Can I choose how many Time Machine backups I want?

    When you partition your 3 TB drive into a 500 GB Time Machine volume, it isn't 3 TB anymore. Unless your startup drive is 180 GB or smaller, that 500 GB drive is too small. All of those extra backups that Time Machine makes take up very little space. Time Machine can properly manage the backups and delete old ones if it runs out of space. But it needs a certain minimum amount of room to work.

     

    Time Machine is designed to set and forget. Those who ignore its requirements and try to control how it works always have problems like the ones you describe. If you think you can do a better job of backups than the engineers at Apple, then youbshould really use SuperDuper! or Carbon Copy Cloner instead.

    It sounds like you have a backup drive that is too small and that you are storing other files on it in addition to Time Machine. Both are virtually guaranteed to cause the problems you descibe. Time Machine needs to have space to work and you aren't giving it the space it needs. External drives are very inexpensive. I suggest getting a new one. There is really no other option.

     

    Sorry, but what you're saying is just wrong.

    Etresoft is in fact, right, you are wrong.

     

    You are trying to make Time Machine operate in a way it was not designed to and your TM drive is far too small. Fix point 2 and allow TM to run as it is supposed to or use something else.

    Then explain please...

     

    It is not running "the way it was designed to" at all, in fact the way I'm trying to use it is the way it was designed to work: by deleting old backups. And this is exactly what time machine does, because everyone will reach the point when their backup hard drive will be full, and then time machine will start to delete the backups. And this is exactly what I'm doing, but apparently it isn't working.

    Have it your way then.

    Time Machine is a pretty typical Apple product. It is designed to work best by just plugging it in. The more you mess with it, the more trouble you will have. If you want a solution where you can ignore the recommended configurations, tweak all the settings, and have it work perfectly, then you will have to look elsewhere.
