    i am having a minor problem with TM and hopefully someone can help me

    i use 1 external tb to back up everything

    i back up about 725 gb if stuff and when i go to run my TM it tells me i only have 150 or so GB of space to back up the aforementioned 725gb.

    Maybe i misunderstood TM, but cant i back up multiple days without using the same size of backup? i.e. i back up january 1st, december 1st and november 1st and it wont need 2.175 TB of space?

    i hope that makes sense

    thanks for any help!

    Hi
    I had a similar issue a few days ago, although i backup to a 500GB drive. Long story short, i could not find a solution and resulted in re-formatting the backup drive and starting over. But i realize this may not be a viable option for some people.
    However, it seems to have solved the issue, and so far it has been backing up fine.
    It is a strange issue, as previously it would just 'add' to the previous backup, but recently it wants to completely backup the whole system.

    Hopefully someone has a better idea as to why this is happening?
