can i back up 2 macs on one external hard drive?
If the external drive is large enough, yes.
Recent versions of Time Machine will do this across a properly set up and Shared network connection or to a drive on a Server. But you may be unhappy with the amount of Wireless traffic generated to perform the backups, especially the initial full backup.
Utilities like Carbon Copy Cloner will do this ONLY when performing a file-by-file backup. A "Disk Image" backup reproduces the Source disk, including blank space, and fills the entire Destination drive with the Source Disk image.

I have my itunes on an external hard drive which I use on my macbook. Can I back these files up through time machine onto a second external hard drive?
For TM yes, for another backup program running on the mac yes. You can avoid the NTFS issue by installing a NTFS driver in your mac: there are two proven ones: Paragon and NTFS-3G. These drivers make it possible for a mac to read and write NTFS formatted drives.
But it will not help TM (I am not 100% sure about that), but other backup apps it will help. -
I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?
What I am ultimately wanting to do is make more room on my computer by backing up all of my files onto the external hard drive and then deleting them off of my computer. However, neededing to be able to retrieve them from the external hard drive later down the road.
From what I have read and am trying to understand, is that I probably shouldn't have used time machine. I need to use the external hard drive like a basic flash drive where I can put things on and get things off without having it automatically update through time machine everytime I connect it to my computer.
Not tech savvy at all and barely understand basics. I need very simple and easy to understand explanations.sydababy wrote:

BIG BIG MISTAKE ..... youre making a linchpin deathtrap for your data trying to shove everything on a single fragile HD.
Dont suffer the tragedy other people make, buy another or 2 more HD, theyre cheap as dust.
The number of people who have experienced terror by having a single external HD backup is enormous. One failure that WILL HAPPEN, and kaput,......all gone!
Dont do it, its all about redundancy, redundancy, redundancy.
follow here:
Methodology to protect your data. Backups vs. Archives. Long-term data protection
Deleting them off your computer is fine....having only ONE copy is extremely BAD.
The Tragedy that will be, the tragedy that never should be
Always presume correctly that your data is priceless and takes a very long time to create and often is irreplaceable. Always presume accurately that hard drives are extremely cheap, and you have no excuse not to have multiple redundant copies of your data copied on hard drives and squirreled away several places, lockboxes, safes, fireboxes, offsite and otherwise.
Hard drives aren't prone to failure…hard drives are guaranteed to fail (the very same is true of SSD). Hard drives dont die when aged, hard drives die at any age, and peak in death when young and slowly increase in risk as they age.
Never practice at any time for any reason the false premise and unreal sense of security in thinking your data is safe on any single external hard drive. This is never the case and has proven to be the single most common horrible tragedy of data loss that exists.
Many 100s of millions of hours of lost work and data are lost each year due to this single common false security. This is an unnatural disaster that can avoid by making all data redundant and then redundant again. If you let a $60 additional redundant hard drive and 3 hours of copying stand between you and years of work, then you've made a fundamental mistake countless 1000s of people each year have come to regret. -
My hard drive on my computer crashed! This is the computer my ipad was sync with! All my photos of my three girls are on the ipad, but how do I get them transferred to either an external hard drive or to another computer - or just have them all printed - nearly 1000 photos!
Also, can I back up my ipad with an external hard drive? If I try to sync to a new computer it will erase everything I currently have on the ipad , correct?
Thanks for your help - I am worried if I don't do something quick, my ipad will crash too!Right. You didn't read the post, you only read the title.
The title came from an earlier step in the process when I was posing a question to the systen.
The pertinent part of the question is "How to I back up documents that are stored in iCloud"
That the destination for the backup is NOT my internal HDD should be clear from the rest of the post.
And frankly, even if that is where I want to back up to, that would at least give me two copies, at least giving me one duplicate of the stuff on iCloud.
So please stop wasting my time if you can't answer the actual question: How do I backup content that is stored in iCloud. The destination of the backup is irrelevant.

After clean install of Snow Leopard, Time Machine did not restore all files. When I try to restore these files I get "Not enough disk space" error. What do I need to do to get these important files back onto my Mac from my external hard drive??

