Ok makes sense.
This is what i have done.
I had a file made in the home folder (say: cm docs folder) where the files are in that i wanted to be encrypted i guess this is what you mean.
With Grsync i made a copy of the whole home folder with all regular folders in them incl. the cm docs folder.
What i dont understand is the custom mount point option
If i understand i correctly its not needed when doing a backup of home folder as the (cm folder) was included in that backup and was encryped as with caja i can enter it, but its all encrypted which is what the intention was in the 1ste place.
