    This may not be an actual bug; there may be some sort of problem on your installation of OSX --  I do a lot of testing, including beta testing, and haven't see this behavior, and haven't seen it reported elsewhere.  You might try reinstalling OSX (that won't disturb anything else).

     

     

    Also, I suspect it's not using the datestamps in the name of the backup folder.

     

    Each backup folder has several extended attributes, including both the start and completion dates.  Those aren't in recognizable text form, but in the special format that most dates are carried in on UNIX systems -- the number of seconds since January 1, 1970 (I think), in the GMT zone.   For any display purposes, that value is converted to your current time zone and DST setting.

    Thank you for the advice, although at first sight that doesn't seem without risk! Of course, I've never done an OSX reinstallation! Could you point to some page with instructions? Thank you very much!

     

    Regarding the extended attributes, I suppose you're talking about the .Backup.log files.

    Oh, sorry, you sounded fairly experienced.   It's not a big deal, since it just replaces your existing copy of OSX with a fresh one.  See the pink box in Installing the ''combo'' update and/or Reinstalling OSX.

     

     

    Regarding the extended attributes, I suppose you're talking about the .Backup.log files.

    No, the actual backup folders on the TM drive (inside the Backups.backupdb folder).  That's where Time Machine stores various "extra" information about the backup source, etc.  For example, it uses fixed identifiers for the Mac and disk(s) that were backed-up, so you can rename them (or even have duplicate names), but OSX and Time Machine still know which is which.  If you change your Mac's name, or the name of any drive or partition that's being backed-up, Time Machine will automatically change those folder names correspondingly.

     

    Some of those are mentioned in the green box in How Time Machine works its Magic.

    Thanks for the advice. I'd like to see a step-by-step explanation for both reinstalling OSX and combo installation (my original OS was 10.6.4, but now is 10.6.8) before adventuring... (Besides, I suppose that in your box for Mountain Lion you mean it where you wrote just "Lion Install disc").

     

    OK, I've seen those xattr's, thanks!

     

    Besides, here is a new suspicious deletion:

    Nov  7 00:09:55 iMac com.apple.backupd[30981]: Backup completed successfully.

     

    This time, I think that it may be related to DST hour change: maybe Time Machine (in spite of having access to the exact start and completion times) is somehow seeing the backup in red as if it were created one hour before (well, somehow it actually was!), that is, as if it were created before midnight on Oct 8, which lies one day beyond the 30-day limit from Nov 7. Anyway, I think it should have been kept for one more day, because it actually was the daily backup for Oct 9.

     

    That can also be applied to 2012-10-04-000909, which was deleted on Nov 2, as shown in an earlier post.

    Sounds like your backup drive isn't large enough so Time Machine starts removing old backups to make room for new ones. How large is your backup drive? How much space is used on your hard drive and how much is available?

     

    About TM "Backup Drive is Full"

     

    Alert TM only deletes older files if they have been deleted from the source and when TM needs space on the backup drive for a new incremental backup. Time Machine "thins" it's backups; hourly backups over 24 hours old, except the first of the day; those "daily" backups over 30 days old, except the first of the week. The weeklies are kept as long as there's room.

     

    So, how long a backup file remains depends on how long it was on your Mac before being deleted, assuming you do at least one backup per day. If it was there for at least 24 hours, it will be kept for at least a month. If it was there for at least a week, it will be kept as long as there's room.

     

    Note, that on a Time Capsule the sparsebundle grows in size as needed, but doesn't shrink. Thus, from the user's view of the TC it appears that no space has been freed, although there may be space in the sparsebundle.

     

    Once TM has found it cannot free up enough space for a new backup it reports the disk is full. You can either erase the backup drive and start your backups anew or replace the drive with a larger drive.

    Yes, the REINSTALLING OSX section of the pink box in Installing the ''combo'' update and/or Reinstalling OSX covers installing a fresh copy of OSX from your Snow Leopard Install disk, then details that you'll probably need to either install the "combo" update (as covered in the "COMBO" UPDATE section, or use Software Update).

     

     

    (Besides, I suppose that in your box for Mountain Lion you mean it where you wrote just "Lion Install disc").

    Yes, I just corrected that -- thanks!

     

    Besides, here is a new suspicious deletion:

     

    If the problem is in your installation of OSX, I'd not be surprised for them to continue until you install a fresh version.

