Does defragmenting the start up drive have implications for Time Machine?

Will Time Machine have to create a totally new backup if I defrag the startup drive?

Depends how you do it. If you erase and restore, yes: http://support.apple.com/kb/TS1338
If you're using a 3rd-party utility that just moves things around, probably not (but I can't swear to it).

  • HT3275 How do you Format the external hard drive been used for time machine?

    Error reads "Not enough space on the external hard drive" How do i format the memory and start again?
    Thanks Geremy

    ON an external hard drive.. that is easy.. just open disk utility and reformat it. Make sure you use Mac Extended Journeled. (HFS+)

  • HT3275 Verbatim drive I use for Time Machine backups got messed-up. I erased it.  It does now perform its regular back-ups.  HOWEVER, I can't "Enter TM."

    I am running OS 10.6.8.  The external Verbatim drive I use for Time Machine backups got messed-up, so I erased it & chose it as my back-up disc for TM.  It does perform its regular back-ups.  HOWEVER, when I try to "Enter TM" nothing happens?

    I read some hints about this issue from similar queries, including "Restart your computer".  That did the trick!

  • "No configured AirPort base stations have been found."  I can see the content of the TimeCapsule's drive in finder and Time Machine but it no longer is making backups. Ideas?

    Bought new TimeCapsule March 2013. Worked fine. Now get "No configured AirPort base stations have been found."  I can see the content of the TimeCapsule's drive in finder and Time Machine but it no longer is making backups. Ideas?

    Make sure that you have AirPort Utility 6.3.1 installed on your Mac.
    AirPort Utility 6.3.1 for Mac - Support - Apple
    Then, power off the entire network...all devices...in any order that you want
    Wait a minute, then start the modem first and let it run a full minute
    Start the next device connected to the modem, which may be your Time Capsule and let it run a minute
    Keep starting devices one at a time the same way until the entire network is back up
    See if AirPort Utility can "see" the Time Capsule now.
    If yes, try another backup. If you encounter an error message, post back with the exact message.

    Those look alot like file names and not infection names. I don't find any reference to anything like that on Norton or VirusTotal. Since you said these were Trojans, I would expect to see "Trojan" as part of the infection name.
    ".jar" files are executable Java applets. The random alpha-numerics would seem to indicate a cache file, likely from a browser with Java enabled. And we all know what ".zip" means.
    Worst case is that you had Java enabled in a browser and were infected by one of the late variants of the Flashback Trojan over a year ago or one of a couple of other attacks using the same vulnerability but targetted against a small number of political sympathizers. Much more probable is that thes were Windows only Trojans. Hopefully you have a fully up-to-date OS X, including Java, and have disabled Java in all your browsers by now.

  • When attempting to upgrade my iMac from Snow Leopard to Mavericks, I receive the message "This disk is used for Time Machine Backups" when I try to select the lone available hard drive.

    When attempting to upgrade my iMac from Snow Leopard to Mavericks, I receive the message "This disk is used for Time Machine Backups" when I try to select the lone available hard drive.  I have ensured that Time Machine is turned off.  Upon some Google research, some who reported this problem were told to delete the folder backup.backupdb, but I do not have this folder on my Mac.  Any suggestions?

    The folder would be at the root of your hard drive. Double-click Macintosh HD and look there.
    If it isn’t there, I’m not sure what it is seeing.

  • Down loaded Mavericks, will not install on my computer because it says "this hard drive is used for time machine back up".

    Down loaded mavericks, it will not install on my computer because it says" this hard drive is used for time machine back up". So I used my old computer  hard drive for back up and reloaded the program but it still says the first hard drive is being used.

    Welcome to Apple Support Communities
    Make sure you have selected your MacBook Pro's hard drive as the destination to install Mavericks. If so, you have the "Backups.backupdb" folder in the root level of your hard drive.
    That's the folder used by Time Machine to store backups of your files, and the Mavericks installer understands that your internal hard disk is the Time Machine drive.
    To fix this, open a Finder window, select the Go menu (on the menu bar) > Go to Folder, and type:
    Then, delete "Backups.backupdb", empty the Trash and run the Mavericks installer. Finally, install OS X Mavericks

  • Cannot install Yosemite as hard drive is used for Time Machine Backup, How Do I Change This?

    I have a 2010 MacBook Pro and when I attempted to install Yosemite the MacBook Pro Drive is greyed out and a message appears that read,"drive is used for Time Machine Backup." How do I change this to install Yosemite?
    Thanks,
    Scott

    Well, if you don't want to use that drive for Time Machine anymore, then you should format it using Disk Utility. Then you can install Yosemite on it.
    You should, of course, have another full backup somewhere. I really can't state this strongly enough: You should have a full and complete and up to date backup of all your data before you upgrade to OS X Yosemite.

    Cannot install Mountain Lion on my hard disc, as I keep getting the message" 'This disk is used for Time Machine backups'. Which it isn't - I don't use Time Machine

    Check to see if you have a folder named "Backups.backupdb" at the root level of your hard disk. That can cause this error message.

  • Cannot install Mavks. Get the message that HD is used for Time Machine B/U. Not true. Also Time Machine is turned off.

    Cannot install Mavks. Get the message that HD is used for Time Machine B/U. Not true. Also Time Machine is turned off. Running OS 10.8.5.

    That message appears when there's a "Backups.backupdb" folder in the root level of the OS X volume. This folder is used by Time Machine to store backups, being this the reason why the OS X Mavericks installer detects the OS X partition as used by Time Machine.
    To delete it, open a Finder window, select the Go menu (on the menu bar) > Go to Folder, and type:
    Then, delete "Backups.backupdb" and empty the Trash. Finally, open the OS X Mavericks installer in /Applications and follow the steps. Make sure you have got a backup of your files before upgrading and check that your apps are compatible > http://www.roaringapps.com

  • Two 2TB internal drives in tandem for Time Machine; only one backup deletes.

    I'm using two 2TB internal drives in tandem for Time Machine and deleted some backups while in Time Machine. They deleted from drive A, but drive B still has the files. Is there a way to delete these? I tried unmounting drive A in Disk Utility but then I can't enter Time Machine.
    I love the dual backups, but should I be able to do dual deletes of all backups? I don't see a way to accomplishg this except to force Time Machine to do a backup, then do that again so it switches drives, but that seems a bit convoluted.
    If one of you guru types has an answer I'd be most interested.
    Thanks.

    You can manually deal with this by using the "Browse Other Backup Disks" function which is accessed via holding the opt/alt key and while selecting the TM icon in the menu bar.
    You can then delete the instances of the desired files in each backup set.
    Not elegant, but I wouldn't expect that this will be done automatically, as there are a lot of permutations of how you use multiple backup sets.

  • Can i use time capsule for external h drive and also for time machine?

    Can i use time capsule for external h drive and also for time machine?

    Hello, vascocaco.
    If I understand correctly, you're wondering if you can use your Time Capsule's internal hard disk both for Time Machine backups and as an ordinary drive. Is this your question?
    You can, but Time Machine backups may take longer.
    To do it, you should partition your Time Capsule's hard disk to create one volume for the backups and one for other files.

    From the Finder's Go menu, choose Computer:
    Double-click your hard disk icon. It is usually named "Macintosh HD":
    Look for this folder:
    Drag it to the Trash.