For what the Apple Store's charge you can buy almost buy a new computer.
Just for giggles I brought my old laptop in for a drive upgrade and asked, they wanted $600 for a drive that only cost $120 at the time and it was a slow 5,400 RPM drive. The new Mac's of a similar make were going for $1000.
I did the drive replacement myself, got a faster drive of better quality for $300 instead.
Then another time I asked for a RAM upgrade from 4GB to 8GB, they wanted to charge $400 + $35 for the labor.
The same RAM is on Crucial.com for $90 and all I need is a 00 micro phillips screwdriver.
So you see what's going on here.
I think what you should do, if your out of warranty/AppleCare, is to call up the local PC tech guy who also does Mac's and have them fix you right up.
They can offer more personalized care which you need. Clone your old drive to the new and everything.
With Apple they are overworked at the Genius Bar and just place roadblocks so you buy a new machine instead.
For instance, all new iMac's now have proprietary drive software installed on the hard drives for heat monitoring. So now the only choice a user has is to bring their iMac into a Apple Store for a very expensive drive upgrade, which a person then decides the money is better spent buying a new machine. -
Can i back up multiple macs to the same hard drive
can i back up multiple macs to the same hard drive
Yes, you simply share the drive to the network.. in whatever way that is possible as you have given us no info.. over the network TM will create sparsebundles.. locally it can produce a straight backup ..

How to use carbon copy cloner to back up two computer in one external hard drive
Hello,
I have only one external hard drive which is already used for backing up my old macbook. Recently, i bought a macbook air. Is it possible to use carbon copy cloner to backup my data from macbook air to same external hard drive? If yes, is there anything I should be caucious? If not, could you suggest any other software of other method to backup my macbook air? Thanks!!Yes, provided you have the space. You will need to create another partition on the drive to use as the backup volume for the new computer.
To resize the drive do the following:
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work. -
Can I add my iphone to an exising itunes account which is registered to my ipod without wiping my computer library? Also is it poss to back up my library onto a external hard drive instead of CDs?
"am I still able to register another phone to the same ID?"
Yes.
") that I do end up creating a new apple ID "
This will cause complications. i do not recommend this. -
so my iMac (10.5.8 its pretty old ) got stuck on the apple logo loading screen (as I call it lol) and it will not go beyond that .I've already made and appointment for the genius bar but now would I back up my files with an external hard drive ? No unfortunately I don't have any other laptop or computer just the external hard drive. how would I back it up? Does it have something to do with "target disc mode"?
Hi,
Thank you for great advice re SuperDuper.
You wasnt to know we didnt live in USA. We will try to get the full retail version of Leopard off the net. We will also phone round the apple resellers.
In the meantime, we are happy running Tiger with the knowledge that SuperDuper has cloned our hard drive in case of a disaster.
SuperDuper recommended backing up the hard drive with a new user account if we were using filevault on the master account. We backed up our hard drive without creating a new user with filevault as we could not read the pdf `Instuctions as preview was not responding.
Is this copy safe to use as a bootable drive or should we copy our entire HD again using a new user account without filevault?

