Please help me understand which settings I need.

[TMBGeeks]

I have 2 pretty basic syncs that I want to set up but I'm getting thoroughly confused and want to be 100% sure I'm doing it the proper way; could anyone please tell me what settings I'm wanting? I've watched every video and read the articles.

My setup:
Drive X = Commonly Used Files
Drive A = Full Backup
Drive B = Full Backup Copy

I want to edit, rename, move, create, and delete folders & files on X, then once a week I'll use the files on X to update A. After that, I'll do a second sync to use the files on A to update B or simply run the first sync again w/ B as the target this time.

Note: I want edited, renamed, and moved items on X to be updated on A (and likewise from A to B), not deleted and new copies created. If I'm not mistaken, this will minimize wear on my drives.
