OS X Yosemite :: Time Machine Won't Backup MacBook Air
Nov 30, 2014
I have a Mac Book Air with Yosemite installed. I also have Time Machine backing up to a Time Capsule. Plus, two other Macs are backing up to the Time Capsule. The problem I am having is that the Mac Book Air backups are not working. It keeps say "Preparing Backup" then after a while it says "Stopped". I have tried deleting the "In Progress File" but this has not worked. The other backups on the other machines seem to be working fine.

I have this issue in both macs I own, a 2010 MBP, and a 2012 Mac mini. After I upgraded to yosemite, Time Machine will not find my backup disk. I have been using the same network attached storage drive for 4 years for time machine backups. I has worked fine with all the macs I've owned until now. I can see the disk in Finder, I can go to disk utility and mount the Time Machine disk, but when I go to Time Machine preferences and try to select the list, the disk is not listed there, even though is mounted.

Is there a way to modify the frequency of Time Machine backups without just turning it off for a period of time. I.E., can I tell TM to backup every 3 hours instead of every hour? Running Yosemite 10.10.1 on iMac (27-inch, Late 2013).

I have a Mac Book Air that has been backing up to a Time Capsule. I do have other Macs backing up to the Time Capsule which work fine. For some reason it is saying the last backup was the 9th of November. I thought maybe this has something to do with the lack of space. So I have added another disk to the Time Machine and I am not sure whether it is backing up to this one as it is saying the "Backup is incomplete".

I am doing a backup prior to my first ever format & reinstall. Time Machine will not allow my use of this external hard drive that I had previously used for a Time Machine backup . Time Machine says, " The backup disk is not in Mac OS Extended ( journaled) Format, which is required." how do I change it to Extended (journaled) Format?
Yes the external hard drive in question is meant for Mac.

I am trying to organize my external storage for a new iMac with an 500G SSD drive. I have a new thunderbolt G-Raid drive and an aging Airport Time Capsule. I was thinking of storing music and pictures, as well as a Time Machine backup of the SSD, and storing a Time Machine backup of my music and pictures on the Time Capsule. Will I need to partition the G-Raid?

My time machine hasn't backed up since November 22. Every time it went for it's scheduled back-up it skipped and went to the next scheduled backup. When I tried to reconfigure the time capsule it won't let me select the disk that I would like to use for the time machine. Everything else is working fine (airport wifi at least). Here are some screenshots:

Am I understanding correctly (from reading some other discussions here) that there are issues with Time Machine back ups and Yosemite, and that it's not just me having these problems? Since I upgrade I am having major issues with wifi connection being dropped and my Time Machine hasn't performed a back up in 19 days. It looks as though it will but stalls at "preparing back up". When it finally stops I get an error message saying it can't find the disc. I've restored the Time Machine to factory settings and started over more than once but still get the same message. Am I doing something wrong or is this an Apple issue?

Each time im doing a time machine backup, the external drive does not eject, the icon becomes pale, but remains on the desktop. But when I did not just make a backup I can eject it normaly.
My disc contains two partitions, one with the backups. When my problem occurs the first partition is ejected but not the Time Machine one.
I tried to reformat the partition but the problem persists. My hard drive is a GDrive mobile usb 1 TO purchased at the apple store.

I want to upgrade my macbook pro to Yosemite (I have mavericks installed). The Apple guy recommended me to backup. So If I backup through time machine ON my Mavericks macbook, Will I be able to restore it on Yosemite after installing it ?I am asking this because time machine captures the "look" of Mavericks and Yosemite looks different. Will the (Mavericks)backup be compatible to Yosemite ?

I have looked into this a lot already. It is to much that Time Machine backs up every single hour! It would be nice to set it to something like 3 or 5 hours. I have tried a 3rd party app to do this, but... If my computer was off or asleep when it was supposed to back up, it would get an error. It would not just do the backup when i turned it on or when it came out of sleep like stock Time Machine does. I have also seen a way to change the time incraments in the Terminal.(I am very good with it, not a noob) I have tried this and it screws up time machine completely. Maybe it does not work with the newest OS X. By the way... I have a 2010 MacBook Pro, got it 2 months ago.
Does anyone know a solid 3rd party app, that will work seamlessly. Or has anyone changed the time in Terminal and are currently using something different than 1 hour. There is a lot of examples online, but I would like the codeing that you literally used.

