HT3275 time machine preparing back up

My time machine is stating "Preparing backup" for a very long time but it has not back up any information in 2 months. What can I do to get my time machine to back up again?

I had the same problem. Time machine would do a few backups successfully, but then it would continuously display "Preparing Backup". . .and would never progress to the backup itself. Even after a full day or more.
I found the answer buried here under another discussion of this seemingly frequent problem:
Open SYSTEM PREFERENCES. Go to HARDWARE/ENERGY SAVER.
UNCHECK the checkbox next to "Put the hard disk(s) to sleep when possible.
Having done this, my Time Machine backups run on time and correctly!

Time Machine "preparing back up"

My Macbook has recently decided to stop backing up on my Time Capsule. I can still access the internet wirelessly via the Time Capsule, but whenever the Macbook tries to start a backup, it gets stuck "preparing to backup".
I have an iMac that backs up on it perfectly OK on this Time Machine so I can only assume it's a problem with my Macbook. I have tried reconfirming the password in Time Machine preferences and restarting the Macbook, even trying an ethernet connection but no joy. When I connect via the ethernet cable, my internet connection stops. Is this a clue?

Apple support fixed it and seeing as no one here could help, I thought I'd post up my solution.
It seemed that my backup had been corrupted by a few too many stopped backups. Although you can stop Time Machine backups, doing so too frequently can cause problems like mine.
I deleted my backup on Time Machine [the sparse bundle] and re-indexed my Mac Book hard drive. I did a separate backup onto an external hard drive to be safe as I was without a backup at that point.
The Time Machine now begins to back up correctly.
My advice would be to always let the Time Machine do it's thing and avoid quitting back ups.
Hope this helps.

Time Machine prepares back ups of 10GB and more with very little activity on my computer

I have an early 2008 iMac with a Samsung 750GBHD, and I am using a Time Machine since 4 years ago working pretty well.
As of beginning 2014 it started to show many errors but at the end of the day there were 1 or 2 back ups done. During this August I realized that back ups were of a size of 10Gb and more nearly every day while the activity of the computer was very light, internet and mail. I cut an anti virus that was working on the background with no success. There is no virus activity, the comp is clean.
What could be the reason for this abnormal activity?

Only way to find out is to analyse what is actually causing the large backups.
Have you installed the widget yet??

Or you can get a software app that tells you what TM is doing since it is hardly forthcoming.

HT3275 Has anyone come across the red "i" message saying "The backup disk image "/Volumes/Chris...(the last bit being) iMac.sparsebundle" is already in use? This has prevented my time machine from backing up from this morning (5th Dec 2012).

Has anyone come across the red "i" message saying "The backup disk image "/Volumes/Chris...(the last bit being) iMac.sparsebundle" is already in use."?
As of yesterday (4th Dec 2012) everything was fine, no trouble or problems at all. Wake up this morning, turn on the computer and when it came time to backup itself, the message occurred above and this has prevented my time machine from backing up from this morning (5th Dec 2012) ever since then.
Everything on my computer is up-to-date but this problem still persists displaying this message practically every hour, on the hour and nothing is getting backedup!
If you know what is going on and more importantly, how to fix this, I would be indebted to you for sharing your knowledge with me on this subject.
Thank you.

Can I Use Time Machine To Back Up a FAT32 Disk Containing Image Files?

New iMac User Here. I just bought a brand new but mid-2010 27" i7 iMac. Although I've used recent MacBooks when traveling I've got no experience with Time Machine or other similar third party back up software.
I moved to the iMac from a desktop PC running Windows XP Pro SP3. I use the computer(s) mainly for photo image storage and processing. My workflow is based upon Adobe Lightroom (now v3.4.1) and I plan to stick with it. In the PC I had three internal hard drives, 2 of which were dedicated to image files. They were formatted as Windows NTFS. In preparation for the switch I formatted an external drive as FAT32 and copied all the image files to it. Now with the iMac I have Lightroom installed on its internal hard drive but keep the image files on the external hard drive and access them as needed. So far, so good.
The problem arose when I tried to set up Time Machine to back up both the internal hard drive and the external external drive. It will back up the former but not the latter. It tells me it does not interact with FAT32 disks.
Any thoughts, explanations and/or solutions for establishing a simple, single back up routine for both internal and external drives will be most appreciated.

Thanks very much for the quick response. You confirm my intial suspicion, but your suggestion relies on my memory to accomplish on a regular basis (not the best of solutions) and further would be an extended disk run every night because it would not just be backing up new additions but the whole large disk, right?

