	Yes.

	Yes, although instead of HLock and HUnlock, use:

	oldState= HGetState(Handle(SELF));
	MoveHHi(Handle(SELF));
	HLock(Handle(SELF));
	{ stuff here }
	HSetState(Handle(SELF), oldState);

This will allow you to do this trick across multiple routine calls.

	No; DiskFit won't preserve the file and folder permissions.
Retrospect will, and I use it in an automatic mode to back up a file
server in the middle of the night to a tape drive, without having to
shut down the server. (I have no relation to Dantz Development except
as a satisfied customer.) Retrospect does lots of other nice things
besides, and it's a little over half the cost of Network Diskfit.
