Warning: SERIOUS Data Loss Bug in 10.5.2 Time Machine

I've been backing up an aluminum 10.5.1 iMac and two other computers to a network drive on a 10.5.1 MDD G4 for several months. After updating both machines to 10.5.2 this morning, Time Machine deleted ALL of my backups for the iMac. system.log tells the sad story:

The sparsebundle was over 100GB, even after Time Machine erased everything. My best guess is that Time Machine isn't compacting the sparsebundle after it deletes, and is checking the network drive's free space rather than the sparsebundle's free space, leading TM to delete everything in the bundle in an attempt to free more space.

FileVault isn't involved here. Time Machine uses sparsebundles when backing up to a network share on another Mac.
In regards to the UUID: I didn't do anything that should cause this to change. Looking over system.log some more, this message didn't appear until after I installed 10.5.2. Time Machine was working properly just minutes before doing the update.

Data Loss -- maverick kills mbp17 and related time machine backup

We started several days ago to install Maverick on our MBP17 / 8GB. The installation runs fine and we are excited to use the new maverick OS.
B U T
After reboot the system becomes unusable because all available memory was eaten up by kernel_Task and mds_Stores immidiately.
We contact apple support and the answer was incredible: "You should not use Maverick because it is new and the first version"
End of support. Ticket is still open and no answer is arriving to us.
Unfortnately we need our system for real work and we lost already some days !!!!. So we started a reovery process by our own knowledge.
Now we started to recover our system from Time Machine backup at our OS X Server ML. Things are becoming worse !!!!
First time recovery runs fine ( despite the duration of more than 8 hours ) but system doesn't boot. OOhps !
Second Timme recovery was done using Ethernet and gives us a booting system with Mountain Lion after 7 hour.
But the Time Machine Backups for this MBP17 at our server are no longer Available. Back volume missing, in use or whatever as error message is known to Time Machine.
Two Years of data are gone
Thank you Apple it's worse than your card application and even more worse than windows 8 upgrade process

Serious data loss bug remains!!

I had filed a bug report on this for v1, but there appears to be no change in Pages version 2.
Pages has no problem allowing multiple people to open a file on a server at the same time. Each time any person hits save, their version of the document replaces the current version (which may contain changes made by others who have the document open). No warning is given to any party.
This makes it very hard for multiple people to collaborate on a set of shared documents, as they won't know who might already be editing the document.
This seems glaring and dangerous behavior.
Does anyone know a good LIGHTWEIGHT check in, check out system that can be used to work around this?
-Preston

As I recall, no where in the Pages documentation or on the website does it indicate that there is a collaboration system in place to allow what you are doing.
Pages let's one person work on a document at any one time One person opens, and one person can save. If you have opened it you can save it. If someone else has opened it in the meantime, they can save it too. If one overwrites the work of another, that is indemic to a single-user-oriented document and program.
What you are doing is like five people trying to steer a vespa, and yet only one person can actually sit on the bike.
It's not a bug, but by all means do send feedback to request a collaboration feature or proper versioning system for netowrk saving be implemented in the future.

Massive data loss bug

Leopard's Finder has a glaring bug in its directory-moving code, leading to horrendous data loss if a destination volume disappears while a move operation is in progress. This author first came across it when Samba crashed while he was moving a directory from his desktop over to a Samba mount on his FreeBSD server. Here's the link - http://tomkarpik.com/articles/massive-data-loss-bug-in-leopard/ I hope Apple would get this fixed soon.

That is actually the safest and easiest option.
Seems easier to command-click drag and drop to me. Losing data is not acceptable under any circumstance.
Everything has been precisely calculated
I don't think that data loss is something that was purposefully precisely calculated.
A short term fix would be for Apple to disable the command-drag n' drop altogether, long term would be to fix the root issue in the first place.
Am shocked to hear that this data loss bug has been known about since 10.3.

"backup is too large" warning, yet I can't see old backups in time machine.