    Hi, Kappy,

     

    That's not the problem here -- as detailed in the earlier posts, Time Machine is doing normal "thinning" (and the drive is not full), but it's deleting some backups earlier than it should -- some "hourly" backups are being deleted when 23 hours old, not 24; and some "weekly" ones seem to be deleted when they shouldn't.

     

    Since this doesn't seem to be affecting anyone else, we're suspecting there's something wrong with the installation of OSX that's affecting the date calculations, so are going to try a fresh copy of OSX.

    Just to summarize. The backup volume (a partition on an external FireWire 2 TB disc) has 1.2 TB, from which 167 GB are available, and the Mac HD volume (a partition on an internal 500 GB disc) being backed up has 468 GB, from which 165 GB are available.

     

    However, my Time Machine has never reached a "disc full" condition: all the deletions have taken place at the post-backup thinning phase. The point of the whole discussion is that Time Machine is irregularly deleting backups too soon. Pondini thinks that I should try reinstalling the OS.

    There are a number of them.  See the green box in Time Machine - Frequently Asked Question #27 for a few suggestions.  Note that none of them are perfect.

     

    The most common alternatives make "clones," very different from Time Machine backups.  See Time Machine vs. Clones and Archives for a general overview of the different types of backup apps, and the advantages and disadvantages of each.

    Thank you again, Pondini.  In fact, I've been following your advice on using two different ways for backing up, that's why I use SuperDuper in addition to Time Machine.

     

    Just for the record, returning to the unexpected deletion of daily backups (red) that begun on Nov 7, it has lasted four days. Note that sometimes they take place even a little below 29x24 hours.

    The next "midnight" backup took much more time than usual because SuperDuper was working, and Time Machine waited for an hour repeating Waiting for index to be ready (100), and it had to backup more data than usual (see below):

    Finally, because of a problem with my phone 16GB SD card, I wanted to restore its data by combining manual backups made on several iMac folders, the last one a couple of days ago. As you know, the DST hour change affects the datestamps in the Mac (HFS), but not in the SD (FAT), so I changed the iMac timezone to compensate for the hour change while saving the last SD state before reformatting it (in order to make datestamps comparable with previous backups), and also when restoring the pre-hour-change backup data (in order to restore the SD to the original timestamps). The two first deletions shown below correspond to current timezone + 1 hour (i.e., the "real" times were 20:47 and 21:44). The curious stuff is that Time Machine decided to delete a  backup from Oct 26 that it could have deleted a long time ago.

    After these timezone changes, I've bee able to verify that the CompletionDate extended attribute correspond (after DST correction) to the backup filenames.

    Do you have any other problems with similar date calculations, such as Mail deleting messages at a certain age, anything with iCal, etc.?

     

    Have you tried installing a fresh copy of OSX?   Something damaged or missing in the version on your Mac seems the most likely culprit to me.

    Not using Mail (but Thunderbird) or iCal (but my phone's agenda). I can't think where else could I watch for some time calculation glitches...

    I really appreciate your suggestion and diagnosis, I'll try to learn more about that procedure and its risks. This is my first Mac, and I like Time Machine, one can feel calm of being able to recover past versions of files (with probability decreasing with their age), if not for those irregular deletions.

    I should have said that all were a little more than 29x24 hours old, since they were one hour older than they may seem at first sight, because of the DST hour change that took place on past Oct 28.

     

    I can also confirm that the backups (green) that took place within the periods of time where the machine timezone was changed to +1 hour, have been deleted past the 24-(real)hour limit, even if their filenames indicate otherwise:

    ejtrim Level 1 Level 1 (0 points)

    I've just seen a bulk of 13 "unexpected" backup deletions by Time Machine, this time because of a disk-full condition that shouldn't have happened.

     

    Just prior to these deletions I had simply moved with the mouse on Finder several large directories into another just created directory.  I had understood that Time Machine made hardlinks on directories, and thus this simple movement should only cost a few bytes of hardlinks in my backup disk.  However, with TimeTracker I've seen that these directories (summing up 123GB) have been fully copied, thus they are twice on my backup disk.  That large space "needs" have provoked the deletion of the 13 oldest backups (3 full months) that should have been kept until a "real" disk-full condition.  Here is the log:
