Time Machine deleted all backups

Just got a TM error message saying my 3TB drive needed 1.68TB and there was only 1.3 TB available. I thought this unlikely as my target drive should only require an incremental backup (1.68TB being a full backup). So I clicked 'back up now' (daft, I know) and Time Machine deleted everything and started a brand new backup which I immediately stopped. The TM drive still says there's only 1.3TB available which means my older backups are still in there somewhere, right?
While I don't think I've anything on the backup that I need, I'm worried how this could happen - 4 months of backups just vanished instantly.
Any ideas?
Cheers,
SNaP

Thanks for the reply, Linc,
First thing is there's no 'Starting standard backup' string, but I'm assuming the 'starting automatic backup' is our boy. I've deleted most of the texts where it says its 'deleting expired backups' (about 35 in all), and I've deleted other repetetive lines but I'm reluctant to delete more as I might be throwing out the baby with the bathwater. The string finished with my creating a new Time Machine backup on a separate drive ('Storage 3'). The original Time Machine backup was named 'Mac Companion'. The two drives being backed up were 'SSD' and '2TB HD'.

  • Exposé hot keys disabled after Time Machine "Delete all backups of file"

    I have been having the same problem that was initially mentioned in this topic:
    http://discussions.apple.com/thread.jspa?messageID=5850265#5850265
    Namely, sometimes after I restart all of my Exposé and Dashboard hot keys have been turned off (but not the Spaces hotkey, just F9-F12). My hot corners for turning off or on the screensaver work just fine, but I have to manually go in and turn back on my Exposé hot keys. Some people said it was associate with WoW, but I am not running World of Warcraft. This last time it happened (this morning), I had removed all backups of a few files in Time Machine (what's the point of having a backup of a rented movie after the 24 hour viewing period has expired?). I have been looking for a way to report this to Apple, but have been unable thus far.
    I just tested it to see if you have to restart, and you do not. About thirty minutes ago I turned all the Exposé hot keys on, and just a minute ago I deleted a backup of a file on my Desktop in Time Machine (by selecting, "Delete all backups of file ______") and the hot keys had been disabled again.
    Does anyone know if there is a way to fix this?

    Not exactly.  It did delete the existing backups, but didn't make any new ones because the file hasn't changed since then.
    The easiest way to get it to back it up is to make a minor change to it (the name or something in the contents), then change it back.  Time Machine should back it up on the next backup.
    Alternatively, you need to force a "deep scan," where Time Machine compares everything on your system to the backups.  Usually, just starting up from your Recovery HD will do that, although sometimes you have to start from it and Repair your internal HD to trigger it.

  • Time Machine: "Delete All Backups of..." does not free up drive space

    When I select "Delete All Backups of..." in the Time Machine Finder window, fiiles get deleted, but no disk space appears to be freed up.
    For example...
    Today I deleted all backups of more than 100GB of Movies and TV Recording I no longer want in the archive [the same movies have already been deleted from my Macmini].
    But Time Machine hard drive spare space has not increased at all.
    Why...

    Hi Robert J McInnes!
    Try using the following information to attempt to delete your backup filed another way:
    OS X Mountain Lion: Remove a backed-up item from your backup disk
    http://support.apple.com/kb/PH11241
    Without entering Time Machine’s starfield, you can move, copy, or delete the Backups.backupdb folder on your Time Machine backup disk as you would other folders. You can also delete folders within the Backups.backupdb folder. You can’t delete individual items inside the dated folders.
    Important: Do not use Terminal or any application other than Finder to move, copy, or remove items from the Backups.backupdb folder.

  • Undo Time Machine "Delete all backups of..."

    At some point I told Time Machine to get rid of backups of a particular file using the "Delete all backups of ..." option. Time Machine duly deleted the backups of the file and stopped making new ones.
    I've since changed my mind but I can't figure out how to get Time Machine to start backing up the file again. I know the old backups are gone, that's fine, but I want to start getting new backups.
    The file is not in the exclusions list in Time Machine preferences.
    Renaming the file isn't an option-- this file is used by a certain app that expects it to have a specific name.
    Any ideas?