Can a PC and a Mac read my external hard drive?
I just recently got a MacBook Pro. I have an external hard drive with all my pictures and music on it. I plugged this into my Mac and went to back it up with Time Machine, but it said it had to remove everything currently on the external since it was formatted to a PC. I made sure to save everything on there, went ahead with the back up, and put everything back on. Today, I tried to plug the external into my PC at work to take a look at some stuff and I wasn't able to open the external at all. I'm assuming this is becuase I reformatted it to the Mac. Is there any way to make it so I can use my external on both my work PC and my home MacBook? Thank you
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select the external hard drive (entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to MBR then click on the OK button. Set the format type to MSDOS (FAT.) Click on the Partition button and wait until the process has completed. -
I can't copy iTunes media files from one external hard drive to another.
Hi, I am running the latest iTunes and Mavericks software on my MacBook Pro. My iTunes library is stored on an external Seagate 2tb hard drive and it is almost full. I want to transfer the files to a WD Elements 3tb external hard drive and have made that new volume the destination folder for my iTunes library. However, even though I have enabled read/write on both volumes and made the iTunes media folders on both shared folders, I can't copy all the files from the Seagate drive to the WD drive. It comes up with an error message that says "The operation can't be completed because an unexpected error occurred (error code -8058)". I can transfer files from my MacBook hard drive to the new volume, but can't copy files from the old Seagate volume to my MacBook hard drive; it makes the "boing" sound that indicates it is copying but nothing transfers. Files that won't copy include all music files, some video files and all podcast files. Some transferred with no problem. Any ideas out there?
Hi Limnos, thanks very much for your reply.
both external drives came preformatted for Windows but I erased each and reformatted them for Mac before using them.
i made the destination folder on the new WD drive the new iTunes folder using Advanced preferences in iTunes.
my original iTunes folder on the first drive contained all my iTunes files, as that, also, was the destination folder that was linked via Advanced preferences.
If I download new content now with the new drive attached, iTunes has no trouble finding where to place the files.
in Preferences I have both boxes checked (copy files" and "organize") that deal with copying iTunes files.
When I first attempted to copy all iTunes files from one media folder to the other on the external drives, I just did a drag and drop of the whole iTunes media folder from one to the other while both were mounted on my desktop. It started copying immediately with no problems, but as it progressed it started skipping files, each time displaying the error message I reported earlier. that included my entire Music folder. When I open, for example, a season folder that contains files that would not copy, eg, Modern Family Season 5, the episodes that won't copy are there and visible but any attempt to drag and drop them into the correct folder on the new drive results in the error message. There is no pattern to it; it will choose some episodes from some seasons but not others, and no music at all.
when I look at the "missing" files in iTunes they have the small exclamation mark that indicates the file is missing, but when I locate it through iTunes it doesn't copy the file on the old external drive to the new one. It just plays it having found the file on the old drive.
originally I had to make the iTunes folder on the old drive into a shared folder using the Get info window after either a software upgrade or an OS upgrade (I can't remember which, it was several years ago). For some reason the upgrade changed the preferences of that folder to a Read Only folder and after researching the problem found the only way to keep using the drive was to make the folder a shared one. I can't remember why and I apologise for that but it was a long time ago.; I can tell you that at the time it was necessary.
thanks again for your time; I have a good working knowledge of iTunes and Macs in general so I truly believe I have done everything according to how it should be done,, but clearly I've done something wrong! -
Hello kind support people - I'm not hugely technical so would appreciate any advice, I'm very worried about my i-photos and loosing them. All my important documents are already on google drive so that's ok if anything has gone wrong. Does all the information stay on my mac (such as photos and mail etc) when I upgrade? Am I likely to experience any difficulties or should I be doing anything else? Yesterday I used time machine for the first time, I have an external hard drive with back-ups taking place all the time (completed yesterday over a couple of hours). Can I just eject the hardrive now and put my upgrade disc in?
Thanks in advance1. Yes, unless a problem occurs.
2. No, you’re not.
3. Yes.

Can't back up my iPhoto 08 my external hard drive
I have iPhoto 08 and have a USB 2 external hard drive connected to the new Airport Extreme Base Station. When I open up my photos folder and attempt to drag the iPhoto icon to my external drive on my MacBook Pro I get an error message stating that one of the photos file names is too long and can't be copied. Then my iPhoto does not back up after I hit the "okay" in the error message box (there are only two options, "cancel" and "okay".
What is the deal and is there a workaround?
Thanks!Once you've confirmed that the EHD is formatted correctly and all is well (run Disk Utility and repair the disk) try the following to create an almost "duplicate" library on the EHD:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.>Click on the Add Library button,
2 - select the library you want to add from those in the selection window.
3 - make sure that in the rebuild window the checkbox "Scavange orphaned photos" is checked.
4 - now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option
5 - in the next window name the new library and select the EHD as the location where you want it to be placed. Click on the Create button.
Note 1: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost.
Note 2: Your current library will be left untouched for further attempts at a fix if so desired. -
Can I back up ipod touch directly to external hard drive - bypass using computer?
I am trying to figure out if it is possible to back up my ipod touch to an external hard drive directly. I know it is possible connecting the external to the computer and doing the simple drag and drop but would rather just by pass connecting to the computer and use the ipod directly. If it is possible, any suggestions?
I am trying to figure out if it is possible to back up my ipod touch to an external hard drive directly.
it isn't.
but you can back up the "backup folder" to an external. you will find the location of it in this support article -> About Backups -
HT5182 How can I back up photos from iPhoto to external hard drive?
I have a large number of photos that I need to move onto an external hard drive to free up my MBP's internal hard drive. Most of my photos were imported in RAW format and editied in iPhoto. I understand from other posts that iPhoto converts these photos to jpegs. I'm quickly running out of room.
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
Regards
TD
