Partitioning, Disk Utility, Time Machine

I attempted to use Boot Camp Assistant to allow me to install Windows. During the partitioning process, I got a message that instructed me to restart my computer... during the partitioning process! So I did, because I didn't think my Mac would instruct me to do something that would hurt it. Well, it did. All of a sudden I'm still not using Boot Camp, but my HD is severely shrunken! Is there a way I can "undo" what I possibly did?
Further, I tried to verify my HD and that failed as well. Following is the sequence of messages that DU gave me:
+Invalid volume free block count+
+(It should be 9957181 instead of 4558289)+
+The volume Macintosh HD needs to be repaired.+
+Error: Filesystem verify or repair failed.+
I use Time Machine to periodically back up my HD, and actually just did. If I restore my HD, how do I use TM to get my computer back to just how it was?

Disk Utility - Time Machine & iCloud

I don't understand why Disk Utility doesn't automatically run Verify & Repair after a resizing a disc partition. This simple failure on my part (unGENIUSness) lead to additional failures on when I tried to run TIME MACHINE. Time Machine never stopped running and never once created a successful disc image. I've seen other posts about this and it seems to be a very common failure. If Disk Utility doesn't run Verify then Time Machine should have. I can see this being an issue in iCloud too - not on Apple's Server end, but on the backup - if their is a formatting or disc error on the target device. Time will tell.

I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files?

HDD is a Toshiba 1TB, partitioned into two 500GB partitions.

Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.
Now
Have you tried to repair the disk yet

Restore to different disk from Time Machine backup

Using Snow Leopard. I installed a larger hard disk in my Macbook Pro just over a week ago, and kept the old disk. Time Machine had worked before the update and continued to work after the update. So I did another week of work and created new documents, etc. hopefully all backed up.
Then the new larger hard disk crashed, so I had to revert to my old disk which still had the old data on it. The old disk was named xxx180 and the new disk large disk xxx500. The user name and account name were the same on both.
With the old disk now back, if I look into Time Machine, I can only see backups containing data from dates previous to the upgrade, but all of those files are already on my disk. The later dates are there in time machine, but they have no files.
I have tried migration assistant, but it says that I can't have 2 user accounts with the same name - I don't want to re-create the account, just restore a few files.
I have booted from the Snow Leopeard disk and gone into Disk Utility to 'restore from Time Machine', but it says that the large disk information is 475 GB and will not fit onto the old small disk. I know that I only added a few documents and that they shoud fit on the spare space on the old small disk. The difference is only a few days of important text documents.
Can I see the backup files on the Time Machine disk other than through the Time Machine application?

Restore one hard disk from Time Machine backup

Is it possible to restore only one disk from Time machine backup? I have a SSD with OSX 10.8.5 on it while user folders are on a separate 4TB hard drive. I also have a Time Machine volume for backups. Yesterday the user drive failed beyond repair, but fortunatly I do have a recent backup. When I tried to resotre following insructions provided in the Time Machine manual, it does not give me an option to resore a specific disk from the backup, and tries to resotre only the System disk backup, in this case the SSD. Is there a way to restore a disk on which no system is installed?

Remote disk and time machine?

i have my external hard drive attached to my airport extreme and all my computers, mac and windows, play nice and can copy files to and from it but i have partitioned the hard drive to allow for space for time machine to work but time machine wont find it or if it does refuses to use it as a disk. does time machine work with remote disks?

heay,
I had the same issue with an exteral 250Gb USD WD disk....
I found the solution to my issue in the following manner.
1) the disk/partition must be formated "OS X extended" format.
2) you should be able to use you the Disk/Partition with TM while connected directly to the MAC. (this is just to make sure TM works fine.
3) connect the disk to the airport extreme via USB.
4) mount the the disk on the desktop
5) go to TM preferences and change the backup disk to the disk/partition you just mounted.
6) Activate the TM "status info" in the menu bar
7) turn TM "ON" (DO NOT ATTEMPT TO RUN TM, or you'll have to do the entire procedure from scratch)
8) close the TM preferences.
9) unmount the disk from your desktop (use the the eject button on the shared devices tap in the finder)
10) restart the MAC (you don't need to do this... but this is just to make sure that the disk is unmounted completely)
11) once the boot-up is completed, go to the TM status icon and choose "backup now"
You must make sure that the disk and or partitions you want to use with TM are never mounted before or during the TM process.
As long as the disk/partition is mounted TM will not function.
if you need to use the disk for other purposes than TM wait until TM has done its first run... then you can mount and unmount freely... TM is very sensitive to this "mount" issue.
Note that sometimes TM will fail to funtion... this is not a big problem...
you just need to make sure the disk/partition is unmounted and then run the TM back from the menu bar.
Also note that your first backup will most likely take a very very very very very long time to be completed. just leave the MAC on a make sure it does not fall sleep.
try the above and the let me know if it works or not...