  • Time Machine "Delete all Backups" doesn't recover space

    I recently deleted several iDVD and iMovie projects (>12GB) and disk images (4GB). Thinking I would recover all this HD space, I entered Time Machine, selected an old version of that file that TM had backed up, and then used the "Delete all Backups" command to get rid of them. However, instead of gaining space, I actually lost space on my TM backup drive!! It was as if TM had subtracted space instead of adding it back to my available space! Ex: Before deleting, I had 50GB available on TM backup drive. After deleting @24GB of projects, I expected to have @70-74GB available. However, I now have only 34GB!!
    I searched for these named files in TM history, and they are not there. Why didn't TM give back that space??
    Thx,
    Pengueen

    Thanks for replying. Yes, that was the first thing I checked. The files were no longer in Trash. I have since added other files to Trash, deleted them, and ran TM again. No changes. Is there any way to travel back in TM's logs to see what it did on that day? I found entries for "backupd" in the Console log, but they do not go back far enough (I need May 18, and it goes back only a couple of days).
    Thanks!

  • After reinstalling 10.6 Time Machine deleting ALL backups - Help!

    I recently reinstalled Snow Leopard. I then re-enabled Time Machine and let it run for a while. Then I discovered to my dismay that it had deleted several months of backups, and it looked like it was going to delete them all. So I turned it off.
    Does anyone know why it is doing this? I have done reinstalls before and TM has picked up seamlessly from where it left off. But not this time.
    A thought: I deleted the entire Caches folder from my Library - could that made TM think it needs to start from scratch with a brand new backup?
    Any help would be greatly appreciated.

    It may depend on exactly what you did.  If you just installed a fresh version of OSX "over" the old one, Time Machine should only back up the new version of OSX.
    If you erased the HD first, then installed OSX and used Setup Assistant to transfer everything else from your backups, it shouldn't have done a full backup.  Sometimes, however, it does anyway.
    If you erased, installed OSX, and used any other method to put your data back, yes, Time Machine will do a new, full backup.  You can't prevent it on Snow Leopard.   (There is a way on Lion).
    If you really need the old backups, your only option is to let Time Machine start fresh on a different drive.  You can always see and restore from the old one via the Browse... option, per #17 in Time Machine - Frequently Asked Questions.
    A thought: I deleted the entire Caches folder from my Library - could that made TM think it needs to start from scratch with a brand new backup?
    No.  That folder is automatically excluded from backups.

  • Time Machine Deleted All Backups After Restore

    Had a very strange thing happen...I had to do a clean reinstall of Mountain Lion and manually add back everything from various backups. After the reinstall (including a completely new computer name), I was able to access all the old Time Machine backups to restore folders from. However, once I restored one folder, TM wrote over the entire old set of backups (over 6 months worth) with a new backup of the current state, deleting everything and renaming the containing folder to the new computer name. Is there any way I can get back what it deleted? How could this have happened?
    No doubt Im done using Time Machine...no matter how anal I am about backing up, I still end up losing tons of irreplacable data (I had much of the TM backup also backed up on another external drive but, go figure that drive would fail literally simultaneously as this incident).
    Any suggestions on how to move forward, if possible at all?
    Thanks!

    Depending on how you restored your data, Time Machine may not recognize your previous backups as belonging to the same machine. It will then delete as many snapshots as necessary to make room for a full backup of all files. Once the snapshots are deleted, they can't be recovered.
    Another time, when you erase the boot volume, restore from Time Machine in Setup Assistant so that your backup history will be preserved.
    As this experience shows, you need more than one backup to be safe. I suggest you start a new backup set on another, larger, external drive.

  • HT3275 My Time Machine deletes ALL previous backups

    Every so often, Time Machine deletes ALL previous backups and starts over from scratch. It has done this several times in the last year.  I have not changed any hardware or the name of the computer. Why is this happening?  Makes me very concerned that I now have NO backups while it chugs away rebuilding a 210 GB backup. 
    Just got an error message:

  • Doesn't Time Machine delete old backups when it needs more space?

