WHat happened to my time machine backup disc?

What happened to my time machine backup disc? It is no longer visible from finder or the time machine utility.

It doesn't show up in Disk Utility, and it is not discoverable from the Time Machine setup.
I've restarted, shut off and on, etc. It was displaying in the Time Machine list of discs but erroring out on actually doing a backup. I removed it to see if I could reconnect, but now I can't even find it.
All cables are plugged in securely.
My guess is this is the is related to the 10.9.2 update.
Any other ideas?

  • What happens if you Time-Machine backup an encrypted file-vault HD?

    This is related to my previous post - but deserves special mention for those people who are using time-vault AND Time-Machine.
    My question is this: If the backup of my Hard-drive is encrypted, and I then reinstall from backup, what will this situation likely produce?
    This is what I have done. I also Archived and installed my Mac prior to installing from my Time-Machine backup.
    I now have an error message that displays the following message at the login screen:
    "Unable to log into the file-vault account "......." at this time. An error has occurred."
    My password IS CORRECT. I have not changed it, and the log in window does accept my password, but it doesn't progress any further than the error message I gave above.
    I'm wondering if the encryption process of file-vault is linked directly with the original installation I had of Mac OS-X before I Archived and installed.
    Any thoughts/knowledge/Insight?? I want my old Mac back! (I don't recommend using file-vault). Any body else had this problem or can see what is happening to me here?
    Thank you

    I just did a backup, moved a folder with 600mb of images into a different folder, and did another backup. The free space on the backup drive dropped by the size of the folder's contents. The backup copied the files as I watched in System Preferences, and it looked like it was really copying the files to the external drive again. It looks like Time Machine isn't as smart as I hoped in this regard.
    Still - I'd think the wasted space is only in the every-hour-for-the-last-24-hours bucket of Time Machine. I'm guessing the every hour backups are like a sliding window, where a backup that's 24 hours old drops out every hour rather than all the hourly backups getting wiped at midnight and starting over.
    Regardless, only one version of the moved folder will eventually be stored as the daily backup for that day. I don't have proof, but that's what I think.
    So, if you've moved a bunch of folders around or renamed them, the extra copies of the same exact files should drop off within 24 hours.
    That's my interpretation, but I'm in no way positive!! The lengthy Ars review didn't offer an answer to this question.

  • What happens to my Time Machine backups if I upgrade to Mt.Lion?

    I have Snow Leopard and have been backing up using Time Machine. If I upgrade to Mt. Lion what do I do about my Time Machine backups? Do I just keep backing up from where I left off, or do I have to somehow start over?

    You should be able to continue from there.  Note though some applications that are Snow Leopard compatible are not Mountain Lion.  Keep at least two backups just in case, and have your 10.6 installer disc ready if you find a necessary application or driver is not compatible.

  • What happens when the Time Machine drive is full?

    I'm on my second iMac. My first one (G5, 1984) died, and I replaced it early 2010 with an Intel mac. The transition when exceedingly well largely due to Time Machine. I just hooked the Time Machine drive to the new system, and I was soon back up running!
    My home folder has 70GB of data. The Macintosh drive has 105GB of data and 395GB free. The Time Machine drive has 220GB used and 30GB free.
    1. What happens when the Time Machine drive is full?
    2. Do I have control over what backups get deleted?
    3. If lightning strikes twice, will I still be able to restore my Intel mac like my G5 mac, even if backups get deleted?
    4. Is there anyway to control what backups/backup files get deleted?
    5. Any other thoughts?
    Thanks.

    Do you mean all of them? The entire Backups.backupdb folder?
    That's a large mess. First, even a normal delete will take a very long time, as there are probably hundreds of thousands, or even millions, of files. Your best bet by far is to simply erase them with Disk Utility -- that will only take a few moments. If your TM drive has a single partition, see #1 in [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html]. If there are other partition(s) on the drive, see #2 there.
    If not, and you only deleted some of the folders, you have a different, worse problem. Unfortunately, Apple doesn't do a very good job of warning folks: +*Never move, change, or delete anything in your backups via the Finder or Terminal.+*
    You shouldn't have to delete backups at all, since Time Machine will do that automatically when the disk/partition gets full. But you can do it without harm via Time Machine. See #12 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
    A normal delete will take a very long time, as there are probably tens or hundreds of thousands of items, each of which must be individually deleted. A secure delete will take much, much longer, as each deleted file must be overwritten with zeros.

  • HT1338 Error preparing Time Machine backup disc- size error usually not being multiples of 512, encryption

    Trying to encrypt Time Machine backup disc getting message  - Error preparing Time Machine backup disc- size error usually not being multiples of 512, encryption.

