MacBook backup

I wanted to backup my Mac with Time Machine and to store in a hard drive or a Flash drive, how can I check the amount of memory space do I need available in the disk storage for backup?

Select the drive in the Finder and choose read information in the menu file, or open a file on the issue, choose view bar status in the view menu, if necessary and look at the bottom of the window. It would take at least twice as much free space on the drive as the amount of data, you're going to be back up.

  • MacBook Pro 2012 sporadically slowdown since the upgrade: SSD ALL SSAY!

    Hello

    I recently updated from a Samsung 850 Evo 256 GB SSD to the 1 TB version. Everything worked perfectly on El Capitan before the upgrade.

    Since then, my Macbook (15-inch, mid-2012, 9.1) is very reliable. It has constantly been extremely hot, that fans speed up at bottom, unless they are overridden by third-party applications (fan SSD command), and even simple things like streaming video may cause the thing to grind to a halt. The battery life is also significantly more bad for exchanging the two SSDS.

    1. almost directly after installation of the SSD using my Time Machine (from the 256 GB SSD), underside of the Macbook backup was extremely hot to the touch and the fans were at full blast all the time. I have reset the SMC and downloaded SSD fan control to override the fans. This seemed to help for a few days, but then...

    2. on the accusation, it slows to a halt, which makes the Macbook unusable. I can't understand why, because it is not as if a particular application is the cause on several occasions. I noticed that kernel_task consuming CPU during one of these "slowdowns", so I tried the fix involving passing the model identifier of IOPluginPlatformFamily.kext after you turn off the csrutil of the recovery partition. But my model identifier was not yet which are listed there, there is nothing to move.

    3. the SSD seems to work very well. Repeated with BlackMagic Disk Speed Test assessment tests show reading and writing almost 500 MB/s.

    3. I ran the Apple hardware test and he told me that he had "no problems found".

    4. I have checked inside the case for excessive dust and has no problem.

    I scoured the internet to find answers and tried every possible solution I found, everything to nothing does not. Any help would be greatly appreciated - I am considering looking for a new laptop if I can't understand what is the problem, as I can't work

    A number of users have had problems with the new Samsung SSD.  Note that Samsung omits Mac compatibility on their web site.  Whether or not this SSD is the problem is unknown at this time.  You might consider to replace it with the prior SSD and see if there is a change.

    First of all, I suggest that reset you the SMC and NVRAM:

    Try a safe boot:

    If no change, remember to reinstall os x.

    Application of fan control do you use?  The reason why I ask, is that all of these applications I know, allow to increase the speed of the fan, does not decrease the speed.  To do this involves an element of risk because the conditions may require the speed high ventilation and by the user, reducing can result in thermal shutdown.

  • Mac Pro does not sleep

    Hello

    I noticed, that my Mac Pro (end 2013) with El Capitan is not going to sleep more, neither automatically nor manually by using the Menu.

    The screen goes black, but she is still ongoing. I tried the command "assertions of g - pmset" in the terminal, but there is nothing to prevent the Mac to sleep. Same thing with the activity in the Power Saver tab monitor. I also did a CMR and Reset the Pram.

    I think that the last backup may be the problem: I got a Macbook Pro, and I used the Macbook backup, to restore the Mac Pro.

    It's just a long shot, but I probably put the setting of night never inside the control panel of the Macbook, and this setting is not available on the Mac Pro.

    Which is causing the problem? Or does anyone know another solution?

    Thank you!

    My MP 2013 will also not sleep and I was not able to fix it without a new installation. If I can migrate users defining and app who won't sleep.  You will probably see journal entries that say, in output mode, low power, I.

  • iPad Mini storage problem

    On my iPad Mini, (first generation) under settings > general > storage & use iCloud > storage

    It shows that I used 11.7 GB and available 723 MB.  If I check the option of storage management, the

    total storage used by applications is total less than 1 GB.

    When I sync my iPad Mini with my Macbook (backup) synchronization page shows that the iPad has

    Used 738 MB and 11.3 GB available.  (which is more in line with the storage / app list).

    So why the difference between the used displayed rise up on the iPad and the actual amount of used storage?

    Making a full backup and closing, remains the "error".  Anyone have any ideas on how to solve this problem?

  • Delete the backups on my Macbook Pro

    I backed up my macbook with an external hard drive. I did it to free up space by deleting things out of my macbook and just to have them on my external hard drive. When I did it that he asked if I wanted to use Time Machine and I just agree, I don't know if Time Machine has nothing to do with the problem or not, but that's just what I know, it happened when the problem started to occur. After that my computer has been backed up and I deleted everything that needed to be removed I checked my disk space hard and instead to have plenty of everything I have just deleted, I now 28 GB used by backups. I tried to remove my time machine backups but nothing happened and I want to know how to delete these backups because I am in College and making movies and really need all the space I can get.

    Maybe that's the problem you encounter:

    https://support.Apple.com/en-us/HT204015

    If this is the case, you can ignore the shots as they will be deleted if more space is needed for other data.

  • Can I save/backup/restore my entire macbook system with iCloud?

    As above.

    I just bought PC World/Currys know-how, that is to say, their version of the cloud.  I don't like.

    Apparently, it allows that a restore if my macbook pops up, stolen etc.  iCloud should not cost much more.  I suspect iCloud would work better with my mac.  But, I can do as I ask above, IE, my mac restore everything from iCloud?

    Know-how is all just too confusing.  I can not even find were my photos are, and too many files have a big '?' by them.

    Thank you.

    No.... iCloud is no way to predict a backup everything on your Mac. This, to an external drive using the Time Machine application in your Applications folder.

  • I can restore a new Macbook Pro with a 128 MB flash usung a drive backup time Machine 1 TB?

    How can I use the 1 TB time machine backup restore the new MAC?

    Yes, but most likely you can not restore everything and will need to be selective about what should be restored because very probably a full restoration would take more than 100 GB and you need a free storage space so that you can not fill up the drive

  • How to set up backup Time Machine with MacBook?

    Hello community:

    I wonder what is the best way to configure a Time Machine backup with a new MacBook.

    Because the device has only a USB port that is also used to load, I don't really feel comfortable that I can only backup wile, the MacBook is on battery. That doesn't seem fair.

    One possibility would be to use the adapter USB C AV that she can continue to charge the MacBook while being a USB hard drive is connected. But I'm not a big fan of having to deal with three cards for a simple task like a backup.

    Apple promotes wireless with the MacBook. One possibility is to use a (rather expensive) Time Capsule or a NAS that takes care of Time Machine.

    There are now hard drives wireless market. Does anyone have experience with these?

    I'd be curious to know how you do it.

    Thank you!

    Ideal for keeping backups Time Machine 'behind the scenes', you want to use the solutions SIN or Time Capsule. You can also use a 802.11ac AirPort Extreme with a USB external HD as well.

    Don't forget the partial backups will occur at least once per hour after the first full backup is made to take full advantage of what offers Time Machine. Although the connection of an external disk directly to the MacBook would potentially offer the best performance of overall data transfer, it must be connected.

    Unfortunately, I have no experience with hard drives wireless so I can't help you there. Because they would have to connect to the same network of Wi - Fi as the MacBook, all backups would go first the wireless AP, then, on this disc. I can only imagine the performance of data transfer to be a little dismal at best.
