MacBook Pro :: Time Machine Does Not Recognize Backup Disk After Yosemite
Dec 12, 2014
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.

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.
Info:
MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.1)

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 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'm having a perplexing issue with Time Machine. Time Machine (the app) recognizes all the backups made to its drive; however, System Preferences doesn't recognize the last backups and won't make automatic backups to the drive. When I try to force a backup, it starts an entirely new backup (as in, separate folder and the whole system).
I just want Time Machine and System Preferences to recognize the backup that I've been running for weeks.

I just did a clean install of Lion on my 2.16 GHz Intel Core Duo iMac. Before I did that, I made sure that everything was backed up on an external drive through Time Machine. Now I want to restore everything and when I enter Time Machine, all that is visible for back ups are those that were done after the clean install of Lion.
when I open the files on the external back up drive through Finder, I can still see all of the back ups that were completed, including the most recent that I want to use to restore my iMac. I am considering another clean install to start the process again.

I got a new MBP (running Snow Leopard). I used Migration Assistant to migrate the data and setting from my old MBP (running Leopard) from my Time Capsule backup onto the new MBP. All went smoothly, and I used the new computer for a day to check all was well. This included testing Time Machine on the existing Time Capsule - all the old backups were there and it worked perfectly. the new computer also successfully added to these backups. So I wanted to refresh the old mac, so I booted from the old Leopard install disk, wiped the drive with Disk Utility, and did a clean install of Leopard. All was fine. Now I connected to the Time Capsule and attempted to use Migration Assistant to put a my stuff back onto the old computer. It wouldn't do this (couldn't see any backups). Does Migration Assistant only allow transfers from old systems onto new, not the other way round? This is a major bummer, if so. How can I get my stuff from my new computer back onto my old? Do I have to upgrade the old one to Snow Leopard in order to do this?

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 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?

I recently had my logic board on my MacBook Pro replaced and when I tried to backup, Time Machine did not recognize the old backup on the drive and tries to create a new one. The drive is mounted fine.
Is there a way to continue using my old backup, or do I need to delete it and create a new one?

Had to have the logic board in my Mac Pro replaced due to faulty audio input jack.
Time machine backs up to an external drive (DROBO array).
When I brought the machine back home, time machine does not recognize the old backup (last backup never) and doesn't have room to backup a new system because the old TM files take up most of the drivespace.
Is there a way to "force" time machine to accept an old TM backup file? I don't want to delete everything and start again. I assume this is because the logic board (motherboard) was replaced.
Note that the system drive and all internal hard drives were not modified, and the OS was not reinstalled or anything like that.
One other item: the tech forgot to run some software at apple and my machine currently has no serial number (about this mac...) assigned. They are sending out a tech to fix this - does time machine back up based on serial number?

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.

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?

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 ?

So I bought a brand new WD 1TB Elements (USB) to use with Time Machine. I've never used a Time Machine before. I have a MBP13 with a 250GB disk, using the latest Snow Leopard, all updates installed. Formatted the drive to Mac OS Journaled (extended) and set it to use with Time Machine. Works until about 15-17GBs is copied over, than it fails:
1. If I start over it fails very soon after, no matter how many times I retry
2. No matter how many times I reformat it, it always fails
3. I tried one trick I googled - deleting the "inprogress" file - does NOT help
4. SMART status is verified
5. There are no problems if I verify/repair the disk.

I want to use Time Machine, but I don't want to have all my data sitting in the open on an external drive that someone can just carry away. Can I make an encrypted disk image, and have Time Machine use that as the backup volume?

I just got a message that my Time Machine external backup disk is full. I have another external drive I can use, but buying drives every few months is going to get expensive.
I was wondering what others are doing in this situation.
Is anybody archiving the Time Machine backup? If so, what software are you using and where are you storing your backup?
What kind of backup plans are you using with Time Machine?