    I've had time machine running for a long time now. It worked flawlessly for quite some time.
    Today it gave me the error that there was not enough free space on the disk to complete the backup (the error message says something like there is 360 GB of data on the Time Machine drive already, 140 GB of free space and it would require more than that to complete my backup). I have a 500 GB Time Machine disk and my Mac has a 500 GB hard drive, so I should technically never run out of space.
    The Time Machine almost acts like this is the first time I've ever backed up, which is not true. Shouldn't Time Machine delete old backups to make space for the new? What's even weirder is that if I open the "Star Wars" window of Time Machine I only see one backup from March 31, 2011, but I have been running Time Machine for well over a year now. I'm totally confused as to what happened. Any advice on how to get my Time Machine back up and running (without buying a new drive) would help!

    You see only one backup in the Time Machine window because Time Machine has deleted the older backups to make space to do the current backup.
    Time machine needs some working space to do its backups, and so backing up a 500GB drive onto a 500GB time machine volume is not ideal.
    However, I do essentially the same thing, and what I do, when I have this problem, is exclude things from the backup.
    First off, figure out what you changed. If you moved things from one partition to another, then that will cause a backup of the size of the thing that was moved. This may be why you have a large backup.
    When I have this problem, I exclude large things that have changed recently from the backup. This makes the backup smaller, and means that there is less working space needed. I do this until I get a successful backup. Then I remove things, one by one, from the exclusion list, and back up after each one.
    So, for instance if you just put 4 new folders on your drive, each of which s 20GB of data and they are named A, B, C and D, add all four to the exclusion list, do a backup, then remove A from the exclusion list (leaving B, C & D on it) and do a backup, and continue like this, adding 20GB of backup data each time until none of the new data is on the exclusion list and you get a completed backup.
    Another possible issue, if you use multiple partitions, is that Time Machine may be keeping an obsolete backup of a partition that you previously reformatted. To see if this is the case, go into time machine (The universe interface) and go back to the most recent backup it shows. Click on your computer and see what partitions show up-- are any of them old ones that have been reformatted and renamed? You may be storing a duplicate backup because Time Machine does not realize that the disk that went away isn't coming back (because it has been reformatted as a different partition)
    You can right-click on these items and remove them from your backup by sleecting "Delete all backups of...." This will free up space as well.

  • Time Machine deleted "expired" backups. Why?

    I want to know why Time Machine deleted some backups although the disk has plenty of free space available.

    Backups are alright so it is not an important issue but I am wondering if something in my preferences set is wrong.

    Time Machine keeps hourly backups for one day, then daily backups for a week, etc. What you are seeing is it deleting the daily backups form more than 24 hours ago. This is what it does, nothing to worry about.

  • Time Machine : Deleting all local backups of one of several computers leaves files behind

