Mirror without deleting right orphans?

[toweyb]

Hi, folks, I have a script that needs help.

Right= 1000+ XML files exported from a complex system. They all have the original export date.
Left= The same files, exported today. They all have today's date. Most are unchanged. Some may be new (left orphans).
Goal: Copy left orphans and binary differences to the right BUT don't delete the right orphans.

What I tried:
Sync Update only copies the left orphans, not the differences. That's not what I need.
Sync Mirror deletes the right orphans. That's not OK either.
Move left->right doesn't seem to do anything. Maybe I don't have the right selection.

What's the proper way to copy only the selected new and different files from left to right?

Here's a script that runs a binary comparison, then copies files that only exist on the left (orphans) and files with binary differences from left to right.

log verbose c:\log.txt
criteria binary
load c:\today c:\original
expand all
select left.orphan.files left.diff.files
copy left->right

Perfect, thanks!
