Applications :: Unable To Create Backup / Time Machine Stops Working
Sep 10, 2009
I have a mid-2008 (June) MBP 15". Just upgraded to SL last night. I am having a serious issue with time machine. I've been using it with the same external HD since I bought my mac last year. No issues up until I installed SL last night. This morning (my first backup since upgrading), time machine started backing up (~ 9Gb) but just stops at around 300Mb. The clock keeps spinning, but there is no change in the amount backed up.
I'm reading that other folks are having this issue as well. Has anyone figured something out?I've run disk repair (nothing found), restarted my mac & external HD (several times each), and cancelled and restarted the time machine backup (several times). Each time it freezes at a different amount (i.e. 34Mb, 284.2Mb, etc...).

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?

So I finally got around to getting a 1tb drive to hook up to my airport extreme to do TM backups. I have ~420gb to backup on my mbp's hard drive. To avoid an absurdly long backup, I did the initial backup via usb (took the better part of the day).
Just now I was excited because it finished - I hooked the drive up to the extreme, mounted the drive so that it would show up as an option in the TM pref pane for a backup disk, and thought I was good to go. However, when I tried to get TM to do a backup so I could see it work (by selecting Back Up Now from the menubar), it took a ridiculously long time "preparing" and I saw that it was trying to create a whole new TM backup on the drive based on my computer's network name. It even had the audacity to think that the previous backup file was ~2gb, which freaked me out because I thought it had deleted it. But sure enough when I canceled the new backup and hooked it up to my mbp again, the backup was the correct size.

I have a mid-2012 MacBook Pro running Yosemite 10.10.1 that has started something. Here's what it is doing:Â
When I connect my external HDD for Time Machine to my MacBook Pro the internet stops working. By not working I mean, it is stays connected to the WIFI router with a full signal, but the internet, for lack of better words, ceases to function. I can't browse online, any app - like Mail - that uses the internet loses connection, and even background apps running on the top bar loses connectivity. If I run a Time Machine backup, eject the Time Machine external HDD, and pull the USB cable out of the MacBook it instantly goes back online and continues as normal.Â
I've checked settings, excluded Dropbox and OneDrive from being backed up in case they were conflicting in some way, and have searched for any answer anywhere I could think of.
The external HDD I use for Time Machine is 750GB and is the same HDD that the MacBook Pro came with originally (I swapped HDD to a hybrid drive internally and put the original HDD into an external HDD enclosure which has been solid for me for over 2 years now).Â
Info:
MacBook Pro, OS X Yosemite (10.10.1)

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?

I have two computers using one Time Machine Disk. The physical disk is connected to my Mac Mini, and it's shared over the network to my MacBook Air. The picture below is the backup disk in case you didn't guess. The notebook is my MacBook Air. So the MacBook Air backs up just fine, but every time my Mac Mini tries to back up, it pops up with "Would you like to reuse the backup "*DIRECTORY TO MACBOOK AIR'S BACKUP*" with this computer?" also shown in the picture below. So I click "Create new backup" and it seems to backup in the Mac Mini's backup folder like it should... until next time. I just want it to back up normally, both of them, without asking me anything first. Until now, I've just disabled automatic backups for my Mac Mini and would backup whenever I felt needed.

I'm using Mac OSX 10.7.3. Since a few days, I've some trouble with Time Machine. When TM would create a new backup in the normal hourly loop it creates the message: Time machine has completed the review of its backups. To improve the reliability time machine must create a new backup.
Now I've to options:
1. I can create a new backup later
2. create a new backup
I don't want to create a new backup, I want to use the old one. I still have enough space on my backup volume. I'm using the Airport Extreme and a WD hard drive.

MacBook (13-inch Aluminum Late 2008), Mac OS X (10.7.3), Time Machine

After updating to Lion server, I moved my Drobo over and setup Time Machine
Many users are prompeted to reuse or create a new backup.
The problem is I log in with credentials of 'USER A', and on the dialog it lists another 'USER B', userb.sparsebundle as the file to reuse. Â
I recently had a iMac hard drive die, and i tired to use the time machine on the server, with 'USER A' credentials, i got 4 listings and none of them were 'USER A'Â
I check the drobo and 'USER A''s sparsebundle is there. I have tried changeing permissions to read the sparsebudle, but the bundle is a 250k file, not a diskimage of the files even. Â
How do i resolve this problem of the wrong users coming up on "reuse or create new backup"?Â
How do i access the lost sparsebundle that i cannot log into to get the files for the user that needs them?
Info:
Mac OS X (10.7.4)

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???
Some quick screenshots:

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 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.