    Hi,
    I'm in the process of transitioning my Time Machine setup. For the moment, I have a local Time Machine volume backing up three Macs to the same Backups.bakupdb folder (I had set that up two years ago before reading Pondini's Time Machine FAQ).
    Basically what I want to achieve is have a partition per computer that I'm backing up. So what I did was I partitioned a second external drive into 3 partitions, and I copied my TM partition to each of these 3 temporary partitions. I did that using Disk Utility's Restore tab. My plan was then to delete the backups of two computers off each temporary partition (per question 12 of Pondini's FAQ), to get 1 computer per partition on the temporary drive, then partition my main external drive in 3 and copy back each temporary partition to the main drive.
    (The second external drive is lent, I can't just switch to using it.)
    From what I read on question 12 of Pondini's FAQ and this reply by Pondini to a similar thread, I thought that deleting all backups of one computer via the Time Machine interface would leave me with an empty folder for that computer under Backups.backupdb, and that I could just delete this folder via the Finder. This is * not * what happened.
    After all backups for the first computer I wanted to delete off the first temporary partition are deleted, the folder for this Mac is not empty ; it still contains all the 15 dates folder of the individual backups. What's more, these date folders aren't empty either. The first 12 of them I deleted (the most recent ones) each contains a Macintosh HD folder, under which remains a System/Library/CoreServices hierarchy. The (locked) boot.efi file is alone in the CoreServices folder. The last 3 dates I deleted (the oldest backups), however, still contain an even bigger hierarchy. Applications, Library, System and Users exists in all three, with a lot of subfolders and lots of files, totalizing around 2 GB of data. Most of the files are locked, even logged into root (very diverse files : plists, dylibs, rtf files, fonts, etc) but some are not (apps, and other diverse files : colorsync profiles, dashboard widgets, bundles...). Seems like Time Machine could not delete everything. (Why ?)
    Note that I deleted the backups for one computer using that same computer, first using an Admin account for the first 3 or 4 dates and then using the root account to avoid having to always authenticate. (I didn't think it would create a problem... maybe it has?)
    When I go back into Time Machine for this computer, no backups remains. It's like if Time Machine doesn't see the data that it could't delete... This is all very strange.
    My question is : can I delete these leftover files and folders bia the Finder without fear it's going to break the backups for the other computers on the same partition ? If not, what should I do ?
    Sorry for the long post, but I hope I was clear...

    It shouldn't; when you delete a backup, the date-stamped backup folder and all it's contents should be deleted.
    Most likely, there was some sort of corruption, either on the original or the copies, that left some pieces.  On occasion, that will happen even when Time Machine is doing it's normal "thinning:" there will be a message in the log about finding a "partially-deleted" backup, and trying again.  Sometimes the second try will do it, sometimes not.  In that case, you might be able to delete it after running Repair Disk;  if not, sometimes you can delete it via the Finder.
    Under Lion only, deleting backups via the Finder is supported by Apple;  you'll get a message about how it can't be undone.  But it doesn't always work, so is recommended only as a last resort.  Holding the Option key while deleting may help with the locked files.
    If you can't get rid of the detritus, however, I'd recommend erasing the affected partition(s) and starting over.  I'd not continue backing-up to a set of suspect backups -- the way they're all linked together, there's just no telling whether you could do a full system restore successfully.
    In addition, as Linc says, even if you have some things off-site, I'd strongly recommend getting another external HD for "secondary" onsite backups.  Externals are getting much less expensive all the time, and if there's a problem with the old one (either the drive itself or the backups on it), you'll be in a large pickle.  Plus, of course, drives don't last forever.  See #27 in Time Machine - Frequently Asked Questions for some suggestions.

  • Time Machine deleted all my backups after upgrading to Yosemite!!!! Help!!!!

    Hi all! I'm in deep, deep trouble!! I was on Lion, and had all my backups on an external hard drive done by the Time Machine.
    So after I did a clean install to upgrading to Yosemite. So I was left with my Imac with nothing on it, Yosemite, and the applications that I've been installing manually.
    However, Time Machine starting backing again my Imac with Yosemite, and decided to delete ALL BACKUPS of when I was with Lion!!!
    Now I'm only have my new Backups(3 days old), and ALL MY WORK IS GONE!! (About 1TB of precised organised info!!!)
    I tried a software called Data Recovery and whilst is recovering only a 50% of all deleted data after a scanning, now its retrieving that info with new names i.e. 0001,0002,0003 and organising depending on name of extension i.e: PDF,JPEG...therefore becoming totally useless as it will take literally YEARS to put it back the way it was.
    Please HELP, I don't know what to do!!!
    My profesional life is depending on it!!
    iMac, OS X Yosemite (10.10)

    Hi there The Zach,
    I would recommend taking a look at the troubleshooting steps for Time Machine backup issues found in the article below.

