Time machine doesn't do what it's supposed to.

I have 670GB of data to back up. My backup drive has 698GB of space.



Right now, it's telling me that it can't back up because there isn't enough room. There is only a total of 670GB of data, so it should be able to make room by deleting older backups, right? Isn't that what it's supposed to do? Delete older backups when there's no longer room to keep them?

    Not really, Time Machine is designed to keep a track of your files over time... which means it takes up more space than a typical backup.



    Go grab Carbon Copy Cloner and just image your entire drive to your backup.

    You need to have at least 10-20% extra free space above what is to be backed up as it uses this free space for temp files during the backup process.



    The post above may well help I am nit 100% sure as I haven't tried for a while but it did work well the last time I used it.
