Currently all my Time Machine backups are on the same Hard Drive where I store all kinds of other stuff. The backups are starting to max out the drive so I plan on buying a new seperate external strictly for backups.


What I want to know is: when I choose the new drive for my backups and do the first initial backup, will that unlock all the other ones on my old drive for deletion?

    I'm not sure if I have understood your question. In Mountain Lion, when you use another disk for Time Machine, Time Machine will backup on both your external hard disks and it will only delete backups on your older disk if it hasn't got space

    If you want to save your old backup and continue to use it, you should be able to copy it from your current external hard drive to a new one. You can then reset Time Machine in System Preferences to look at the new drive. I have done this several times as I have rearranged external hard drives.


    If you just want to delete your current backup, you should be able to do that also.

    To erase the whole drive, open Disk Utility and erase that disk. Check >

    Get the new external drive. Copy the files you want to keep from your current drive to the new external. Erase the old drive. Move the files back to the old drive. Run Time Machine on the new drive.