I plugged my Firelite drive into my Macbook Pro and was warned that I haven't backed up in 50 days (not so). When I try to back up I get a warning that there's not enough space on the external disk. When I enter time machine there are NO previous restore points visible, yet they are there when I open the backup disk in the finder. It seems it's trying to back up my entire system into the remaining free disk space instead of running the incremental backup it's supposed to be doing.
Is there any way to fix this? I know the simple answer is to buy a bigger backup volume but I don't see why I need to, since I didn't really change much between this and the most recent backup. Restart changes nothing.

Thanks James, great info.
When I hold down the option key I find that there are 2 drives listed. One is the backup with my computer's name "trilobite" and the other is called "trilobite 2". Choosing the proper drive reveals all my previous backups. The finder also shows the a folder on the disk called "trilobite 2" but when I delete it, TM just creates another.
Working through your suggestions, I just realized that the videocard/logic board replacement I had on Jan.12 may certainly have been a factor. I had a lot of video issues on Jan.2 and was restarting and zapping the PRAM etc. over and over (successful backups stopped on that day). Funny, TM never complained of any difficulties.
Since I don't have any recent backups anyway, I guess I'll just try erasing the whole backup disk and reset TM.
Here is the TM widget log:

How can I migrate data from old macs second harddrive in time machine backup to my new mac?

Hi,
I have a little problem migrating all my data from my old Macbook to my new Macbook. I had two harddisk installed in my Macbook and did make a backup to a USB Disk. It seems that both harddisk are included in the backup. I can see them in Time Machine.
Now I want to restore my data to the new Macbook Retina. Unfortunately the Migration Assistant only shows the system disk, but not the data disk.
How can I access the data disk in the backup to restore the data to some directory on the new Macbook? The data is mostly the iTunes Library of my old Macbook.
Regards

If the migration assistant doesn't work and you have no backup then you will have to take another path that involves a little more manual work. Anyway in your situation a fresh start seems like a good idea. So set up your new Mac with the same username and afterwards copy your user folder from the old to the new either using your ethernet connection or an external USB drive. This will also bring your user's Library folder along and retain most of your settings at least as far as they are applicable in Mavericks.

Transferring data to new (replacement) hard drive using time machine

My MacPro has crashed and after replacing the motherboard with no improvement, Apple thinks I will likely need a new hard drive. The cost of new drive and labor to install it is covered by Apple Care, but not for the technician to transfer to the new hard drive all the software data installed subsequent to purchase.
I have Time Machine on a second hard drive. Assuming that this drive is OK, can I transfer the data myself from Time Machine opened at a point before computer crashed?

Hi V.K., was just reading your instructions for jumper25 about transferring all info to a new HD and had a question. I am in the same situation where i have bought a new 320Gb to replace the OEM 120Gb in my MBP. Everything is very straight forward from what you have posted but i only have the original Tiger 10.4.9 install DVD and I am running Leopard 10.5.5. Will I be able to use my Tiger install disk and then use my TM back up even though it Leopard? Or will I need a Leopard install disk to complete? Also is there another way around this problem if i can not use the Tiger disk such as mirroring the 120Gb disk on to my 320Gb?
Thanks in advance for your time and expertise.

"Latest Backup" time/date is incorrect for OS X Server Time Machine backups

I administer a OS X Server that provides Time Machine backups for clients across our small business network. I'm running Server on a Mac Mini (2.3 GHz i7 with 8GB RAM), and after going from Mavericks to Yosemite (and from Server 3 to Server 4) the other day, the TM backups are still running hourly, but the "Latest Backup" times are incorrect. Has anyone noticed this behavior? In case it matters, none of the clients currently being backed up are Yosemite clients. I mentioned this because for our older clients (10.6), the "Latest Backup" times/dates were always listed as "Unknown" in Server 3, and continue to be in Server 4. Thanks!