So I have Time Machine syncing with an external drive and its been backing up perfectly without a problem for the last month. I have not plugged in the external drive in a week, but when I plugged it in to backup today, time machine will not back up to it. The computer sees that the drive is there and identifies at as the Time Machine drive but will not backup to it. The external drive is not full and there is no damage on it. Also, in the time machine system preferences window, the oldest, last, and next backup dates are all blank, they were filled before.

It's weird, time machine use to work fine. I have 3 HDD connected to my computer, and one of the slaves is mac journal case sensitive. Backups have been fine for the last couple months. However recently, time machine will not back up exactly a chunk of 222gb of data. When time machine gets to that point, it just stops. No error message no nothing. And at the top, it says "waiting for backup." Nothing else. I reformatted the hard drive guid, mbr, case sensitive etc etc, nothing. I even swapped out the external hdd and same problem.
How do I troubleshoot this or find out what is causing the problem? Is there a particular format time machine doesn't want to backup? Is there a partition format type time machine doesnt like?

I'm in the midst of moving from a 2011 imac to a 2014 - I have/had 3 TM backups  1) before the 2011 crashed and was repaired - 2) from the interim 2014 imac that I restored and updated for the new computer and 3) a "carbon copy clone" of my current drive because the apple tech made me wipe the drive and start over and it failed. Â
My computer will be here next week and I wanted to prepare.  However since the restore of the repaired 2011 NO TIME MACHINE will back up on ALL 3 drives the same error happened.  It would start fine and say it needed 17-22 hours to "create new" or "inherit" and would start fine and then freeze somewhere around 15-20GB?????   I left it more than 6-7 hours and the freeze remained. Â
Need a TM expert...... this HAS to be a Mavericks OSX issue and I do not want to wipe another drive. Â

I have been trying to backup my computer for the longest time. It has been stuck on (53.4MB of 62.5MB) for about 45 minutes now. Any ideas? It is on an ethernet connection.

It just says "Preparing Backup..." It stays like this forever until I stop it and I tried re-connecting the hard drive. Why won't this work? I tried re-starting...

I have an Imac 24" and a Mybook external HDD. ever since Leopard came out Ive been doing backups with time machine, then one day I start time machine for my weekly backup and this message comes up: "Unable to complete backup. An error occurred while copying files to the backup volume." Now I notice that my external HDD was almost not spinning while time machine was trying to backup the status bar of time machine saying how much files need to be copied and the total amount of space needed was super slow and stoped at something like maybe 10 mb I started time machine again same message. I though maybe Mac OSX needed some permission repaires. So I did just that and after that did time machine again same problem. then I said to myself maybe my External HDD has problems so I even formated the HDD, then stated Time machine again this time it was running smoothly just like before I had the problem but the problem came back after 6 gig being copied out of the 25 gig needed to complete the backup process. Now hope I dont need a clean install of my Mac OSX or maybe its my external HDD. maybe my USB having problems?

I recently used time machine for the first time in a long time. I use my external HD USB for the backup. After the back up was complete, I unplugged the USB cable. I got an error that I needed to put the HD away first (I wasn't thinking). And I didn't pay attention to the error either.
I thought the data was gone, when I didnt see the data in the back up file. I do see the back up file with that date on it. In the file is the .InProgress file. In that file, on right clicking, I see the contents of one folder. This folder has a very long name of numbers and letters. It shows no contents in the finder. THough I know the files must be here. The HD has capacity of 100 Gig. There is only about 20 gigs showing on it. Though there is only 20 gigs available. So, my back up data is there on the HD, and I assume it's in this "empty" file.
* How do I extract the saved files ?

I have 10.4.11 installed and have some time machine backups from a leopard system on one of my externals. When I try to navigate to one of the backups and get into any of the user folders like documents, pictures, etc it says I don't have permission to access them? Yet I check the permissions and they are read/write.

