OS X Technologies :: How To Disable Time Machine's Post-Backup Thinning

Apr 15, 2012

One of my Time Machine backup disks is huge – 3TB – and isn't even close to full. (I run a backup on that disk only a couple of times a month.) Nonetheless, after TM finishes a backup it does a "post-backup thinning" operation and deletes some "expired" backups. Clearly, this thinning is not needed to save space, as the drive has almost 2TB of free space.  I don't want it to remove those backups, yet, because someday I might want to recover a file from that particular backup. How do I configure TM so that it will not do any post-backup thinning?  I don't see any options via tmutil and I'm hopeful that someone might know little-known 'defaults write' sort of trick. I use OSX 10.7.3 Lion, and my TM disks are external USB hard drives.

OS X Technologies :: Time Machine Partition And Cloned Offsite Backup

Jun 18, 2012

I am new to mac and I am exploring my back up options.I have a macbook pro running OS X 10.7.4 - Lion.It has a 750 GB internal hardrive.I have some data that I require to be online all the time i.e. on the internal hardrive (say 500GB) and additional data that can be on an external hardrive and accesed when needed (say another 500GB).I would like to back up all my data and also have an additional offsite back up.Is the following possible / a good idea, and how would I execute it: 2 Large external hard drives:With 2 Partitions - the first partician for time machine and the second for my offline data, these could be 1TB each for example.I would plug this in regularly to back up my macbook and if I needed to access the offline data.Another 1 TB drive that is a complete clone of the first. I would use this once a week to create the clone and then store offsite.

OS X V10.7 Lion :: Using Time Machine To Determine When I Installed Update?

Feb 22, 2012

Does anyone know if there is a file I can look at on the system to determine what version of the OS is install?  I'm no longer able to boot once I updated to 10.7.3 and I want to restore from Time Machine back to 10.7.2 but I don't remember the exact date that I did the update.  I want to be able to look at the Time Machine backup files by attaching it to another machine in order to determine when I did the update and restore from that point.

Applications :: Time Machine Taking Long Time To Backup - Changing Backup Time?

Dec 11, 2009

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.

Software :: Time Machine Unable To Perform Backup / Backup Is Too Large For Backup Volume

Oct 26, 2008

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?

OS X Technologies :: Determine If User Is Using Virtual Display?

May 21, 2012

I'd like a Terminal or AppleScript command to determine if a logged in user is using a virtual display. 

The scenario is: user1 is in front of the local computer using user1 account (owns /dev/console); user2 is using using a virtual display for the local computer via ScreenSharing on a remote computer. 

I know `stat -f%Su /dev/console` will give me who is in front of the local computer, but I need another command to determine if user2 is using a virtual display on the same local computer.

Software :: Unable To Backup Via Time Machine / Backup Disk Image Could Not Be Created

May 1, 2008

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?

OS X V10.6 Snow Leopard :: Time Machine Backup Freezes On Initial Backup Attempt?

Mar 20, 2012

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.   

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.   

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. 

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.

MacBook Air :: Time Machine Backup Takes Up To 6 Hours To Do A Backup Of About 30GB?

Jan 9, 2010

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.

OS X :: Using Time Machine Restoring On New HDD - Time Machine To Recognize The Backup

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.

OS X :: Time Machine Backup After HD Replacement / Redundent Backup Going Take Up Space

Jan 11, 2011

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?

OS X :: Time Machine Not Working / Backup Is Too Large For The Backup Volume

May 23, 2009

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???

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. 

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.

MacBook :: Backup Management / How To Update Time Machine Backup On Different Mac

Jun 30, 2014

There are 3 macs:

A: an old macbook (the white one)
B: a modern macbook pro (retina)
C: another modern macbook pro (TBD) 

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.

OS X Technologies :: How To Delete Range Of Time Machine Backups

Feb 6, 2012

Is there a way to delete a range of time machine backups, say all dates from the first backup to 1/10/2012 (as an example).I know how to delete a single backup for a given date/time through the TM interface, however, deleting them one-at-a-time is rather laborious and time consuming if I wanted to delete a large number of them to free up space. Is there a way to select a "range" to delete, or am I stuck doing it one backup at a time?

OS X Technologies :: Time Machine Just 'stops' Copying Data

Jun 12, 2012

I have Time Machine set up to backup my laptop, and it works just fine. I then decided, having enough space to spare, to point Time Machine of my girlfriend's laptop to the same backup location (she had been backing up to an external drive).

After setting everything up (network location, password, and everything), Time Machine happily starts backing up: Until it just stops copying/transferring data. 

I start with a fresh, new, clean backup and I get no error message of any kind; after Time Machine selected the files to back up (= first run, so everything gets selected; that's about 40gb) it starts copying everything. But then it just stops. No errors, no progress, no anything.

This usually happens after having copied between 1 and 3 gb (I tried multiple times). Being on a gigabit ethernet, the copying is pretty fast; the first gb takes minutes. I even proceeded to letting the laptop run its backup through the night; even after a dozen hours, the indicator still is stuck at "1.27 gb of 40.24 gb" (or whatever). 

I went so far as to check the laptop's hard drive (no errors). The backup system appears to work just fine; after all, Time Machine starts the backup just fine and doesn't report any errors or issues. (Also, if there was something wrong with it, it shouldn't work with my own laptop, either.) The only difference I could think of is that my laptop runs Lion, while my girlfriend's still runs Snow Leopard (both to their respective newest versions; could this discrepancy be the cause of any incompatibilities?).

Every time I back up to my external drive Time Machine automatically backs up the whole hard drive which is very time consuming. This happens every time I back up.

I have used Time Machine to backup my data on an external hard drive with ample space for the past year. However, for the past month or so when plug in my hard drive and try to back up my files using Time Machine, it completely freezes my computer, to the point where I need to hold down the power button for 10+ seconds and completely restart. At first I thought this might be due to not enough RAM, but discovered it does this even if all other programs are closed.

Is it possible to have time machine backup all information on the 500gb drive to the time capsule, so encase the external drive takes a dump, I don't loose my entire music library? Maybe time machine is already doing this, I am not sure.