I also had to restart the server and client after applying the "fix" I described above. Basically, no user should have multiple, simultaneous file sharing sessions on the server. But even clearing the user sessions does not resolve the problem beyond the next Time Machine backup, so I also tried disabling and enabling file sharing, but the problem also returns after doing this. Only restarting both the client and server after clearing the sessions has worked for me when I have this problem. The problem may return much later, but this work aroudn definitely works as a temporary solution.
Next time I encounter this problem I will try restarting just the server or just the client, because it is unlikely that the problem exists due to something on both systems. Server 3.x is definitely not as stable as it should be, but for my use, it is getting the job done.

Data are back-upped correctly, but in Time Machine mode the stacked panes are all black

I can access the files on the Time Capsule disk manually. After entering Time Machine mode the back-up dates and times are displayed correctly on the right side of the screen. But all panels are black, except the top one. (On all my computers.) Is this a known problem? Erasing the disk and starting over didn't help.

Wow. I spent all day researching and even spoke to Apple and didn't find that anywhere! Where did you come up with it? Yes it works, but I do have to mount the disk image, and then Time Machine sees all of my backups including the most recent. So there should be a way to make it see this as the regular time machine disk and save the extra steps, no?
Probably not.
Have you had any of the following lately: hardware repairs to your Mac (if so, what); done a full restore; gone several days without a successful backup; changed your System Name (via System Preferences > Sharing)?
Do you have a Time Capsule, or a USB drive attached to an Airport Extreme?
There's another thing you need to watch for. TM may not delete ("thin") the backups in the old set of backups, which means when it runs out of room, it may delete newer ones instead.
If none of your backups appear via +Enter Time Machine,+ you're probably ok. But if recent ones do, and older ones don't, you may not be.
To monitor this, Download the +Time Machine Buddy+ widget from: http://www.apple.com/downloads/dashboard/status/timemachinebuddy.html. It shows the messages from your logs for one TM backup run at a time, in a small window.
Among other things, each deleted backup will be documented here. If the proper ones are being deleted, you're not going to have a problem. Note that many recent backups ("daily" backups) should be deleted after 24 hours, in accord with the schedule on the TM Preference panel.
More info on some of the common messages are in item 7 of the +Frequently Asked Questions+ post at the top of this forum.

Moving backup data from one disk to another in TIME MACHINE...

Happy Holidays to all...
Just bought a TC and love it; my main mac took about 48 hours to back up, but now is on line with it; I have a macbook I have been backing up to an external HD for a while now and wonder how I can move the backup file from this HD to the TC. Is is possible? If I simply respecify the TC to be the TM disk, what happens to the current HD? Don't want to make a move until I know the consequences...
Thanks.
Ger

Thank you so much; bummer though; I have about a years worth of TM on my attached drive.
Yes, I did it wirelessly; I thought that was the point of TIME CAPSULE. It has been a pain updating every hour though; it takes a bit of time each time; I found a great utility, though, that allows you to set the backup frequency for as long as every 12 hours; This makes it more practical to have the wireless backup. very cool:

Beware of iTunes' Reorganize Library feature - DATA LOSS!

Once again I had to report an INFURIATING DATA LOSS BUG in iTunes to Apple.
I have a large library of music, movies and TV shows-- all painstakingly purchased, ripped and imported onto a 2 TB external Lacie NAS. Everything works fine-- UNTIL I dare to use iTunes' Library -> Reorganize Files feature in an attempt to clean up iTune's inability to keep an external drive properly organized as media is added.
This time, iTunes saw fit to DELETE all of the .m4v files from THREE ENTIRE TV SERIES. With NO WARNING OR ERROR. The files are simply gone off my NAS. These will take weeks to replace!
I reported this bug back in iTunes 10.4 and it STILL EXISTS in iTunes 10.5b48. So beware of using this feature, even in the upcoming version of iTunes.
iTunes should NEVER delete your files without warning no matter what! Not under ANY circumstances!

Since this is an iTunes question, it might be better to post in the iTunes for Windows forum.