Restoring disk from Time Machine

Hello!
I wiped my disk clean, rebooted using Snow Leopard DVD as a start up disk, and then attempted to restore my disk from my Time Machine backup. Everything seemed to flow just fine... UNTIL the "Transferring Information" window displayed "Transferring your Applications folder...". The blue progress bar has been stuck in the same place for 15 HOURS!!!!! The status still reads "Transferring your Applications folder...". Any insights into HOW I CAN MOVE FROM WHERE I AM TO SUCCESSFULLY RESTORING MY DISK FROM TIME MACHINE, IN A TIME-EFFECTIVE MANNER?
Oh man, I know someone out there can help! I really appreciate anything you can offer in advance! Thank you!
All the best,
NRM

Did Disk Utility find any errors on your TM drive?
No errors.
"*The Mac OS X installation couldn't be completed.* / If you continue having a problem installing Mac OS X, the installation log may help you diagnose the problem. To save the log, click Save Log. / To start installing Mac OS X again, click Restart. / To start up your computer using a different disc, choose Startup Disk from the Utilities menu."
There is also a window that is titled "Installer log" will 248 lines that I do not know how to read. Many have phrases like "ReportCrash [179]".
So it didn't get as far as it did the first time? You may have a bad or damaged SL disc, or a problem reading it. See if you can clean the disc.
No it didn't. I tried to clean the disc. I have restarted, and retried, four times now, and continue to get the same message.
If you're anywhere near an Apple Store or Authorized Apple repair location, make an appointment and take your Mac, the disc, and your TM drive. See if they have another disc they'll let you use to see if you can get any farther.
Is this a Genius Bar appointment you're referring to?
One line, early on in the report, that jumped out to me, is "You can't save the file 'Autosave Information' because the volume 'Mac OS X Install DVD' is read only."
Yes, that is a bit irritating, isn't it? I don't know what good it is.
Well, I guess we all did our best. If there's anyone out there with any new insights, I'd love to hear 'em!!!
Again, big thanks to everyone!!!

Can two macs use same disk for Time Machine backup with Airport Extreme?

Hi
I use a Western Digital disk as a wireless Time Machine backup connected to the USB port on my Airport Extreme and it works great. My question is: can my girlfriend use that same disk for Time Machine backup from HER computer too? (I don't mind formatting the disk if needed.)
If she can't, is it then possible to connect a USB hub and have two disks hooked up to the Airport Extreme?
Thanks for helping. I am constantly in awe of all the help people like you give people like me. Thanks!!!
Jakob

I've gone through the manual setup and the assisted setup and can't seem to get my MacBook to use the Time Machine. Any thoughts or help would be greatly appreciated.
Well, as the Jolly Giant points out....+this type of configuration is not supported by Apple+, so it's difficult, if not impossible, to provide a fix for something that Apple says that you cannot do. Reference these Apple Support documents regarding this topic:
http://support.apple.com/kb/HT2038
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
Your situation is not unlike other users who try this and find that one computer may backup...(usually for a limited time before corruption issues start to creep in)...but another computer cannot backup. Count me as one of those users who thought that because things seemed to work that I had somehow "beat the system".
I started getting the corruption error messages after 4-5 weeks of successful backups, so I figured that it did not make sense to continue to try to get a second computer to backup (yes, I too could not setup a second Mac to backup).
Sorry, I could not get a second machine to backup, so can't tell you how to accomplish that goal. If you want to continue to try backing up this way, you might want to also think about a second backup strategy...just in case backups become corrupted on the WD drive.
Maybe if Apple says you cannot do this, they just may be right?

I am changing to a larger hard drive on my Mac. Can I copy the Aperture library from my backup disk running Time Machine without loosing anything?