Time Machine - Preparing backup - It's endless

My C2D Mac Mini is hanging on Time Machine - Preparing Backup for the second time since "Upgrading" to 10.5.2
I had to re-format my backup disk last time and start all the backups again.
Here is an extract from the console log:
29/04/2008 23:50:13 /System/Library/CoreServices/backupd[1094] Starting standard backup
29/04/2008 23:50:13 /System/Library/CoreServices/backupd[1094] Backing up to: /Volumes/LaCie Disk/Backups.backupdb
29/04/2008 23:50:15 /System/Library/CoreServices/backupd[1094] Event store UUIDs don't match for volume: Macintosh HD

Does anyone recognise this? I'm a Mac novice so I don't understand what it all means. I hope I don't have to reformat and start again as I was converted to Mac from PC on the advice that "A Mac Works!"
My backup drive is a 500GB Lacie Mini if that is of any relevance. Spotlight is told not to index the drive and also the Lacie drive is told not to back itself up.
Can anyone help as it's driving me nuts!

Are Lacie really that bad? I thought that the main reason they are mentioned in these forums is that Lacie are one of the only brands of external storage that apple actively promote through their own web stores so there a good chance that quite a few Mac users will buy one. Anyway I can't afford to buy another Hard Drive at the moment and the lacie works perfectly apart from Time Machine.
The problem seems to be with Mac OS the more I delve into these forums and more importantly the 10.5.2. update which is where Time Machine appears to be providing users with a lot of troubles.
The Apple support self service on the website is far from comprehensive as I guess they want you to purchase Apple Care for ongoing support after the 90 days initial period but come on apple give us a break and sort it out or provide a support email address for specific problems!

Time Machine preparing lasts forever

When I start Time Machine to back up, it takes hours (last night it has been on), ad is still preparing, how long can I expact it to last before preparations are finished.
It's been a while since my last back up (because of this problem).
I back Up to a LaCie 1 terra disk Firewire.
Actually I want t erase the disk, and start it all over, but it is not possible to deactivate this disk, how can I erase the disk.
Thanx

I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was? I want to make sure I will still have various important files on my new computer, like my songs in iTunes, my photos in iPhoto, etc, etc. Thanks so much in advance!

Welcome to the Apple Support Communities
When you turn on the new iMac for the first time, Setup Assistant will ask you to restore a backup, so connect the external disk and follow steps to restore all your files to your new iMac. Your new Mac will have the same settings and programs as your old computer.
In other cases, I would recommend to restore the whole backup without using Migration Assistant or Setup Assistant, but a Late 2012 iMac uses a special OS X build, so the OS X version that you're using on your old Mac won't work on the new one.

I have been storing my Aperture and IMovie Libraries on an external hard drive that recently died. Fortunately I've been using Time Machine to back up to a 2nd external drive. How do I restore my libraries to a new external hard drive?

I have been storing my Aperture and IMovie Libraries on an external hard drive that recently died. Fortunately I've been using Time Machine to back up to a 2nd external drive. How do I restore my libraries to a new external hard drive?

This is a tricky one.
Open up Time Machine and go back to a date using the timeline on the right side of the window when you know the drive was working and was backing up as part of Time Machine backups.
Click on the name of your Mac under the Devices heading on the left side of the window in Time Machine, and if things are working correctly you will see Macintosh HD (or whatever you have named it) and the name of the external hard drive that was backing up in the past.
Right-Click on the name of the external hard drive and then click on "Restore (name of drive) to....." You may be asked for your adminstrator password at this point.
It might be easier to restore the drive contents to your desktop if you have room on your Mac, and then copy things over to the new external drive where you want to store the Aperture and iMovie Libraries.
Once the libraries have been moved over the new external hard drive, you will likely need to "point" Aperture and iMovie to the location of the libraries on the new external hard drive.

Having trouble getting Time Machine to back up my external hard drive. Any suggestions?

I'm running Mountain Lion on my iMac and I've been using Time Machine to back it up to my Time Capsule. Recently, the iMac's hard drive filled up, so I moved my iTunes library to a new Airport Time Capsule. But I can't seem to get Time Machine to include the new Airport Time Capsule in its back up.
The only suggestion I can find is to make sure it's not excluded in the Time Machine options, and I can see that nothing is excluded. However, when I go into Time Machine, the Airport Time Capsule is greyed out in the Finder window.
Anyone have any ideas? Thanks in advance, I'm a little nervous about having my iTunes library hanging out there without a back up...

