Sorry for the awkward wording. I've been using an external for my Time Machine backups, and I recently clean installed Mavericks. I don't want to restore my old data via TM, I'm only going to grab files from my backup as I need them. Can I use that same external to start new Time Machine backups? Will it delete everything? In my situation what would be the best way to approach this? I have other Hard Drives that are smaller, but I would like to use my big one. Also, can I delete old Time Machine Backups on the drive, and just keep the newest one? Or are they all linked together or something? For each backup that TM makes, they are about 500GB, and I have about 8 of them in a 2TB drive. How is that possible? Does this mean they are somehow linked together?
