policy directive all local drives and selected C,D drive set difference

Dear Forum,

1. I have an ms windows policy with C and D drive + system state backup selected (the two drives are local not network drives)
2. I also have an other ms windows policy with ALL_LOCAL_DRIVES directive selected
Is there any difference in terms of backup and restoration?

I read the manual and it says that all local drives directive contains system state as well and backup the local drives.
If I restore 1. numbered backup or 2. numbered backup are they work the same way?

ps: I set the 1. the C and D with streaming to backup concurently. I only see that this is the only difference.

I am looking for you answers

thank you in advance

regards

Karoly
