OS X V10.7 Lion :: Time Machine Backup Is Too Large For The Backup Disk?
Feb 10, 2012
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.Â
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.

What if a Time Machine backup was created on a Mac with a large hard disk, e.g. 500GB iMac - and I buy a new MacBook Air with a small SSD hard disk e.g 128GB. What happens when I need to use the larger Time Machine file to set up the new MacBook Air? What happens to all those files that can't fit on the smaller SSD drive?

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 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?

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've been having a problem with Time Machine lately (OS 10.5.1). My computer is set up as follows:
Internal iMac HD
Firewire external HD (music)
USB external HD (Time Machine)
I have Time Machine back up the internal and firewire (music) drives. The initial backup takes up appx. 290GB of my 500GB TM drive. Subsequent backups function as normal, until a restart.

I have port forwarded port 46 (TCP and UDP) to port 548 a Mac mini server running Mac OS X 10.6.8, and I have Time Machine backup disk on it set as a share point with Time Machine support enabled. On my Mac Pro running OS X 10.8.5, I am able to connect via AFP to my server with the address "afp://my-ip-address:46" and can read and write on the backup disk share point. I tested that, and it works. When I am on the same LAN as the server, I can use that disk for Time Machine and have been doing so for years. However, I cannot do a Time Machine backup to that share point over the WAN. When I open Time Machine preferences, I can select the share point as my backup disk, but once I start the backup, it says "Backup disk not available" and fails to start.
In case you're wondering, I forward port 46 to port 548 instead of port 548 to port 548 to minimize hacking attempts. Last time I used a default port, a computer in Taiwan started spamming SSH authentication failures.

I am using Time Machine with my external drive. And since my external hard disk does not have too much capacity, from the time machine options I excluded some folders like movies, music etc. So in time machine preferences it seems it needs 42gb for backup. And it was working like this, backing up 42gb and everyday just backing up changes like 100mb. So in hard drive more or less 50gb was used..70gb free. Until last week.
Suddenly it appeared an error like this "This backup is too large for the backup disk. The backup requires 128 GB but only 97 GB are available". I do not have any idea how this can happen since my backup size seems like 42gb still in options. How it can require 128GB suddenly? Also how can I have 97GB available? I had 70GB last week? I tried to include everything in backup options and exclude again but it does not work. Still I see there 42gb needed for backup but when I connect the drive I am still getting the same error!

Is there any way to find and delete large "unwanted" files from a Time Machine backup on a Time Capsule? Lets say you have some big ISO-files you want to remove but don't know at what date they were backed up.I tried to mount the Time Machine backup image and locate big files with GrandPerspective but it didn't really work.

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.

Is time machine already/still supported on current OSX 10.7, or is it already deprecated as it was introduced several releases ago? When I try to activate Time Machine on my all new OS X Server, I get a dialog "Choose destination volume for client Time Machine backups:". I choose a volume, and the message is displayed "This disk drive may not support Time Machine backup over the network. Get more information about compatible drives."
"More information" links to [URL] which just provides commonplace advice to not disconnect drives while the drive is in operation. The support article is marked as archived and no longer updated after 10.5. The promised information is not provided. Is there anything obviously wrong with the setup?
Mac Mini Server, OS X Lion 10.7.3, 2x750 internal disks as RAID1, new of this month
External drive: 3TB USB3 Maxtor, single partition (repartitioned for GUID), connected via one of the internal USB2
The external drive is also used as Time Machine for the Server's local volume. I have read recommendations to use separate partitions per client, for time machine solutions using a third party NAS. Instead I chose the original - am I wrong to assume that the OS X Server's Time Machine service is able to manage multiple clients?

Moved all my movies audio etc and stored on external HDD, but as I have lion and time machine it saved a local back up so that when time machine was synced it didn't miss anything.Seems sensible, so next step was to sync time machine, expecting that the local back up would disappear when it shifted to TM. It didn't...why in gods green earth is the local back up there even though TM connected the whole time and up to date? Â I've restarted, loaded all updates and verified disk. How do I get to the "it just works" part without having to Delete this double up (32GB "backups") via terminal etc....

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.

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'm interested in replacing my 250GB HDD for a 80GB SSD. I want to use the old drive as a USB backup disk for Time Machine, but is 5400 RPM fast enough for this?

I'm using 10.5.8 and Time Machine on a time capsule which should have enough space. I've unchecked the "ask before deleting" option in Time Machine but no dice. I suspect that the problem stems from when I copied my iTunes folder into my public folder so that I can share among user accounts. It's not a copy of the folder but rather I moved it. Still, I think that time machine is trying to hold onto two copies.

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 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?

I'm no newbie but this one has me stumped. I can put file onto a Time machine backup disk that I don't use as a backup anymore but I can't take them off. The Disk still has some backups on it that I would like to keep. But I would like to use the extra space for regular file storage. What gives. When putting a file on the disk it asks for the password but moving them to the trash it will delete everything in the folder but it won't actually delete the root folder. So my question is
1. Can I use the disk and keep the backups on it?
2. How do I get permission to read and write to the disk

I have the new Time Capsule and am able to access it remotely just fine. However, because I'm stuck at school all day, I rarely get the chance to back up my Macbook Pro. Does anyone know of a way to have Time Machine backup to a remote disk, such as my Time Capsule? (I'm a Mobile Me subscriber, by the way)

I had to give up my Macbook Pro and am now going back to my Macbook. I have everything loaded on a Time Machine backup, but am having trouble getting to my Macbook. I bought a Leopard Install DVD back when they were released, but when I pulled it out I saw it is now scratched. Can I use a Macbook Pro Leopard install disk to restore my Time Machine backup to a Macbook? If not, is there any way to completely restore a computer from a Time Machine backup without an install disk?

The problem is that full Os backup should be about 155 GB, but it tries to backup whole disk 1 TB. It works fine for first full backup 155 GB (I have exclude list) after that it wants to backup whole disk no matter what. No such problem with 10.6.2 just with 10.6.3. Image so we are clear. I'm new to Mac OS X.
