few questions.

    1. Should I abandon my old backups and start over? I don't think that I did nothing to my system in these last days that I would need to be careful, if I couldn't rely on a TM backup from that moment.
    2. Is there a way to get TM to recognize my old backups and start from there? I do not look down the barrel of a backup of time + 13.

    If 1, should I reformat the partition TM in order to start over? I don't see the older backups on disk when I look in the Finder, but I know that they are there and they are too much space. Help/suggestions appreciated!

  • New mac connects to the time capsule but does not see the old backups

    My new MacBook Pro connects perfectly to my Time Capsule, but it is not all backups that are there.  I can't scroll through them as I can with my old MacBook Pro.  The MacBook still connect to Time Capsule well and see and scroll through all the backups it.

    No idea why?

    I wish that my new mac to be able to go back through the backups as does my current MacBook.

    Thanks for any help.

    Since El Capo OS a lot stricter security.

    You will generally not be able to simply use a backup Time old Machine as you did in the past.

    Backups made by different computers must be used via migration assistant... not just opened in TM.

    However, you can always copy a file or folder, you must manually via the Finder... ride the sparsebundle and access... If you have issues copy folder in the form of TM and then paste it in Finder... There are different ways to trick the it.

  • Backup Restore Time Machine does not see RAID external drive

    Hi all

    I have a problem with my iMac restore from a Time Machine backup, and I was wondering if anyone else had the same problem already.

    I had to reinstall OS X El Capitan from scratch, based on education, I received Support from Apple. That worked without problems and my iMac works fine. However, I wanted to restore it to how it was before, using Time Machine. I keep my backups on a LaCie 5big Thunderbolt 2 and never had any problems with it.

    To restore the system, I followed the instructions on the Support page. I restarted my system in recovery mode and selected the "restore from Time Machine backup". Unfortunately the LaCie 5big does not appear on the list of drives, so I'm stuck... When you use the system in normal mode, the external RAID is visible and Time Machine stores backups on it without any problem.

    Any of you are familiar with this problem? I would be very grateful if you could help me with this problem!

    Kind regards

    Valerio

    Hello

    -While the system is booted in recovery mode, confirm that the Lacie 5big network is visible in disk utility.   You will need to disconnect / reconnect the Thunderbolt cable to the Lacie 5big be detected.

    -Once seen, a new attempt to restore from Time Machine backup.

  • 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.

  • 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.

  • 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.

  • Portege A600-138 with Vista 32 bit does not see the computers in the Group Win XP network

    Hello

    My Toshiba Portege A600-138 with Vista Business 32 does not see the computers in the workgroup.
    In our office, the computers are all equipped with Windows XP.

    When I connect my laptop to the Local network, I don't see any neighboring computers in Network Explorer.
    I spent 1 hour and 40 minutes to talk to a specialist Service of Support from Microsoft, and the only way to have access to local machines, we found it had to enter the IP of the computer directly into the computer browser path field.

    I hope you understand what I mean.

    The man said that he had no this problem with non - OEM Windows Vista versions.
    He meant that the problem was with the oem versions of Vista preinstalled on laptops only.
    He said that probably the sellers - in my particular case Toshiba - supplied their notebooks with VIsta oem images that were somehow corrupt.

    Does anyone have an idea of the cause of this problem?

    > The man said that he had no this problem with non - OEM Windows Vista versions.
    > It meant that the problem was with the oem versions of Vista preinstalled on laptops only.

    That's nonsense for me
    The Vista OS preinstalled Toshiba which is same BONE as full Vista disc from Microsoft.
    There is only one difference; Toshiba laptops are preinstalled with Toshiba and pilots tools and drivers and tools are part of the Toshiba recovery image that contains Vista, driver and tools

    You will find information that a problem has to do with the new Windows Vista network map.
    Windows Vista uses a new Protocol (Link Layer Topology Discovery).
    LLTD is integrated with Windows Vista, this is why they appear correctly in the network map.
    But the problem is that LLTD is not integrated with Windows XP, which is why they do not appear correctly.

    But you can fix the problem by downloading and installing the layer topology discovery responder.
    Install it and your PC Windows XP will appear on the network map.