You can't back up the internal drive of the Time Capsule with Time Machine. It will only back up locally attached storage devices, not network devices. There's no way around it. You may be able to back up the TC with third-party software such as "Carbon Copy Cloner," but it will be very slow. The internal drive of the TC is only suitable for use as a backup device. It's not suited for storing original data.
yeah well you can use the external hard drive as a data extension to the time capsule internal hard drive. like a RAID in effect...

I would like to use time Machine to back up to a network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it

I currently have a mini server (OSX10.8.5, server 2.2.2) that I am using Time Machine to back up 4 external drives that are connected to the server via firewire 800. I would like to use Time Machine to back up to a windows network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it for use.
Can this be done
Thanks for any and all help

The supported targets for Time Machine backups are local (direct-connected) disks, and network targets include Time Capsule, a disk hanging off the current-generation AirPort (though not earlier AirPort devices), and OS X Server systems.
The Time Machine storage is based on the HFS+ file system, so I would not expect TM to work with SMB file services.
While there are hacks to allow Time Machine to access network drives, I would not consider those to be reliable. Skim the forum and the 'net for related details, and for previous discussions of setting this up and the related issues that can arise.
Remember to test the recovery with whatever you decide to use; whole point of backups is the ability to restore the data, after all.

I can not get Time Machine to back up an external WD Passport 2 TB drive! Has anyone else had this problem? The drive is new and I was running Snow Leopard and upgraded to Lion and it still won't do it. Time Machine backs up the internal drive fine.

I bought 2 2TB WD Passport Drives with the intention of housing my iTunes/iPhoto libraries off my older MacBook. I have successfully transferred the Libraries to one and am using the other one for Time Machine. In Snow Leopard I could back up my computer to Time Machine no problem but when I did not exclude the iTunes/iPhoto drive the back up fails. Both drives have been reformatted, permissions repaired and checked in Disk Utility and one was replaced. I have been to the Genius Bar now 5 times. I have tried using USB drive and FireWire. Both drives are recognized and are working properly otherwise regardless how they are connected. Finally yesterday the Apple store installed Lion to see if that fixed the issue and it did not. Time Machine successfully backed up a USB Flash drive, and today I will try an older external drive. Any ideas on what else to try??? Do I have to resort to third party software like Carbon Copy Cloned to get this done? Any ideas why this wont work? I am using a FireWire converter but as I said, both drives are working normally otherwise (libraries working, time machine working for the computer's hard drive. Any ideas would be appreciated!!?

Thanks so much but none of that helped. It was driving me crazy because it would back up another external drive. I just changed the name of the drive from iPhoto/iTunes Library to Media Libraries and IT WORKED!! I guess for some reason it didn't like the drive being called iPhoto or iTunes ???? I don't understand but I have tried so many solutions and exchanging things out but the name change did it????!!!
Thank you for your help and replying to this. Guess I made my own issue!

Using Time Machine to back up an external hard drive dedicated to Adobe Lightroom 5

I recently began to use Adobe Lightroom 5 (I continue to use Aperture, as I have for years). All of the Lightroom image files and catalogs are on one external hard drive, which I use on my iMac, my Macbook Pro, and in the digital labs of a school where I'm taking a course.
Not yet having developed a protocoI for creating a back up of all my Lightroom image files and catalogs that I could use in the event of my Lightroom-dedicated drive's failure, I have just done a drag and drop of the whole drive's contents to another external drive (which, as it happens, I have been using for some time for my Aperture vaults).
I am thinking of removing the dedicated Lightroom drive from the excluded list of my iMac's Time Machine (which uses yet another external drive), so that I can easily and automatically create back ups of changes to the Lightroom external drive without having to do the cumberome and inelegant drag and drop at some yet-to-be-determined frequency. (The Macbook Pro uses a Time Capsule for its Time Machine; I envision using only the iMac's TM external drive for Lightroom backups.)
What is the simplest and most desirable way to actually execute the backup? I envision that it would be this: that every time I want to do a Lightroom back up, I'd mount the Lightroom external drive on the iMac (or keep it mounted if my work session has just been on the iMac) and then ask Time Machine to "Back Up Now." When the backup is finished, I'd dismount the dedicated Lightroom drive.
A related question is what if anything would be the effect on my Lightroom work if a Time Machine back up began while I was working in Lightroom? Or if for some reason an hourly TM back up began and I needed to quickly end a Lightroom session before the backup was completed?

