This may be a frivolous question, but I'll ask it nonetheless. I now use an external USB HDD to save my backup images to. I'm wondering a couple of things: 1) Can I delete all the incremental images, saving just the initial full backup and then continue with the incremental images? 2) Can I simply delete all the backup images and begin over with a full image and then the sequential incremental images? Which would be the preferred thing to do? Thanks!