[DATA LOSS] I closed the Tab Groups and all my tabs dissapeared. How can I recover the tabs in Firefox 26? Would you please just delete this feature?

Thank-you in advance for reading all of this.
A slip of the mouse in trying to return to the left-most tab caused the tab groups feature to take over the window. I completely failed to comprehend what I was looking at and closed the thing by clicking the x because I damn sure didn't want what I was looking at. Undo close group? Of course not, I didn't want a group in the first place. Hey! My tabs are completely gone now! So in just a few steps all of which seemed innocent, I have lost all but ten of the tabs that were open, and those were only the most recent ten (and actually older tabs would have been more valueable than newer so insult on top of injury).
I don't think increasing the number of undoable tab closures is the answer. I think getting rid of the tab groups feature all together is the best way to go. I seem to have lost all the tabs I had open, irretrievably, and some of them had been open for WEEKS so they can't be reopened from history.
The tab groups feature is a data loss bug. Please remove it from the UX completely. If you have to figure out a way to grandfather people who actually have a tab group, fine but don't further vex me with it, please.
The reason this catastrophe has occurred is that your feature, was so discoverable that I activated it by mistake, and the UI after that had to be learned on the spot, yet was too complicated to learn. You really should withdraw it until you can figure out how to keep the UI for it from causing data loss such as I have experienced this morning.
Also, there may be other questions on this feature which are from a certain point of view the same as this one. It's hard for me to tell for sure. None of them had a true resolution so that's why I posted this one, also I'm seeking a specific fix, removal of the offending feature.
Why remove the feature? Because if I allow in my discussion the possibility of retaining it, it will stick around in its present and dangerous form until your team is done bikeshedding the new form it should take. Instead I want you to delete the feature and then require its champion to convince you that a new incarnation won't cause data loss before you allow it back in.
Fellow users, if you know of a way to recover all 50 lost tabs from an "undo close tab group incident", I would be grateful for that advice, but I would still believe the feature should be deleted. Some of the tabs have been retained for months so digging them out of the history is not practical.

I am not 100% certain but I am fairly sure development of this tab feature has ceased and it is likely to be deprecated. I am even less sure what the replacement will be.
Thus forum is not the place for discussing development issues or feature requests. (Developers do not use this site)
*You could comment using feedback <br /> https://input.mozilla.org/en-US/feedback
*Or try to find a developers forum or mailing list <br /> http://www.mozilla.org/about/forums/#general-development
I have not tried this and am not even using Windows at present but the tabs groups are stored as entries in the sessionstore.js files. Firefox has such a file plus sometimes numbered copies and a backup copy. Firefox will have re-writen these files but I suppose there is a posibility the Windows OS may have kept copies.
* see http://windows.microsoft.com/en-US/windows7/Previous-versions-of-files-frequently-asked-questions
* http://kb.mozillazine.org/Sessionstore.js Note the files are kept within the Firefox Profile
** Firefox Button -> Help -> Troubleshooting [open profile] (or some thing similar) is one method of locating the profile.
Find and backup any current sessionstore.js file. Consider also bookmark or otherwise recording anything you have open. Now find any previous versions and try putting them in Firefox's profile before restarting it.

Data loss after routine synch with m515

I just did a hot synch and discovered that almost all of my datebook info has been wiped out from both my handheld & the desktop!! the synch log contains the following message: "-- Date Book
   - Some handheld records were not copied to your PC. Your computer may be full or you may have reached the maximum allowed records on the desktop."
Only about 5% of past calendar entries are still there, and about 10% of current/future entries.
I went to the datebook.bak file but it is the same as the data file inspite of the fact I only synched the one time.
Can someone please tell me there is hope for retrieving my data? Should I just throw the Palm pilot out the window and go back to good old fashioned pen & paper? This is not the first time I have suffered a complete data loss with these things - the last time was when I upgraded to a new palm & in spite of following the directions exactly, everything was lost.
Thanks much, Janette
Post relates to: Palm m515