Just wanted to check if he problem was unique to my MBA (Rev B, HDD) or you notice it too ;
My Time Machine backup takes up to 6 hours to do a backup of about 30GB. And each backup size is 31.5GB everytime !!
I have the following Config - 80 GB for OSX (53GB Free) and 40 GB (10GB Free) for Win 7 on Bootcamp. Sometimes I wonder if TM making a backup of Win 7 also everytime. (Does it mean - In a way its good, that means I should be able to restore the entire hard disk from TM including Applications, Win 7 , bootcamp and all the programmes installed in Win 7 in case I have a problem ?)
But the speed should still be fast... 6 hours to do a 32GB backup is torturous specially because then I have to leave the machine alone and cannot use it.

I am getting the following error from Time Machine when doing my first backup. The startup disk being backed up, and the TM disk are both the same size.
Macintosh HD: 465.44 (total); 393.99 (free); 71.45 (free)
Time Machine: 465.44 (total); 465.29 (free)
The Time Machine error is: Quote:
"This backup is too large for the backup volume. The backup requires 472.7 GB but only 465.3 GB are available." why would this be? Other disks are excluded from the backup, and Time Machine is telling me that it needs more space than it actually needs. What should I do?

There are 3 macs:
A: an old macbook (the white one)
B: a modern macbook pro (retina)
C: another modern macbook pro (TBD)
I am giving away B now; I expect to get C in 2 months time; I keep A with me all the time.
The goal is to migrate all of the data from B to C. I have Time Machine backups of B.
Since the transition is a long time (2 months), I need to keep working on my data during this period. For this I will use A. This will generate new files, modify old ones, ...
Since A's HDD is much smaller than B's backup, I can move only part of them.
By the way, I have totally erased A and used migration assistant to restore part of my old data from B. So, when I use A now, I do it with my same account as in B (and the same I will use in C).
How do I manage my backups in such a way that, when I will get C, I can safely move all of the data I had in B plus all of the changes and modifications that I have done during the 2 month transition?
Can I just continue to use Time Machine (on A) to update the old backups? I am afraid that some mess could be created because the computers are different (before the backups were taken on B, while now on A), even the present data are different (because now A only contains a subset of the original B data, which I do NOT want to lose), the good point is that the user is the same.

I was a PC user who recently moved to mac. I have a macbook (intel 2.2GHz, 2GB RAM, 250GB HDD). When I was using PC, I backed up all my data to a network storage device (Buffalo LinkStation 250 GB connected to a 802.11g netgear router which is supplied by Sky) using a program called SmartSync Pro, which worked very well. Although I can connect to and mount the Share folder on this drive when the macbook is connected to the network, Time Machine will not back up to it. It wouldnt even recognise the disk on the network.
So I went onto the trusty internet, and found that you can get time machine to recognise the Share folder. (This was obtained from: http://blog.imulus.com/george/software/using-leopard-time-machine-to-backup-of-a-network/)See my comment on their page at the bottom, number 66.
It recommended entering the following in to the Terminal: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Before attempting backup I have to go into "Network" and select the Share folder by double clicking on it. This seems to mount the volume. After this, it can be seen in Time Machine as a potential backup destination.
However, this method does not work for me. Time Machine "prepares" for a while, then gives the following message: Time Machine error. The backup disk image could not be created.
More internet searching took me to macosxhints which suggests creating something called a sparsebundle image on my local system. (http://www.macosxhints.com/article.php?story=20080420211034137) Have not tried this yet as I thought it would be prudent to seek some help first.
Apple have deliberately disabled the ability for Time Machine to back up to network attached storage, (except of course to their proprietory Time Capsule):
Is this because time machine requires a network faster than 802.11g?
Is this because a time machine backup to a network attached storage device is unreliable and the data is corrupted?
I dont want to shell out more cash for a time capsule. I would prefer not to have to hardwire to an external drive (which I will also have to go out and buy). Any thoughts?

