How can I back up a MacBook Air on a Mac Pro Hard Drive using Time Machine?
Want to back up a MacBook Air on a Mac Pro with a spare hard drive. Sharing allows Time Machine to find the hard drive, but get a drive busy message when time machine tries to back up onto the drive.
Any suggestions?
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message that corresponds to a failed backup. Now
CLEAR THE WORD "Starting" FROM THE TEXT FIELD
so that all messages are showning, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
If all you see are messages that contain the word "Starting," you didn't clear the text field.
If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Some personal information, such as the names of your files, may be included — anonymize before posting.

Every time I try to back up my Macbook Pro with an external hard drive using Time Machine, I receive the error of "the disk does not have enough space". I have a 500GB external hard drive and only 120GB Macbook. It worked fine before the latest Maverick's update. Any help would be greatly appreciated.
My guess would be it has created an entirely new backup of your drive when you upgraded to Mavericks.

How to backup external hard drive to another external hard drive using time machine ?
Hello,
i have an external hard drive which i store all my drum samples and sound library on and files are contantly changing, adding new sounds, deleting old ones etc ..
So my method of back up as of now is to just copy all the edited files and click and drag to the back up disk.
Now, my question is, how do i back up my external hard drive to another external hard drive using time machine ? I read somewhere that you can do this, i cant find the post however. It would be nice to automate the back up process rather than manually finding the files to copy over.
Thanks in advance !The question you pose is conditional, in that you should have more than an exact
capacity replacement for a clone, if the drive you are going from (or one going to)
has insufficient free space and that has a bootable clone on the drive; any space
tied up in a partition for Time Machine backup, takes away from the running space
if you should need to run the computer from a clone on the external HDD's other
partition.... Better to have a good capacity of additional reserve unused free space.
Be sure any clone copy that you hope to use as a re-close, that each in turn is tested
after a clone operation. Also consider using each running system's Disk utility and
have First Aid 'repair disk permissions'. Preparation of a new drive or even an old
drive that may have questionable artifacts or errors on it, should be reformatted. To
even go as far as Secure Erase (overwrite) at least one-pass before reformatting it
again, could help.
However, I'm not sure if the drives and situation you are looking at would necessarily
be a good match. It could work, but you'd need a reasonable size partition or hard
disk drive for a system. Snow Leopard and all its associated applications, can do
OK in a 100GB HDD. (My computers have more storage capacity than is used; so
for mine to have 60% free space, is good.) Virtual Memory is drive space used by
OS X, that can be a substantial amount for swap and temp files. Some applications
make duplicates of works-in-progress, for each change in an open file; that adds up.
{This question (& my reply) should've been in their own thread & not at the end
of one that is nearly three months old, + marked 'solved' by the original poster.}
So I guess I don't have a direct answer to your question; having just returned from
a few hundred miles and automobile issues, too. I'm not really thinking on-topic...
The clone should be on its own separate drive, and up to 3TB drive dedicated to
Time Machine may be overkill, however that software will consume old backups first
when it uses up all the space. Or usually that is what happens in TM backups. If
that isn't happening, there may an issue in how Time Machine is set up.
Good luck & happy computing! -
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. -
How do I restore a failed external hard drive using Time Machine?
I have an external hard drive connected to my iMac that is being backed up with Time Machine. I just realized that should it one day fail and no longer appear as a connected device, I'm not sure how to restore its data to another external drive. When I disconnected the external hard drive (to mimic a drive crash) and entered Time Machine to see if I could verify that the external hard drive was, in fact, being backed up - I didn't know where to find it. Under the Today (Now) information, I didn't expect to see it there as it was no longer connected to the machine. But when I went back a few days, I expected to see its backup appear in the Sidebar. But no!
So - how do I restore a failed external hard drive using Time Machine?
Searches for this information on Google yielded "iffy" results. I'm hoping someone here is able to offer some clear steps to follow. Perhaps I'm missing something silly. Thank you very much!I came across this discussion after encountering the same problem. Since my internal HD was cose to full I added an additional external HD to my setup. I moved my iPhoto files to an external HD and backed both this external HD and my internal HD up with Time Machine to another external HD. So far the theory. When I wanted to test if this setup worked I noticed that I could only see my iPhoto libraries on the external HD in Time Machine when the external HD was connected to my computer, but not if I turned it off. This led me to search for a solution on the Apple Support Communities discussion board.
The suggestions made Kappy seem right, at least in my experience, in that my Time Machine simply did not back up the external HD until I followed the steps he suggested above. These were the following:
"So, if you want it backed up then here's what you need to do:
1. In Time Machine preferences remove the external drive from the Exclude list.
2. Verify that it is now included with your other drive in the backup list.
3. Do a Backup Now to create a new backup of the external drive."
After doing this, my external HD showed up in the Backups.backupd as a seperate folder. I could clearly see the Time Machine back-up for my internal HD and my external HD. In addition, in Time Machine itself I was able to find the external harddrive by clicking on my own computers name under "Devices". I hope my experience helps to resolve your issue as this discussion board has helped me resolve mine (which I believe to be very similar).
Cheers! -

