rsync time machine backup permissions

[Joe]

I'm not sure if this might be an issue here. Since your variable isn't 
quoted, it might not be. But:

When you run rsync as rsync $param1 ...

and param1 is null, it may still be treated as the first argument to 
rsync - which may add the current directory to your sources or throw 
things off in some other way.

It depends on if it gets eliminated by the shell before rsync sees it.

Since this is relatively invisible, it's pretty hard to notice.

See 
https://unix.stackexchange.com/questions/415990/how-can-i-expand-a-quoted-variable-to-nothing-if-its-empty/ 


for a detailed exploration of this problem and ways to avoid it.
