Why is Time Machine backup 2 times every hour?

Time Machine backup to 24 times per day. Backups seem to be monitored hourly backup of 2-5 minutes later.

Yes, it is possible. After hours of that backup Time Machine check if changes have been made during the backup. This can cause an additional round of backup (usually short).

  • Why my Time Machine backups are sometimes surprisingly high?

    I've got Time Machine on a hard drive external and everything seems to work fine, but every day the backup is surprisingly wide - as in, 30-50 GB or more. I'm certainly not do anything that would lead to these major changes - no video editing or anything like that. Time Machine is set to the default backups every hour. What also confuses me, is that I've got Time Machine will a player all the time (well well, every hour) and also an extra drive I plug in every day or two. 'All the time' by car has just been a 30 GB backup an hour - and now I plugged the drive "every day or two", and that's just make a backup of 1.4 GB, even if it has not been saved since yesterday. Why is this happening? It's sort of expected behavior? Why a player thought he had to be updated with 30 GB, and the other drive think it only needs to be updated to the same situation with 1.4 GB?

    Speculation: would be updated to it somehow in my library of Evernote? (Which is about 30 GB). As far as I know Evernote is not supposed to change a lot, but maybe the changes I'm making some notes are somehow make a brand-new 'package '. Or, would she be Plex-related? My video library for Plex is on a separate hard drive, but is there some kind of another image for this on my main computer? I have no idea if either of these possibilities in any sense, but these are only guesses than i've got, and I only started to use Plex a month ago - which is at the same time, this problem appeared.

    Thanks in advance!

  • 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.

  • Cannot switch between multiple Time Machine backups

    I generally save my 2010 Macbook Pro to a 2012 Time Capsule, which is attached to my router via an ethernet cable (most recent) wireless. On a trip, I make the additional backups on an external hard drive. However, when I go home and try to return to the TC, my internal HD is now on the time Machine "Exclude" list and cannot be removed (greyed out). When I try to save, I get a message saying "no disks are available to back up."

    What has happened a few times, and the only solution I could find was to delete my original Time Machine backup and put a new (which took forever).

    Any ideas why my HD internal is added to the exclusion list after using Time Machine with an external hard drive?

    Time Machine backups on a network drive or a disc attached locally stored in different formats. Switching between them was not in the overall theme of the design of this service of OS X.

    I suggest that you set up Time Machine to use multiple disks.

    FWIW, in my case, I backup destinations, Time Machine on a Time Capsule and an external hard drive of 2 bolt of lightning. When both are available, the time goes 'take turns' Machine backup on each drive.

    If a disk is not available, it backs up to that which is, and which ignores the backup of the other. When the two are connected again, backups continue on both.

  • Cannot transfer Time Machine backups on the new drive

    I store my backup Time Machine on a Seagate 1.5 TB drive when the drive starts giving errors.  I had files on this computer and was able to transfer all except for 2 who were on unreadable sectors.  Fortunately, one of these files was an older archived version that I could afford to give up and the other was a temporary file in the photo library and since all other items were okay, I think I'm good.

    The problem came when I tried to transfer my Time Machine backup of 800 GB for a new disk.  When I copy and Exact-paste (cmd-opt-shift-v) the Backups.backupdb to the new drive, it gets the extent of November 23, 2015 and then dies because reports of the Console to the system, it gets an IO error when you try to read:

    /Library/SystemMigration/history/migration-245250B6-4F52-4FBB-BD61-546A8C19CCD5/ QuarantineRoot/private/var/db/dyld/dyld_shared_cache_x86_64

    in the relevant backup.  And because it's an IO error it simply abandons the whole process so I have no backup from November 23, included, for now.

    Because the disc is unstable, I wasn't able to use disk utility to make repairs on it.  The disc is what is and I have to deal with the mess, that I do not have the disorder, that I would have.

    I tried to manually place the missing files in the database, but the operating system will not let me.  I want to just copy my backup / OS X stop abandonment and be more like Windows and give me the options to "try again" or "fail" instead of just quitting!  I mean, why should I lose my backup all hierarchy of 23 November and beyond, simply because you cannot read a file, a file that I could simply replace in the backup of the current version or you can just ignore it.

    I tried to copy files on and setting xattr on them to be backup items, but they are wrong.  I tried chflags parameter to make the writable directory, but it does not work.  I can't copy the missing files to fix my archives.  Help.

    Please, don't try to transfer backups of a failed drive. Placing the disk aside until you don't know no longer you need the data, then delete and recycle. Start a new backup set on the new drive. For more security, you always have more than one backup.

  • Go new Time Machine backup drive

    I have searched the forums and have not been able to find the answer to this yet.

    It is my Time Machine backup on an external hard drive. I want to move it to a new drive and get rid of the old drive. But I can't find any information that explains how to migrate from one disk to another. Can I just copy the folder Backups.backupdb on the new drive? I'm guessing that's not as simple as that.

