Time Machine overwrites older backup data, right?
I am backing up a 1tb iMac and a 2TB media drive (external USB) to a 9TB DROBO FS. For those not familiar with the Drobo, it is basically a NAS with some other features.
My question is: The Drobo is telling me that one of my disks is full. It is my understanding that Time Machine, when encountering a "full" backup destination that it would overwrite the oldest files the the more recent ones. Time Machine is telling me that it hasn't backed up in two weeks because the disk is full.
Thoughts? Either with Time Machine, or if you are familiar with a Drobo.
Thanks.
Oh. iMac, Mavericks.