    I got the same problem.
    But I think it cannot be related to not being a multiple of 512.
    As when I devide the number of bytes 3.000.592.982.016 by 512 is equals 5860533168.
    3.000.592.982.016 / 512 = 5860533168.
    So what could be the real problem?
    With kind Regards

    My time machine backup disc has apps from Mountain Lion that won't open now that I have Yosemite.  They all say need to be upgraded to Yosemite. Go to app store. But app store sees that I have yosemite so doesn't even show me an udate option. How can Update these files??

    How do you know they won't run in Yosemite? You're not trying to fiddle with stuff in your backup from the Finder, are you? If so you are likely to render that backup unusable.
    WHen when you restore them from your backup, they should be updateable.

  • How do I reformat my time machine backup disc

    My time machine backup disc comes up with error:
    Files can’t be copied onto the backup disk because it appears to be read-only.
    Disc utility can't fix it and gives me the following message:
    Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
    How do I reformat that drive?

    Re: How do I reformat my time machine backup disc Oct 13, 2012 5:32 PM (in response to Jim Tee)
    Hi again Niel:
    Regarding "use the Erase option in disc utility to reformat my backup disc:
    I tried the erase again and came up with the following fault messages.
    "Mac OS X can’t repair the disk “Time Machine.
    You can still open or copy files on the disk, but you can’t save changes to files on the disk. Back up the disk and reformat it as soon as you can."
    Also
    "Disc erase failed
    Disk Erase failed with the error:
    Couldn’t unmount disk."

  • What happened to the Time Machine scheduler?

    I upgraded to Lion and now I can't seem to find it anywhere in system preferences.

    I would like to be able to schedule my time machine backups too. Every hour seems excessive for a lot of people. It seems like my computer at work is constantly backing up. I feel like it is slowing my work down. Even if it is just setting the backup to every 2 hours or every three hours. I don't need to pick a time, just have it happen less if I desire.

  • What has renamed my Time Machine backup partition?

    I have no idea what has happened here, but between my last TM backup (which was Friday, June 29th) and today (July 2nd), my backup partition has been renamed from `Name` to `Name_1`. Log files do not show any system process that occured, and the drive sat idly in my desk over this time period. There is so much odd going on here:
    1. Backups appear to be progressing as usual
    2. `Name` is now a partition under /Volumes/ that is owned by root; I have full permissions to `Name_1`.
    3. `Name` contains .Spotlight-V100 and nothing else.
    4. Depending on whether I am using Cmd-I or Bash, I get different info as far as when each of these were created, modified, etc.
    Plus a couple of other odd bits.
    Anyone ever run into this? I have had multiple problems over the past couple of months since installing a new HDD (posted a question or two on this forum, did not get any responses). These problems seemed to largely resolve through a few means, and backups have been going relatively smoothly since. I am and have been using a WD My Passport Elite 500 GB to back up a late 2008 MBP running 10.6.8. Like I said, before getting the new HDD mid-May, I never had a problem. This is the oddest of them all for sure. Any help or insight would be appreciated (do I even need to worry?).
    Screen shots below illustrate attempting to cd to the directory (using bash alias tmj "time machine jump" which should've taken me to the directory right above the incrementals) and finding it wasn't there, then being denied access through manual cd.
    Finder windows show the discrepancy between a "normal" window (bottom finder) and one I opened after cd'ing to 'Cortical' (`Name`) using `open .` from the command line.

    It doesn't show up in Disk Utility, and it is not discoverable from the Time Machine setup.
    I've restarted, shut off and on, etc. It was displaying in the Time Machine list of discs but erroring out on actually doing a backup. I removed it to see if I could reconnect, but now I can't even find it.
    All cables are plugged in securely.

  • Getting Photos from Time Machine Backup disc to new mac

    Hi! I have everything saved from my macbook on an external hard drive via time machine. When I go into time machine and the back up from my mac book, I click on users and then photos and then iphoto library and have no problem seeing my library...
    BUT
    Now I am trying to download all of the photos from the backup onto my husband's macbook. When I go to import on iphoto and then go to the backup disc... I cannot select iphoto library. It is a faded color and won't let me select it. It makes me worried that I can not access my pictures from another computer and cannot download them onto my husband's computer.
    What is the problem and how do I resolve this?
    Thanks!

    I think it's because you're trying to restore to a computer with a different Owner. I would post that on the Time Machine forum.
    Regards

  • Two hard drives connected to Airport Extreme. How to include one of them in TimeMachine Backup and use other disc as Time Machine backup disc?