    In addition, on the "Ignore ownership on this volume" checkbox. I'm confused by what I read in the forums because it's kind of like a double negation. Once & for all, for this new album I want it checked or unchecked? And why?

    Thanks for your help.

    You can make a copy of the Finder to the new drive, but sometimes it hangs and does not work

    Try using disk/restore to copy the backup to a new location. Please note that this will reformat the destination partition.

    Checking ignore permissions usually eliminates any permissions problem which may occur.

  • Time Machine backup keeps causing MBP restart

    Hi all

    I'm a DJ and just more than one year, I bought a brand new series of mid-2012 13-inch Macbook Pro (non-retine) with an i5 2.5 Ghz processor.
    I installed a 750 7200 RPM HARD drive and max had the RAM to 16 GB with memory mac 'official' of CanComputers. I only use this machine for DJing. I have all my music in two folders on the desktop, I have 2-3 music applications and she. 10.9.5 running and I'm doing time machine backups every month.

    This month, my time machine was told the drive was corrupted and that I was able to read (it was a 500 GB Lacie Rugged). OK: I had another drive, a 1 TB USB3.0 Toshiba Ext HDD. 4 GB in the new backup, laptop computer suddenly shutdown, reboot and I get the message that the computer turns off due to a problem. I looked in the logs and nothing in particular stood out.

    I tried excluding my office of the backup and it worked - it supported a set of 3 GB. Then I added a little music on the desktop and excluded other files, and it has not yet. The entire backup is estimated to be about 450GB.

    I don't have time to play the files on this computer. Someone please tell me what I can do to solve this problem, or at least what is causing the problem. In the meantime, does anyone have an effective solution for the backup of these files?

    Thank you

  • Time Machine backup is not Backing Up all my files

    On my Mac, I used about 450 GB of 500 GB available on my hard drive (as shown in 'about my Mac'). But when you click on the Menulet of Time Machine with a Time Machine backup on an external hard drive, it says "Backing up 28.68 35,65 GB".  Why is it only backup 35,65 GB on my 450 GB of files & data?

    Thank you!

    Time Machine backs up only changes since the last backup on your Mac.

    The first backup, Time Machine copies on everything from the Mac to the time Capsule. After that, changes are saved with each pass.

  • New iMac, Time Machine backup

    I'm moving to a new iMac. On the new iMac, I can't use the Time Machine backup of old Mac. I "removed" the time of the old iMac Machine. Every time I try a backup on the new iMac, I get a "backup failed" the Time Machine backup is already in use. »

    He is a former...

    TM must control the sparsebundle to the backup... He must disassemble at the end of the backup cycle... and back at the beginning of the next cycle... I assume you are using a TC.

    The solution is to disassemble the TM properly... or to put it in simple terms... Restart the TC.

    I highly recommend not to inherit the old backup... but start a new... If the drive is not large enough we can make suggestions on get more space or recovering from it.

  • The merger with Time Machine backups

    I fear I know the answer to that, but would like confirmation.

    I am running Fusion 2.0.4 and have Mac OS 10.5.6.

    As part of support to replace a faulty card from the airport on my MBP, Apple did a new install of the OS and erased my disk. When I started the laptop I told it to restore from a Time Machine backup. He restored all the files under the My Documents folder, except for my virtual machines. He has even restored a text file I had in the 'Virtual Machines' folder, but not the virtual machines themselves. Looking back through the external drive for Time Machine, I don't see the virtual machines to any previous backup.

    I guess I'm watered at this point, although I'm hoping the actual VMs are located elsewhere, and under 'Virtual Machines' files are just links. Does anyone have an idea what I can try, or why the virtual machines are not saved?

    Thank you.

    Jeff

    If your virtual machines were in the "Virtual Machines" folder, where they are. Although it is possible to create a configuration where this isn't quite the case (for example, the link hard to another directory or volume), the simplest and explanation of the default value is that your virtual machines were either not stored (in this case I'm sorry to be the bearer of bad news) or in the first place never were in this folder (you can check your drive to backup files/folders - virtual machines tend to be big so should stand out).

    As to why it is, Time Machine in the first versions of Leopard would cause a deadlock (and hang the Mac) in certain circumstances, one of them was a virtual machine. To work around this problem, Fusion told Time Machine to exclude virtual machines. Apple has fixed the bug of Time Machine and deleted merge the exclusion of Time Machine, but it is possible to get into situations where virtual machines are still excluded.

    In general, we do not recommend the use of Time Machine to back up virtual machines - the short version is that it will go quickly through space and that it still does not produce a viable backup. Instead, we recommend that you back up files in the comments (or their mirror to the host and let Time Machine pick them up there), or manually back up virtual machines when they are not running.

  • 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.

  • 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?

  • 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.