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:

I did a restore from a Time Machine backup. Now my iTunes Artwork screen saver isn't working. I'd try to do a reinstall from the Time Machine again to see if it still is a problematic, but I was an idiot and deleted it and backing up fresh. I've repaired permissions. I've gotten album artwork. My music folder reads like this. User/Music/iTunes. Inside are two folders. One "Album Artwork" the other "iTunes Media." Inside the "Album Artwork" folder is "Cache" and "Download."

I've purchased a 2TB external drive, I downloaded and installed macfuse and ntfs-3g AND tuxera ntfs and I formatted the drive to ntfs. Everything was working perfectly (reading and writing) until I unplugged the drive form my computer. So when I plugged the drive back in, it could only read and no longer can write information.
What is going on? I didn't even turn off my computer, the only thing I did was backup my computer with time machine (onto a separate drive not the NTFS one) and plug the new drive back in. I've reinstalled all 3 programs and restarted my computer but nothing seems to be working.

I've spent a good deal of time over three days trying to do something that I think is both doable and shouldn't be all that hard. I have a 750gb external HD attached to a Mini, and I'd like to use that drive to do TM backups for the Mini, as well as three MacBooks.
But I can't seem to get access to the backup drive from the laptops to either get going in the first place, or to remain available for TM. I get "volume can't be mounted" errors, "image can't be mounted errors", etc. I find that I can't ever eject the backup drive from the Mini (always told an application is using it...even if I've just booted up the Mini). And with one of the MacBooks, even a direct FW connection to the drive doesn't result in the drive showing up in Finder.
Isn't this a pretty straightforward thing to do? Is there a step by step somewhere that might help me figure out what I'm doing wrong, or what I need to fix? Should I reformat the drive again and start over (there are no important backups on it yet)? By the way, the drive is formatted Mac OS Extended (Journaled).

I'm having trouble backing up with Time Machine. Here's the setup:
1. Three, 1TB external hard drives in a concatenated software RAID. This means that they are treated as one large drive. There is no mirroring, no increased data rate, blah blah blah. It's just three hard drives in the place of one. I am aware that this means my backup is three times as likely to fail with the hardware, but that's OK.
2. These three are connected to a USB hub.
3. This hub is connected to a G5 tower. The G5 tower can back up to the concatenated drives (I'll call them just a RAID from here on), and also all additional external hard drives that I connect to the G5 tower have been backing up to the RAID no problem. This is great.
Here's the problem:
I'm trying to get two more computers to back up to the RAID wirelessly. I read a lot online about how this didn't used to be a supported feature (backing up to an external hard drive over a network with time machine), but that Apple has recently upgraded Time Machine to support this functionality.
The first computer I started with to try to backup over the network was a Macbook Pro, trying to get it to backup to this RAID. It can see the RAID over the network, mount it, copy files to it/read it, but CANNOT time machine backup to it. I select the network RAID as the backup device, hit "back up now," then get this message:
"The external volume cannot be mounted."
This is really bizzare, considering that it is mounted, and that I can copy to it. Just for your information, I have an airport extreme wireless network that has been working beautifully, no Keychain access issues, no 3rd party firewall, nothing. I've run through Applecare on this issue: the MacBook Pro has never done ANY time machine backup on the RAID, not even a partial one, so there's no dangling sparse bundle or backup folder or anything like that. All network permissions check out, etc. I've tried repairing the RAID with disk utility, as well as repairing permissions (although I have not done either of these things to the MacBookPro).
The latest thing I tried was plugging the RAID directly into the Macbook Pro. Here's where I got the first clue (at least I think so)...Plugged DIRECTLY into the MacBook Pro, the RAID will mount, but the MacBook Pro WILL NOT backup to the RAID. It gives me the same message: the selected volume cannot be mounted. Again, this is strange considering that, just like when I am viewing the RAID over the network, plugged directly into the MacBook Pro the RAID will mount, I can read it, copy files to it, etc.
I have considered plugging the RAID into the Airport extreme directly, but first of all this would mean much slower transfer speeds with the G5 tower, which is a big issue considering the files I am backing up every day, and two, since it seems that the RAID won't be recognized by the MacBook Pro even when plugged in directly, I'm thinking that this is a more fundamental issue.