  • Time machine deleted all my backups instead of the one selected

    I have a one year old Macbook Pro with 16 GB of RAM, running OSX v10.9.5 (Mavericks).  I use a LaCie 2TB external hard drive for my time machine backups, and I needed to delete some of the old TM backups to make space.
    Following the instructions at pontini.org (http://pondini.org/TM/12.html ), I opened TM, navigated to the external HD and selected the oldest folder in backups.backupdb, right clicked it and selected 'Delete all backups in [the oldest folder's name]'.  Then I went home for the weekend, and when I got in this morning, Voila!  ALL files in the backups.backupdb folder were gone!  Not only that, but there was nothing in the trash to restore!
    Has anyone else had this wonderful experience?
    Thanks,
    Casey

    Wow -- thanks for all the comments, folks, I must have struck a nerve!  I'll try to respond to all of them here, in sequence:
    John Galt: I loved your comment about "no user serviceable parts inside"!  It was echoed by etresoft, too, later in the chain; sounds like good advice if this ever happens again.  You mentioned that Yosemite incorporated a lot of changes to TM, but I'm not using Yosemite (have been avoiding this upgrade, as it sounds too buggy).  But apparently your advice holds with Mavericks, too. 
    Etresoft (3:17am): very good point -- I think that's exactly what I did.  What I'm still not clear on is: are the backup files themselves (ie the actual data being backed up, as opposed to hard links) stored in the backup folder that TM creates, or are they kept in a separate file or folder?  It sounds like it's the former, as I had originally thought.  But pondini led me to believe that, if the data WAS stored in the folder, it would not be deleted if there were any links to it in future backup folders.  From what you said, I'm thinking that's probably true IF you are dealing with a backup that's INSIDE TM, but not if its a folder OUTSIDE TM.  Is that right?  If so, this really is a pit that's ripe for idiots like me to fall into.
    Lex Schellings (3:52am): I don't think I understand your comment -- you said "All these instructions are to delete a specific file... You should never deleted a dated FOLDER".  But instruction #2 says "One or more individual backups -- it's best to use Time Machine, per the green box below" --  then, in the green box, it says " Locate the backup or item you want to delete via the Timeline or "cascade" of Finder windows".  Since I was trying to delete a "backup", what was I supposed to select, if not a folder?
    Etresoft (4:15am): that's an interesting thought, but I don't think I used the sidebar to navigate to the backup I deleted.  When I opened TM, it showed me a sequence of Finder windows with the Star Wars background, but the external hard drive in the Finder window was grayed out and inaccessible.  So I checked pondini again, and it said I could get to it by right-clicking on the TM icon in the task bar (after exiting TM), selecting 'Browse other TM Disks', and selecting the one I wanted.  After I did that, I could see the external hard drive in TM was not gray anymore, and I navigated to the first backup folder.  Apparently, that's what took me "outside" of TM, even though I thought I was inside it.  I will definitely follow up on your suggestion to go to Apple's bug report site and file a report; thanks!
    Lex Schellings (4:39am; do you guys ever sleep?): I didn't hear that pondini had died -- I hope you folks weren't close to him; sounds like he was very thorough, and trying to do the right thing.  He just didn't realize there were people like me out there.   
    I'm surprised at your comment that "the behaviour of deleting one of the TimeMachine dated folders in Finder has always been the wrong way, leading to unhappiness."  That is exactly what our tech support department (which is run by Lockheed Martin; they're supposed to know what they're doing -- at least they certainly charge JPL enough for their service) said was the approved way to delete old TM backups, and in several cases in the past, it has worked for me.  In any event, I didn't think I was deleting the TM dated folder through Finder -- I thought I was doing it through TM, as pondini recommended.  Silly me.
    Etresoft (5:24am): It's a little scary that you said "I don't know of anyone who knows Time Machine well enough to actually update it."  Were you joking?  I definitely agree with your (and John Galt's) advice that "I wouldn't recommend any kind of interference with Time Machine, especially with the Finder".  In the future, I think I will just set up a separate partition on my external drive for TM backups, and let TM figure out how to thin itself out.
    Lex Schellings (5:43am): "a magic black box" -- that's a very good take-away from this misadventure. Thanks for your advice.