    Hi,
    the title says it all. I've got an airport extreme and two hard drives connected to it. My idea was to use one as my additional storage (say DISC STORAGE) and the other one as my backup drive (say DISC BACKUP). I would like to backup my mac AND DISC STORAGE together to DISC BACKUP using time machine. My mac has 256 GB HDD, DISC STORAGE is 1 TB big, DISC BACKUP 2 TB. So there are no space issues.
    Problem: DISC STORAGE is not included in Time Machine's backup to DISC BACKUP. At the moment, only the mac is backed up to DISC BACKUP.
    Does anybody know if and how I can include DISC STORAGE in the backup process?
    By the way, DISC STORAGE is not listed in the "exclude from backup" list in Time Machine.
    Thanks!
    Arne

    Unforrtunately, Time Machine cannot backup from a network drive to another drive. Time Machine will only backup a Mac and a drive that is directly attached to the Mac, via USB or FireWire.
    You will need to use an application like Carbon Copy Cloner or SupoerDuper to be able to backup from DISC BACKUP to DISC STORAGE.

  • What is password for time machine backup

    I have bought a mountain lion compatible wd ny book live 1 tb external hard disk. While connecting through wifi, it is asking for password of system administrator. It is not taking either apple I'd or other download, application install passwords. What do I do ?

    You almost certainly do not have a Time Capsule, however to look it up go to Apple's online store and search for it. Bottom line if you want TM to work properly and reliably please follow the directions of connecting the EHD directly to your computer or purchase a Time Capsule and connect using the enclosed instructions.

  • I am using an external drive for a time machine backup. It has disappeared from the desktop. How do I get it back again?

    My time machine backup disc, which has been working ok for a couple of years has suddenly disappeared from the desktop. The time machine program tels me it is unavailable. I have checked that the drive is working by booting up in Windows. and Windows can see it  and read it ok. What has gone wrong, and how can I fix it?
    I have tried unplugging it and reconnecting, but it is still apparently not seen by the system.
    I could use Windows to reformat it, and start again, but this would loose all my previous backups, and I've no guarantee that the system would notice it even then.
    Has anyone any ideas?

    I think it's formatted on FAT 32 system, but I'm not sure. It's been working for a couple of years so far without any problems, so I think it must be compatible with Mac. The problem is that all of a sudden, the Mac doesn't acknowledge that it is present.

  • Time Machine: backups lost

    What has happened to my time machine backups?
    I was backing up to an external drive. TM has always worked perfectly. Just a day or two ago I noticed Time Machine was not completing backups.
    I think it may be because my external drive does not have enough room on it now.
    But I thought TM was supposed to delete older backups if this happened.
    I cannot find any trace of any backups on the external drive.
    I cannot enter into Time Machine, there does not appear to be anything there.
    I think the above window indicating that there is not enough room is because something has happened to my backups and it is now attempting to start a new one all over, this happened after I started getting the failed to backup options and I went into Time Machine and attempted to delete some backups but did not.
    Anyway, before this happened I should have only been putting very little files in the backup, I should not have to make such a large backup now. I thought this was all done incrememtally and I thought that Time Machine was supposed to delete older files if space starts being a problem.

  • Looking to format and start fresh....time machine backups

    I have a 13" MBP purchased with Snow Leopard, currently running Lion.  I am looking to start from scratch - just because I have a ton of stuff on here that I don't need, a bunch of junk.  I just feel like it is time to start over. 
    That being said, I have my re-install disk that came with the laptop.  I also have time machine backups from earlier today.
    My questions are - if I go through with this and re install fresh-
    1.  How do I get back to Lion (I ultimately want to get to mountain lion)
    2.  What will happen with my time machine backup from my laptop now (pre-format) once I start running time machine on my laptop post-format?  Will it over write?  Will I still be able to access the archived data?
    Thanks

    You don't use the 10.6 disk or the TM drive.
    You need to copy your Users folders to a regular external storage drive, not just TimeMachine as it will restore stuff you don't want.
    10.7 has a Recovery HD partition on the drive which you hold command r boot into to erase and install OS X Lion onto the Macintosh HD partition. Provided you have your AppleID and password, fast, good Internet connection.
    Create the same named user on the machine as before.
    You then hit AppStore and update to 10.8 if your machine qualifies for it.
    You then hold option key and click on Purchases to redownload any software you installed from there.
    You if 10.8, then need to turn Gatekeeper in System Preferences to "Install from Anywhere"
    You then install 10.8 compatible software from outside sources.
    http://roaringapps.com/apps:table
    Last you connect the external storage drive and go through your folders and cherry pick what you want and don't want on the new setup. Nothing from the User/Library folder.
    Then once that's complete, you create a couple of bootable clones, each on their own external drive using Carbon Copy Cloner, these are hold option key bootable drives for restoring or use when the hard drive dies or becomes corrupted.
    You then hook up TimeMachine, it will update to 10.8 and your new configuration wiping all the old stuff pretty much away due ot the large change, or else you can keep it disconnected to restore back to 10.7.5 with, but you need to erase the drive c booted from the 10.6 disk first as you can't go backwards with TM, only on a wiped drive.
