I have been running time machine flawlessly for a while.  However, on April 26, I created a new user account.  I dragged a very large file (clone of a different computer and time machine backup of a different computer) to that user desktop.  Those files were previously being excluded from backups.  Apparently, wehn I moved them to the new user it tried to include them and I got a warning about the External Drive not being large enough for the backups.  I sorted out excluding that user completely but now I can not access any backups prior to the new user being created.  Are they lost forever?  Did it delete the External Drive to try to make room for the backup?  I would think that it would have to check the size before it even does any deleting and then if it knew the backup was too big it wouldn't delete and it would just abort the backup.  Can anyone help?  When I enter into time machine the last backup shown is April 26, when I browse the drive the oldest folder is April 26 and when I look at the time machine menu it says the oldest backup is April 26.

 

I am using an iMac with Snow Leopard installed.


Also, I tried looking at the logs in the console but I could not seem to go back far enough.

    Try rebooting. Sometimes, when you have multiple users, the Time Machine drives get confused and get mounted under the wrong names.

    the computer has been restarted several times and the disk has been ejected multiple times as well.

    Are you going into Time Machine from the old user? If you enter Time Machine from the new user, you won't see any files created before that user existed.

     

    You can manually go into your Time Machine volume from the Finder, just to verify that your backups are all there. Don't make any changes in the Finder. Even if Time Machine's "starfield" interface isn't functional, you could still restore files manually if you had to. If Time Machine is really confused, best option is usually to just erase the Time Machine drive and start a fresh one.

    I have looked at the drive through finder and I have entered time machine with both users.  Nothing older than April 26 anywhere.

     

    I don't get why TM would delete everything before it verified that the data would actually fit even if everything was deleted.

    I guess the details are in what that warning actually said. Time Machine will delete older backups to make room for new data. If you suddenly double or triple the amount of data to be backed up, and tell it to go ahead after being warned about something, it will do what you ask. You still have a backup, just not the historical versions. Time Machine doesn't know what you meant for it to do, it only does what you ask it to do. It provides a backup and apparently still fulfills that mission.
