Config:
Disk A: Boot disk
Disk B: backup disk

I have written an Applescript which copies my Disk A important database documents to Disk B (keeping all different daily versions of my work).

I would like to clone/synchronize Disk A on Disk B, so that I can boot safely from Disk B, if needed.
So, I must first copy Disk B backup folders, to disk A avoiding those folders to be erased when cloning Disk A
I have written an Applescript to perform it.
Then I would like this script to launch SD and make it:
- Repair permissions on Disk A
- Smart update Disk B from Disk A
- Quit

Is it possible ?
How ?

Thanks to help me.