If time machine puts all of my photos onto my external hard drive using time machine, can I then delete the photos from my computer but view them again from the external hard drive? Basically, can I free up space on my mac but not lose years of photos?
To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
If the pictures are precious you should have at least two copies, and ideally another copy kept off site, -
I am backing up my computer to an external hard drive using Time Machine. It has been at 288.91 "used" for a while... should I just let it ride? It's been going for about 7 hours now
It does not immediately delete the files that are missing.. it merely tries to backup the new files it has discovered on the external drive. Since you moved the files there, the backup at least for a while will contain both copies.. and that is why it doesn't have enough space to backup.
Fixing the problem.. hmm pondini is the expert.. you should be able to delete the backup of the photos in existing backup.. there are instructions to do it.. but it is a very poor way to do things.
Much better. .archive off the existing backup.. this is long and slow but worth it. you need a usb drive of the same size as the TC drive. Then erase the TC and start a fresh set of backups.
The alternative is to use the USB drive as a new target.. but it is much slower than the TC internal drive.

How do I back up Wireless Hard Drive using Time Machine
I have a MacBook Pro and I'm running OSX Lion.
I'm having trouble setting up time machine to back up two USB external hard drives (named Portable iTunes and Portable iPhoto) connected to my Airport Extreme Base Station. I have a time capsule with a 3TB USB WD MyBook external hard drive that I'm using as the Time Machine Hard Drive.
Portable iTunes, Portable, iPhoto and MyBook are wirelessly mounted to my desktop.
Will someone please explain how I can set up MyBook to wirelessly back up the two portable drives using Time Machine?
Thanks in advance.
Wyatt.Will someone please explain how I can set up MyBook to wirelessly back up the two portable drives using Time Machine?
Sorry, but Time Machine can only backup a hard drive that is connected directly to your Mac using USB or Firewire. -
I want to create a back up of my iPhoto library on an external hard (not the time machine backup). I've searched the iPhoto help, but unfortunately it does not tell me 'how' to create this additional backup of my library. Thanks
Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store -

How can you tell which files have backed up to external hard drive using Time Machine?
Hello Mac Users,
I have Macbook Pro (early 2011) and recently purchased a WD My Passport for Mac external HD. I have completed a back up using Time Machine, however how do I tell what files actually were backed up? I have a ton of audio, documents and photos that I would like on there. Its a 2 TB HD, my memory is 750 GB... Im using 632. At end of back up, the drive still had 1.88 TB left. Any help would be appreciated! Thanks
Linz19This procedure is a diagnostic test. It makes no changes to your data.
Please triple-click anywhere in the line below on this page to select it:
tmutil compare | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take several minutes to run. Wait for a new line ending in a dollar sign ($) to appear below what you entered.
A TextEdit window will open with the output of the command. Don't post all the output; just read it yourself. Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
Files that you’ve excluded from backup, or that are excluded automatically, are ignored.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.
Caution: Under some conditions, tmutil may falsely flag files as not having been backed up when in fact they have been. It can be confused by multi-linked files, or by files with a modification date earlier than the one in the snapshot. This will not be an issue for most users. If the results of the above procedure surprise you, inspect your snapshots directly. -