  • Time Machine deleted ALL my backups prior to 4AM this morning.

    I had been using time machine and time machine editor to backup once a day at 4am. Somehow this morning instead of a normal backup it received an 'unknown instruction' and thought that there was no more room on the disk partition. Actually as of yesterday there was a huge amount of room compared with what it had been using.
    When I looked in the TM folder it showed that my backup drive and edrive had been backed up every hour since 4am, so it's no wonder that it ran out of room. I looked in the console's system log and this is what seemed Germain:

    My questions are these:
    1. What the heck was the 'unknown event' that screwed everything up and lost all my b/u's since april?
    2. How do I delete the copies of emachine and the b/u drive from TM? They take up far to much room and were never backed up before 4am today. Do I have to remove TM entirely and reinstall?
    3. Is it possible to recover the backups that were deleted?
    Is TM really this sensitive to random bits flowing around the system? And if so what good is relying on a backup system that can be wiped out by a random and unknown bit or series of them?

  • Time Machine deletes all but latest two backups

    Hello,
    Today I was backing up my macbook, with about 38 GB of space left on my harddrive, and Time Machine deletes everything but the latest two backups (from Feb 2012 to May 2012).... I had things on there from 2009. TM preferences now says I have 27 GB of free space, after the latest backup. I didn't have anything big enough on my computer to be backed up that justified deleting years of data, over 200 GB, in order to compensate for the new data that had to be backed up. Is there any way to recover the files that were erased off of my external hard-drive that were deleted during Time Machine's semi-routine back up?
    Thank you

    Is there no way to set up Time Machine such that it will ASK before destroying a (potentially valuable) "old" backup
    That's how it worked at first, on Leopard.  But many users either didn't understand it, or never got around to doing anything, so had no backups at all when disaster struck.  It was fairly common, so Apple changed it with Snow Leopard.
    Why does Apple assume that it is always the OLDEST backup (which will be hardest to retrieve) that people would be willing to loose?
    That's usually correct.  Time Machine is not a traditional archive-type app;  if you need archives, make archives.
    If you frequently need things from your backups, you may have a deeper problem.  But most likely, you just need a larger backup drive. 
    That all applies to the vast majority of users -- they have a single internal HD with less than 1 TB of data, so a 2 TB backup drive is ok, 3 TB large enough for most everybody.
    If that's not enough for your setup, you probably need a different strategy anyway.  You may have some data that changes frequently and should be backed-up hourly by Time Machine, plus something like a large media drive that's best backed-up only once a day or so by a different app, such as one of the "cloning" products. 
    there should be the option to exclude different items when backing up to different disks. Is there?
    No.  Apparently Apple wants to keep it as simple as possible, with  few options that may confuse some folks, so instead of making a decision, they do nothing  (that's not just Time Machine, either).  Remember, most of the folks using Time Machine have never used any backup app at all. 
    Apple's resisted all suggestions (and there have been many) for things like the ability to limit the size or age of backups, reduce the 10-day warning when no backup has been done, etc.  Like it or not, that's Apple's approach to pretty much everything -- streamlined, simple, easy to use.  Very successful for the majority.
    Is there any workaround other than the cumbersome procedure of turning Time Machine off, and under "options" re-select the correct set of folders to exclude every time I move from one disk to another? Not exactly what I would call a user-friendly interface...
    Best of course, is get a larger disk.  Is your data worth the price of a 2 TB disk? 
    There are some elaborate workarounds involving automatically swapping destinations and exclusions, but they're very "iffy" as they do things that TM (and OSX) don't anticipate so don't react well to.
    Effective with Lion, however, there's a new tmutil command that in theory would allow you to write an AppleScript to set a destination, add or remove exclusions and run a backup.  Many things could go wrong, of course, but I know of no way to detect which destination is available. 
    Much safer, easier, and more reliable to get a larger drive (or better strategy).
