OS X :: Use Old Time Machine Backup After System Reinstall?
Mar 24, 2009
I just reinstalled my system on a new system drive and then used the migration assistant to transfer *only* the user accounts and not the settings or applications etc. I wanted (needed) to start relatively clean. The system after all of this is very similar to the original system (same apps, same users, mostly the same settings etc.) and I would like to continue using my old Time Machine back-up if I can, but when I start Time Machine it just wants to create a new back-up and won't recognize the older back-up. I've read up about what to do if you get a new TM disk or if your have your logic board replaced, but this situation seems different. I can't figure out what would appear different to TM about my "new" system.

I got the fatal folder with with question mark and grinding sound of the hard drive when starting my 2008 Mac Pro this weekend. After some diagnostics it was obvious the Hard Drive is dead, of course its the main drive that runs the OS and all my apps. I am picking up a new drive today and was wondering the best approach to get it up and running again. Everying it is backed-up on my external drive through Time Machine. Since the drive is dead I can't use a copy cloner to the new drive. Would I install the the hardrive and start the Mac Pro to boot off the Leopard CD, intall that and then try to run the backup from Time Machine?

I just got a new 1tb sata 2.5in and I want to install it, but I do not have my snow leopard disk. If I use a leapord disk will it reinstall snow leapord from my time machine backup or do I need to find my snowleapord disk?

My MBPro is getting cranky in a number of ways that indicate a reinstall of Snow Leopard is in order. After the requisite disk first aid check I attempted to run the installer only to get a dialog box telling me that the system cannot be installed because this disk is used by time machine. The MacBook disk is of course a source for back ups but not a back up drive. Even after restarting and explicitly turning off Time machine I get the same results.What do I need to set to allow the installer to run. The installer cd is a stand alone snow leopard install cd, not a machine specific cd.

The Apple store sales person told me that I cannot backup my installed applications nor the OS with Time Machine. I have the latest version of Leopard. Lets say my hard disk crashes. Do I have to reinstall all the apps from scratch? Is there a backup program other than Time Machine? Should I be using dd?

When you set up a brand new Mac from a Time Machine backup, I know you get your applications, files, etc copied over. But what DON'T you get? For example, are there any settings or anything else that you will have to tweak again to make your new machine look and act like your old machine?

I decided to restore to a Time Machine backup I had done a few days earlier, hoping that I would just "start" fresh. Without realizing it, I had inserted the Leopard install dvd that came with my computer, and restored to my 10.6.6 backup. I got the "You must restart your computer" error, which I found out was a result of using the Leopard disk. So, I redid the restore using a Snow Leopard installer on USB.
After this, everything appeared to be working fairly well. However, today, I've started to get system crashes quite frequently, and at times I haven't been able to properly shut down or restart. I noticed that Spotlight was indexing, and would hang at "3 hours remaining" or "estimating time left." Right now, I have created a second admin account, and I have disabled indexing. It seems to be working, at least temporarily, because I'm using it right now.

I am going to backup the main system drive though. I'm thinking shall I use Time Machine to back it up or use a 3rd party application to back it up and make it boot-able at the same time?

I've upgraded to mavericks. Everything works fine except Time Machine. I want to continue using my 'old' time machine backup on an external server. When I try to reconnect I get the following message: The disk image "..." is in use Try ejecting the disk image.
I have disconnected and reconnected to the external server. This had no effect. At first glance it seems I am able to access my old backup clicking "Browse other backup disks". But the I don't get my backed up files. It's stuck at today Â

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 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'm running an iMac (one of the all-white, 1.83 GHz C2D machines, with 512MB RAM) and i've noticed in recent months it's become outrageously slow, i have no idea why but it's just horrendous.
I'd really like to start afresh with a clean install of Leopard, but only if it will make a difference.
Currently i'm finding that even with 2 apps open (eg Mail and Safari) there is serious lag now and again, and sometimes things lock up completely. Is this just a bloated OSX install or signs the computer is dying?
Anyway, i have a 180GB backup drive currently used for Time Machine, but if i reinstall then restore from that drive, won't it just restore all the bloat?

My Macbook Pro hard drive failed. It is completely unrecoverable. I've purchased a replacement. How do I format the drive, install Lion and restore my system from my Time Machine backup? My Time Machine backup was created from a USB connection directly to my Macbook Pro. I have a Apple Lion USB Install Thumbdrive.

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. Â
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. Â
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.Â
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?

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.

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???
Some quick screenshots:

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.

There are 3 macs:
A: an old macbook (the white one)
B: a modern macbook pro (retina)
C: another modern macbook pro (TBD)Â
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've got a Macbook Pro with Snow Leopard installed, but it has been going sort of sluggish lately so I've decided to do a clean reinstall of Snow Leopard to try and improve things. I've got an up-to-date backup with Time Machine to my Time Capsule. When I do a clean install of Snow Leopard, will I be able to easily restore the files that I want to keep and the applications that I want to put back on my system (with their settings)?

Say my macbook pro crashes and I lose everything. However, I have been saving everything to an external drive using the Time Machine app. Can I use my external drive to get my computer to exactly the same state it was in before it crashed? By this I mean.
1) Desktop icons in the same places
2) System preferences all the same
3) Sticky notes all still exist and are laid out on the desktop just like previously before my hard drive crashed and I lost everything
4) My dock layout is exactly the same, same apps, same locations in the dock
I have been wondering this for quite some time. Because I know you can restore the essentials (i.e. Word documents, many different saved files) but what about little things like the above mentioned items?

So I've got a unibody MBP and connected to this I have a 320gb external drive I use to back up, but I only back up music, movies and documents so it's got 50 free gigabytes. I was hoping to partition off say 30gigs, install tinyxp and play games off this partition. But when I try and partition off 30, 25 or even 20 gigs Disk Utility tells me there's no free space on the hard drive.
So my questions are, how can I solve this issues, and would this idea work for playing games through windows anyway? I initially tried to get a bootcamp partition on my main Macintosh HD, but apparently there are files that cannot be moved in the way, and the only way to solve said issue is a complete reinstall of leopard, which I can't be bothered with seeing as snow leopards only a couple of months away.

I am going to replace my hard drive (and add RAM) on my Macbook Pro (mid-2009) myself. I have Lion (10.7.4) currently, and have backed up via time machine on an external drive. I don't have Lion on a usb, and from what I read, Lion Recovery via internet isn't applicable for my macbook (pre 2010). Is the time machine backup a bootable drive? If so, then am I all good so long as my backup is completed prior to replacing the hard drive? If not, how do I create a bootable drive so I can get back to "normal"?Â