Mac Basics: Time Machine backs up your Mac

Why am I unable to connect to my airport whenever I put my computer to sleep while the time machine is backing up?

Ever since I installed Lion (version 10.7), I am unable to reconnected to my Time Capsule and get on the internet after I put my computer to sleep and then wake it back up. This doesn't happen all the time -- just when I put my computer to sleep when Time Machine is backing up. If I put my computer to sleep when it's not backing up, it's fine. If it is backing up though, when I wake my computer up again, it is unable to reconnect to the Time Capsule to allow me to use the internet. I have to wake the machine up, click on "Stop Backing Up", wait 30-60 seconds, click "Turn Wi-fi off", wait another 30 seconds, turn it back on and then I am fine. If I just turn wifi off and on without stopping the backup, it doesn't work and I am still unable to connect to the internet. I currently have 10.7.1 but it still has the same bug. 10.6.x did not have this bug. Other than "don't put your computer to sleep when Time Machine is backing up," any suggestions? Any help would be greatly appreciated!

In this case, that hint may help.
According to Apple support, some configuration files may get damaged or corrupt by time, after updates or upgrades and should get deleted ocasionally.
OK ... switch off wifi on the machine.
Then go on and delete the files mentioned below.
You will find the files on your system drive (not your home folder) as follow:
/library/preferences/com.apple.preferences.accounts.plist
/library/preferences/com.apple.preferences.sharing.plist
/library/preferences/SstemConfiguration/preferences.plist
/library/preferences/SstemConfiguration/com.apple.airport.preferences.plist
If there are files in this folders with the same name but additional .orig at the end, delete them too.
It is possible that not all files are on your system. That will be ok.
The files will get newly created by system on reboot.
For that reboot the machine.
Join your wireless again.
If you are using Lion, the Library is hidden. You have to use (menu bar) "go to" -> "go to folder" on finder to access them.
If the problem (unlikely) persists, report back here.

My Macbook won't start, and I must reinstall the disk. I haven't used time machine to back up, and I want to use an external drive to back up now. How can i do this from the utilities page?

I am currently in Zambia on missions work and my computer is constantly exposed to heat. I have just been trying to avoid using it during the hottest part of the day. Today though, I started it up and it was stuck on the grey page with the rotating circle for over an hour, then once the circle left, it remained frozen on the gray page. I used command + r at startup to go to the utilities page to analyze the disk. It found that there were problems with the disk, but then it could not fix those problems and told me to backup as much information as I could and reinstall or redo it all. I haven't ever used time machine to back up any of my information, but i have an external drive that I can use right now to backup my files. I can't get into my computer though to backup the files. How can I use this external drive to backup my files while the computer is currently messed up? Please help.

Emergency Backups (Data Recovery)
A)          Format an external disk:
          (This will erase all data on the external disk.)
          Boot in recovery mode (power then Command-R).
                    Alternative: Network recovery boot (power then Command-Option-R keys)
          To format (and erase) the destination recovery disk:
          Plug in the drive you are about to erase.
          Select the volume that is NOT your system disk.
          Click on Partition.
          Pull down under Partition Layout to 1 Partition.
          Click on Options…
          Select GUID Partition Table.
          Name: Emergency Backup (or whatever you prefer)
          Format: Select Mac OS Extended (journaled)
          Click Apply.
          Click Partition.
B)          Try to boot in Safe Mode (power then Shift key).
          (This will be a slow boot. Be patient.)
          If it won’t boot in Safe Mode, jump to C.
          If it boots in Safe Mode, try to boot in normal mode.
                    If that fixed your problem then start a Time Machine backup.

                    https://discussions.apple.com/docs/DOC-4055
          If not, boot in Safe Mode again.
          Go > Computer.
          Double click on the system disk.
          Drag the Users folder to the recovery disk.
C)          To clone the disk:
          Boot in recovery mode.
          Select Disk Utility.
          Try to repair the system disk twice.
          Whether or not the repair succeeds:
          Drag and drop the system disk to Source:
          Drag an drop Emergency Backup to Destination:
          (Take care not to reverse this order.)
          Click Restore (the lower Restore button).
Once your system is healthy, maintain two reasonably current backups. (Time machine restores can fail.)
Create either two Time Machine backups (good) or one or more Time Machine backup(s) and one or more bootable-clone backup(s) (better).
          Use Carbon Copy Cloner or SuperDuper! to create bootable-clone recovery disks.
