Applications :: Cant I Backup Multiple Days Without Using The Same Size Of Backup?
Feb 1, 2009
i am having a minor problem with TM
i use 1 external tb to back up everything
i back up about 725 gb if stuff and when i go to run my TM it tells me i only have 150 or so GB of space to back up the aforementioned 725gb.
Maybe i misunderstood TM, but cant i back up multiple days without using the same size of backup? i.e. i back up january 1st, december 1st and november 1st and it wont need 2.175 TB of space?

I've just starting using Carbon Copy Cloner, and I'm running my first initial backup right now, and it's causing freezes everywhere on my Mac. Everything is extremely slow, and every application seems to freeze. Is this normal or is something wrong? I just want to know to make sure I'm not doing something incorrectly.

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 searched but I can't seem to find an answer to this question...
I have 4 x 500MB drives in my Mac Pro and 4 x 500MB external firewire drives.
Currently I use Carbon Copy Cloner to clone each internal drive to it's respective backup. ie Drive 1 > Backup 1, Drive 2 > Backup 2 etc
Is it possible to use Timemachine in a similar way? so that each internal drive has it's own corresponding Timemachine backup?

I work for a media company, we hire out our stock of macs to clients and they often come back full of unwanted files and applications, we want to create a single backup on our network that we can automatically sync our macs to when they come back from a job, so it gets rid of all the extra files and resets back to just being the software we want. Then when software updates come out we can just update the 1 backup and it will sync to all the macs. Is this possible?

How big is a TM backup - is it the same size as the source?

I've recently re-jigged my system and upgraded to Snow Leopard. I've manually restored everything I want from a Time Machine back-up and am now back in business on my main drive. However, I now want to re-enable Time Machine but I'm having some problems; every time I back-up the total size is the same! I've excluded all the things I don't want, such as system-files, applications folder, developer folder, virtual machines folder, and a folder I use for large downloads (so they're not backing up at different stages). Every time though the total back-up size is calculated as the total data on my drive, minus the things I've excluded, and it crawls along at only a few kilobytes to a megabyte or so per-second!
For a volume with just under a terabyte of data that's an awful long time. This doesn't seem right though, as it means that my back-up volume is just going to full up after a couple of back-ups are taken, which is unacceptable. Anyone know what can be done about this? Both the internal and external volume are Journaled HFS+, my only though really is that the back-up drive already has Time Machine files on it, indeed the biggest portion of my files (about 850gb) is already on the drive in the exact-same folder structure as I'm using now, so those files shouldn't even need to be backed up!

I just bought an external hard drive and am using it to back-up my MacBook Pro with Time Machine. Both my MBP hard drive and external hard drive are 500 GB, but I noticed that my MBP HD has 85 GB of files on it while my back-up HD only has about 70 GB. I just want to make sure all of my files are backed up properly.

I haven't backed up my macbook in a couple days since I've been out of town and did not have access to my external hard drive. A little while ago I plugged in the hard drive and told time machine to do a backup. The backup started at around 24GB, which I thought was weird because I didn't change that much. An hour or so later it is still climbing and is at 77.1GB. By the time I finish typing this it will probably be even larger. The weird thing is it says 77.1 of 77.1 but then both numbers just keep simultaneously growing. I'm using a Seagate Desk and bucking up and aluminum unibody macbook running 10.58.

First off, I have an iBook G4 with Leopard, and an iMac Intel that I just recently upgraded to Leopard. I have used my external drive to previously backup my iBook with Time Machine. I would like to start backing up my iMac too, with the same drive. Would this present a conflict as far as the multiple backups from different systems on the same drive? Obviuosly space would be an issue in the long run...250GB drive, devoted only to backups. Also, if/when I utilize Boot Camp on my iMac, will the Windows partition backup through Time Machine?

have all of my music/videos on an external Maxtor 750 GB USB drive. I have all of my photos on the 750 GB internal drive of my iMac.
I want to get a 2 TB external for BU purposes.
Can I set time machine to BU both 750 GB drives on the 2 TB drive?