Thanks a lot for responding, Aeisha. I did the search & found the largest datebook.bak file.   I opened the palm desktop & used the import option. I selected the exact location specified by the search results but the files don't match! For example, the file found by searching is a bak file & its size is 1311 kb, but when I get to the location(thru palm import) in the folder tree where it's supposed to be, the only datebook file there is labeled "unfiled.dba" and is only 640 kb. I tried importing that but didn't get back any lost data.
    Is there another way you were thinking I could "import"? Thank you for your help. Janette

Time Machine Deletes Old Backups without warning!!

I have just lost loads of pictures and emails when my Timemachine deleted old backups. I was so happy to have an easy way to keep my iPhoto cleaned up while keeping all the photos for the future. I would load my all the photos from my camera, backup with TimeMachine and delete the "bad" unwanted photos, confident in the knowledge that these pictures are still there on my external. I looked forward to some future date when someone would write an easy piece of software to consolidate old iPhoto libraries and even go through TimeMachine and consolidate those photos too. But until that fantasy event, my pictures, even though not wanted were still there.
Not any more!!
I replaced my hard drive and reloaded my laptop from Timemachine and I think that was the event that sparked the dump.
There should be a special check box to make sure that NO backups are automatically deleted, EVER. They should be a way to make them Sacred!!
There should be a way to create a separate backup just for iPhoto because right now, there are no good ways to easily break apart or merge iPhoto libraries. At least what I was doing worked, (well.... until it didn't).
Any ideas??

True, TM is not a classic archival system, but until the drive is full, the difference is moot.
No, the difference isn't moot.
I still have on my TM HD every file I ever had because it's only 1/2 full.
No, you don't. Read on...
Time machine has three levels of backups:
1) hourly - deleted after 24 hours
2) daily - deleted after a week
3) weekly - deleted only when the disk is full - these are the only deletions you will be warned about
Time machine is always deleting files. Every time it backs up, it deletes files.
But the OP's real question is why he was never warned about the old backups being deleted, as TM says it will do, archival stuff notwithstanding. Apparently TM simply ignores the user's request to be warned.
No, it doesn't.
That being said, as I asked in a post not too long ago, "how many have had a warning from TM that old backups are being deleted?" as one would expect when the TM preference box, "Warn when old backups are deleted" is checked.
It appears to me to be a bug.
I ask again if anyone has gotten this warning.
Nobody answered my previous post with a yes.
Yes.
Because Time Machine continually cleans up behind itself, it tries very hard to ever delete the weekly backups. The only time I've gotten the deletion warning was when my disk was full. I think I just avoided the problem by removing my old Parallels images from Time Machine and got back an extra 70 gig or so - good for another six months.
This is not a bug. This is how Time Machine works. It is unfortunate that the original poster did not fully understand this. The fact is that Time Machine backs everything up. If you create 100 files, it backs up the folder with 100 new files. If you delete 100 files, it backs up the folder with 100 less files. Then, the next day, it deletes old backups. The only one it keeps is the last one, with 100 less files.
It is correct to say that Time Machine is not an archival system. It is a backup system. If you want to save your files forever, you need to copy them to a location that isn't under the control of any sort of automatic software.

Time machine bug after upgrading system

Hello,
I just upgraded my macbook pro from Lion to Mountain Lion.
After this upgrade, I created a new admin account and tried to install back my previous account with my entire files thanks to migration assistant with a time machine data.
Unfortunately, it seems that my 150go of personal data are in my hard drive after time machine'work but I can see my last account with my entire file. I have just the choice to loggin to my new ML admin account. Moreover, I can use some application with this new account but the fact is that I can found my important files.
Do you have any solution in order to find my previous account?
Thank you,
Regards,
Niels.

See the pink box in Problems after using Migration Assistant for an explanation. One of the workarounds in the green box (probably #4) should set things right.