I am installing a larger harddrive on my Mac. Can I copy the Aperture library from my backup disk running Time Machine without loosing anything? I am getting help migrating everything else on to the new harddrive, but since copying the 350Gb Aperture library takes a lot of time, I am planning to do that part myself.

I found the following information on Time Machine help about restoring Aperture library from TM
Restoring Your Aperture System
If you buy a new computer or use another system at a different location and want access to the Aperture library, you can install Aperture and then transfer the library from your vault (on your backup disk) to the other computer. If you experience equipment failure or other unexpected events, such as fire or weather-related damage to your equipment, you can easily restore the entire library to your new computer from a backup disk.

Click Restore, then click Restore again.

I have backed up my disk using Time Machine. Now I want to delete the backed-up files from my hard drive. But when I do and reconnect the external hard drive, the files are also deleted on that. What do I do?

I have backed up my disk using Time Machine. I then deleted the back-up files from my MacBook hard drive.
I then reconnected my external hard drive and find the files I deleted from my hard drive are also deleted from
my external hard drive. Can someone tell my what what happened? I'm confused.

Hello,
Time Machine is not a good way to do that, when it eventually needs more room it deletes old Backups to make room.
If you really want to keep Files but remove them from the Internal Drive, then I'd get another external drive to copy or clone them to that is not used for TM.

I need to configure a new hard disk as backup disk for time machine. The set up program is running and it says it will take 9 days to backup about 56 GB. Is it normal ?

5 hours to do 6 GB of transfer is NOT normal, even for USB 2.0 so there's something wrong here. I'd say cancel it, wipe the drive and then test the integrity of the drive. Do some file transfers over to and see if it's behaving normally. It could be a bad USB cable, it could be a bad drive or bad enclosure. As it's new, I suspect you haven't really put it through its paces yet and it's important to do that first before commissioning it to serve as your "reliable backup."

How to limit the amount of disk space Time Machine will use?

On Yosemite, how do you limit the amount of disk space Time Machine will use?
I'm using a Seagate Goflex Home 2tb drive connected to my router as a Time Machine backup drive. I use this for three things 1)Time Machine 2) an occasional backup of windows document subdirectory 3) backup of music and photos for long term storage. Doing something like re-partioning the drive is not an option. I'll just go buy another drive for time machine's sole use. In addition, using software from Seagate is not an option. I don't want to use their software for different reasons (mainly the GoFlex home is really designed as a "media server" which I don't use. I, of course, use iTunes. ) On the Mac, I'm only using about 250GB total but time machine is rapidly using up space.
Apparently using a terminal command like below, used to work, but no longer works under Yosemite.
For a limit of 100gb the number below would be 100 x 1024
sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize 102400
To remove the limit, use the following command:
sudo defaults delete /Library/Preferences/com.apple.TimeMachine MaxSize
Now, I'm not too familiar with terminal and I'm not about ready to issue a command without knowing exactly what it is going to do.
Is there an easier "switch" someplace or an app that does this?
If I don't limit the size, at some point there will not be any space left for windows backups and additional photo and music files.

Hmm- added "sudo" and there was no error reported:
sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize xxxxxx
I guess we'll see.

How large should a disk for time machine be vs the hard disk

Can anyone tell me how large a disk for time machine be vs the size of the hard disk?

I usually say 2x or more but your milage may vary on that based on how much your hard drive is actually used, what sort of data (how large the files are) you typically handle and how far back you want your TM backup to go.

HT201250 Is it possible to use Dropbox or Microsoft OneDrive as the backup disk for time machine?

I have a MacBook Pro for which I have not set up Time Machine. I have a Dropbox account and a Microsoft OneDrive account, each with plenty of space to serve as backups. Is it possible to use either of these as THE backup disk for Time Machine? It doesn't appear intuitive from Time Machine on my MBP.
Thank you.

No. Time Machine does not work with "cloud" drives.

If I choose a hard drive ask my backup disk for time machine, will it clear out the data that was previously stored in my hard drive?

Hello edjhsu,
Unless the drive is in a format that isn't compatible with Time Machine, the files will not be overrwitten. However it is typically a better idea to keep your files and your backup separate, especially since files on the Time Machine drive will not be backed up by Time Machine.