I will now have four MacBook Airs in my house (me, my wife, two kids) and would like to setup a SIMPLE way to back up all of them to a networked drive that I could connect to my Airport Extreme. Having read the horror stories about the Time Machine, I'm looking for a different solution if it's out there. Since both my kids and my wife are not too tech savy when it comes to this, I'd like something as simple as a networked drive where I can direct Time Machine to perform it's backups from each of their computers.
Is there a good solution that's close to plug and play to do this? I've looked at some different NAS drives online, but each seem to have different quirks to their setup.

I'm looking for an app that will allow me to specify which folders I want to copy to my external drive, updating existing files within it and copying new ones.
I don't want to backup settings, my whole harddrive nor make a bootable backup. Just something to backup what I want to backup and where.
Not sure if Time Machine can do that, but it wants me to reformat my external before I can even find out..and considering how much is on there, I really don't want to have to remove that all elsewhere while doing so. [Don't think I could anyway, none of my internal drives have that much space.]
So, does anyone know of a relatively painless backup app that could do simply what I want? Doesn't sound all that complicated in comparison to some of the more convoluted backup apps I keep finding.

Lately it seems that Time Machine has been underestimating the size of each backup. What it originally says to be a 10 MB backup turns out to be several GB. As it's backing up, Time Machine will say "X out of 10MB backed up" or something along those lines, but when X reaches 10MB, X continues to grow and so does the original estimate of 10MB. It might then say "13MB of 13MB backed up" and it will continue on this way until it has backed up so much underestimated data that Time Machine tells me it can't finish the backup because it doesn't have enough space on the backup drive. (Time Machine should've deleted some backups beforehand to make space for the new backup, but it didn't know to because it had underestimated the amount of space necessary for the backup.)
I have already wiped the backup drive and deleted all the Time Machine preference files, only to still face the same problem. I'm backing up my internal 1TB drive (only 300 GB used) and my 500GB external drive (400GB used) to another 1TB external drive, so having enough space on the backup drive shouldn't be the problem, right? BTW, I'm running Snow Leopard.

Here is what I want to achieve: I have my MBP with a 500GB hard drive that I want backed up to an external 750GB drive (A). Then I have an external 1TB drive (B) that I also wanted backed up to an external 1TB drive (C).
Or:
Internal -> drive A
Drive B -> drive C
Can Time Machine do this all for me or am I going to need a 3rd-party app to help. I know I can easily use TM for doing one of the backups, but will it handle both? If not, what's a good 3rd-party app that will help me accomplish this?

If I don't want to restore content from my backup with old Apple IDs (wife's old deactivated account, brother's account, etc), how do I remove that content from a backup? I skip in the restore process, but that doesn't seem to remove anything. I'm assuming the content/media from the other accounts isn't loaded.
I guess I'm looking to create a fresh backup with only the iTunes items associated with my account. I can't find a way to identify what media is from these other accounts in iTunes, so I keep getting this issue when I restore from a backup.

I have been using time capsule for only a few weeks and I have noticed that the file it has created "Elliot Newman's MacBook Pro_001b63936847.sparsebundle" only reads a file size of 95GB, when the disk I am backing up has 148GB used. Does this mean the backup doesn't contain all my files? I have to say it concerns me a little that the backup shows only a single file, is there anyway to see the files that time capsule has backed up? I am updating my MacBook soon with a bigger internal drive and I want to make sure all my files are backed up before I do this.

I have 2 Macs in the house, with a 3rd coming soon. I backup mine to an external hard drive using Time Machine, but neither of the others have a backup plan in place.
One user doesn't really need a robust backup solution, but the person getting a mac soon does.
I was thinking I could kill two birds with one stone if I got a Time Capsule. Now I've read all about how you can partition Time Capsule and stuff like that (and I'm technical enough that I could probably pull that off if I wanted to, but I don't think I do). What I haven't found out is what the Time Capsule does if two users have been syncing to it, and on the next backup it runs out of space.

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 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.
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.

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.