I just purchased a Seagate 3 TB USB 2.0/3.0 external drive to use as my time machine backup drive. I have a MacBook Pro that was purchased about 3-4 years ago. The MacBook Pro has a 120 GB hard drive and is currently running MAC OSx 10.6.8. I also have another WD 1 TB FireWire external drive that I use to store all of my media files.
After I followed the instructions for installing the new Seagate drive for use with the MAC OSx, I initiated a time machine backup. It very quickly determined that it needed to back up almost 900,000 files totaling just about 400 GB. It started the backup process at a rate of about 1 GB per minute. In a little less than an hour it reach 53 GB and remained there for an additional two hours before I decided to stop the backup.
Once I got the backup stopped, I deleted the backup and decided to look at my energy saving settings. I noticed that the "Put drives to sleep whenever possible" check box was checked, so I unchecked that option and restarted the MAC. I then initiated the time machine backup again. Like the first time it quickly determined that it needed to backup the same amount of data as before and started the backup process at a rate of about 1 GB per minute. Before going to bed at around 11 PM last night it was at about 60 GB so I thought I was out of the woods (having gotten further than the 53 GB earlier). When I woke up this morning at 5:30 AM it was sitting at 69 GB.
I am really frustrated at this point and don't know why the time machine back up would be failing on a brand new hard drive. PS - I was previously using a Seagate 1.5 TB USB drive as my time machine backup and never had any issues with it. I decided to use the 1.5 TB drive for a different purpose, which is why I have the new 3 TB drive to use as a backup. And I still have the full backup on the 1.5 TB drive just in case anything were to go awry.

I have a external HD which has always worked fine under snow leopard. Since upgrading to lion I keep getting the following message The identity of the backup disk has changed since the previous backup.The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk. And after this the drive disappears from the desktop appearing agian only after restart. What can I do do rectify this? Delete and re-intialise the drive?

Is there a way to make a backup of your Time Machine backup on a 2nd hard drive? I want to be doubly sure that my data is backed up!Right now I get an error saying that the second hard drive isn't authorized to copy my Time Machine data from the original hard drive I have set up as my Time Machine.

I just replaced my HD on my 15"MBP. The install went well until restoring my data from Time Machine. The apps came over fine but none of my data did. Yes, I checked all the boxes on the "restore from backup" menu.
Of course now when I start up time machine the backup isn't there. How do I get Time Machine to recognize the backup? I have it on two places - a time capsule and a separate external HD.

I just replaced the stock 160GB HD in my unibody macbook with a WD Blue Scorpio 640GB HD. I used Super Duper to clone the old drive to the new one, approximately 115 GB.
Now Time Machine wants to backup the full 115GB to my Time Capsule, which kinda sucks because it's going to be a redundent backup that's gonna take up over a 10th of my TC's space. Is there any way to avoid this and still use Time Machine?

I have a 1tb external for time machine back up and have about 750 gb of stuff to back up. I was under the impression that when time machine backs up my stuff it will automatically delete the oldest backup to create room for the newer backup.
My problem is that i did a back up a couple weeks ago and then today i go to back up and it tells me back up failed only 718gb available for 740gb of stuff to back up
anyone have this problem? how can i fix it?

Well TM is acting up. I get an error that reads: "This backup is too large for the backup volume."
Both the internal boot disk and the external baclup drive are 1TB. The internal one has a two partitions, the OSX one that is 900GBs and a 32GB NTFS one for Boot Camp. The external drive is a single OSX Extended part. that is 932GBs.
Both the Time Machine disk, and the Boot Camp disk are excluded from the backup along with a "Crap" folder for temporary large files.
Time Machine says it needs 938GBs to backup only the OSX disk, which has 806GBs in use with the rest free. WTFFF?
This happened after moving a large folder (128GB in total) from the root of the OSX disk over to my Home Folder.
I have reformated the Time Machine drive and have no backups at all of my data and it refuses to backup!!
Why would it need 938GBs of space to backup if the disk has "only" 806 GBs in use??? Is there anyway to reset Time Machine completely???

my TM wil not back up! It states that this backup is too large for the backup disk. The back up disk requires 573.50 GB but only 225.23 GB are available. The TM needs work space on the backup disk, in addition to the space required to store backups. Upen TM perferences to select a LARGER backup disk or make the backup smaller by excluding file.
Okay I;m sorry but obvioulsy I dont get this. I've never called Apple for help! I have every product they sell practically including Protection Plans I never used and no one will help me with this. My MAC is starting to have black or white screens and i can hear it running but it will not do anything so i have to reboot it, it screws up Enturage and then I have to rebuild that ( 5 times this year) anyway... I would like to back everything up- can I delete everything on the Time Capsule or Time Machine; god I dont even know what it is called Im so MAD... help if you can please. I'm going to have to take this to the genius people at the store and probably buy another computer but like before they will not save my files.

With previous versions, a reminder popped up if you have not run Time Machine in 10 days. That seems to me missing once I upgraded to Yosemite. Is there a preference adjustment I missed?
I am using Yosemite 10.10.1 which I believe is the current version on my MaBook Pro
