Okay, so I currently have a full Time Machine backup of roughly 3tb, however, I'm currently planning a clean install on my machine and will be changing my file structure; for example, currently I have two separate volumes (Mac OS & Users, Files) that I will be combining into a single volume. What I'm wondering is how Time Machine will cope with this? I'll likely restore from backup manually, as I'll never be able to leave my machine on long enough to copy everything in a single day, but I want to make sure that when I do copy everything that I can start backing up again where I left off, without having to do a full backup. I'm not sure however what support Time Machine has for this, for example, can I use the Terminal to change hard-link targets so that my backup (roughly) mirrors the new structure, for example, I would move the contents of the Files volume backup into the same folder as my Mac OS & Users backup, then rename to match the new volume, all within the latest backup. If this is possible then how do I go about doing it, and is there anything I will need to avoid doing? I know Time Machine somehow applies strange permissions to a backup volume that prevent most tampering. Are there any tools for doing anything like this automatically; e.g - to just scan my machine and move my backup around until it matches?
