OS X :: How To Retrieve Data Accidentally Overwritten By A Time Machine Backup
Apr 14, 2009
I connected my windows removable disk to my colleague's mac to transfer some data. Accidentally her system started a time machine backup on my removable disk. Although we stopped it during middle of the process, now my disk is no longer recognizable in windows and all I can see under a mac system is her backup file.
The process took a very short time. I wonder if it has deleted everything. Is there any chance I can get the overwritten data back? They are very important to me.
Besides, is it a common problem of time machine backup? It is too dangerous for the removable disks.

I have a file I alter once about a week, each time I alter it I save it as a new one, with a date included in the name.So I have a series of files something like
xxxxx march 13.numbers
xxxxx march 07.numbers
xxxxx march 01.numbers
etc.
This morning when I updated and saved the march13 file I accidentally saved it as xxxxxx march 13, not xxxxxx march 20 which it should have been. No problem, go into time machine and retrieve the march 13 file I thought.Its not there. Its not there from just before the save to any time it should be there !
Luckily I was able to retrieve it as I also have a once a week online backup so I went into the last one of those and retrieved "xxxxxx march13" which proves it did exist, it has a creation date of march 17 but if I look at TM for march 18 its not there - why isn't it in my time machine backup?
All the other files in that folder are as expected so the only thing that makes any sense to me is that TM hasn't been backing up over the past week or so but TM error logger shows no errors.

After a catastrophic HD crash I bought a small 250GB external hard-drive an started to use Time machine. Since my Mac was freshly formatted, I tend to keep it tidy and clean and keep good track of what comes in. I noticed my time machine backing up 15 GB of data which allegedly would have been added within two days. I could absolutely not trace this on my computer nor when I compared current folder contents with the most recent backup. Downloads, Apps., System are all excluded from my time-machine and couldn't represent such a dramatic data increase on my separate HD.

I'm doing an initial backup to a Time Capsule and I want to make sure all my data was copied successfully. Does Time Machine verify that the data was copied successfully or does it just send it and hope everything copied alright? I know this is the kind of question only the Apple developers would know for certain, but hey, sometimes folks on these forums are surprisingly knowledgeable so I figured I'd ask here.

Time machine failed in progress as my hard drive failed. I have an "in progress" file on my external harddrive that is about 160 GB. I would like to try and load this back onto a new harddrive. Migration assistant is not responsive nor does Time Machine recognize the external drive when connected.
Info:
iMac, Mac OS X (10.6.8)

I'm getting a new macbook. Currently I use time machine as a backup tool and was wondering if I should use it to transfer all my data to the new mac. One benefit of a new harddrive is the fresh install without all the junk that has built up over the years right? So wouldn't time machine just be transferring all the junk and stuff I want to the new mac? or is time machine smarter than this.

So I just successfully migrated all of my data and settings from my old iMac to my new 27 inch iMac using the Time machine backup on my Western Digital 1 TB external hard drive. Aside from the Time machine backup folder I also dragged a few other things over to the external hard drive because there was so much extra space on it. The drive is not partitioned.
So I'd like to start using Time machine with this new 27 inch iMac but the empty space that's left on the external hard drive is barely large enough to cover what I now have on the internal hard drive on my new 27 inch iMac. If I were to remove the Time machine backup from my old iMac there would be plenty of space again unless starting Time Machine on this new 27 inch iMac will just copy right over that backup file? Everything on this new iMac, the data and settings and so forth, is exactly the same. So is the user account. However the previous Mac was running Leopard while this new iMac is running Snow Leopard.
So if it doesn't copy over the old backup it will just create a new backup file? And if it does create a new backup file is there any point to keeping the old backup file since I no longer have the old iMac and wouldn't be able to access it again? Obviously if I didn't have to keep it I could erase it which would create plenty of extra space for me to start using Time machine again but with this new iMac.

We are a PC to Mac convert and still trying to understand some basics. We have an iMac 21.5 and expecting delivery of a external 1.5 TD drive. More than we'll even need, but dirt cheap. We also run Windows 7 64 bit through VMware Fusion. The only reason for that is the Windows version of Quicken is a better product the the Mac version.
We will back up pics, Videos, etc., on the iMac under MacOs with Time Machine. Can Time Machine also backup the quicken data files from the Windows 7 VM machine? I hoping we do not need to maintain separate backup drives to manage the different type of file formats between Windows and Mac. I hoping this can be managed through one place...Time Machine.

I recently purchased a Mercury Elite-AL Pro from OWC and it included Prosoft Engineering Data Backup. Are there advantages in using Time Machine vs. Prosoft Engineering Data Backup or vice versa? Also, what about something different like Carbon Copy Cloner? I'm looking to do this right the first time.

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 have a linksys wrt610n wireless router that isn't set up yet. You can attach USB drives to the router to use as a nas. I can't find if time machine will use it or let me use a drive attached to the router for my backups.

if i am running my new lion OS on drive #1 and i have a Raid1 array on drive #3 and #4 with all my DATA - can i back this up using Time Machine? i would like to place my OS's on a single drive and have my DATA in a raid array but if this means that i lose the ability to retain a Time Machine backup of my data i will simply upgrade to Lion and keep the data on this drive so it can continue to get backed up in time.

How long would it take to backup 900GB of data doing a full back-up using TimeMachine and my MacBook? My MacBook being a 2009 model with 2.13 GHz Intel Core 2 Duo and 4GB 800 MHz DDR2 SDRAM.
I have:
1 x MacBook 160GB drive
1 x Imoega minimax 500GB drive (firewire or USB 2 connection possible)
1 x Seagate 320GB drive (USB 2 only connection)
I have a 400 firewire port in my MacBook in addition to 2 USB sockets, as well as fireWire hub with power supply, should I wish to run 2 or more firewire devices at once, into the 400 firewire port.
My current backup drive is a Samsung USB2 1TB drive but for reasons that will hopefully become obvious below, I will need to purchase a new drive. I think a 1.5TB or 2TB would be fine and I guess a 400 firewire port is still better than USB2, even though it's only 400. However I'm not sure about the time issue.................

I have a Macbook Pro Late 2008 Model and have both my Iphone and iPad synced to it.I intend to save all my data from the macbook to a Time Machine and then sell my macbook as I intend to buy a new one this July.
1) would I be able to retrieve all my settings and data from the Time Machine to my new Macbook.
2) Would my iPhone and iPad Sync with the new macbook or would I need to set up a new sync ? I am hoping once I am able to retrieve all my settings and data from Time Machine to the New Macbook both my iPhone and iPad would be able to sync without requiring the need for a new sync setup .

MacBook Pro (15-inch Late 2008), Mac OS X (10.7.3)

Once I turn on the guest network in the Airport Utility, the network is unavailable and I can't connect to the Time Machine with the Airport Utility. I have to reset the device and keep it disabled. As long as the guest network is disabled, everything works fine. The Time Machine is fully updated and working fine otherwise. Any ideas?

Basically I have a 750GB hard drive in my Macbook Pro and over 300GB is taken up with 'BackUp' data. This is more than the total of everything I have on the drive other than that. Time Machine has always been setup on an external drive and when searching all files on the Macbook there is nothing for backup files so don't know where it is coming from.
Info:
MacBook Pro, OS X Mavericks (10.9.4)

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?

Stupid mistake, simple question. Was taking down some notes in TextEdit, closed file by mistake without saving. Anything I can do?
I should point out the file does exist, it just obviously reverted back to the state it was in before I did the particular hour or so of work in it.
EDIT: Should also point out I'm not using Time Machine.
