Managing backups

Hi,

Spent a few hours reading help, support forums and internet.
Still could get only half way through.

Here is what I'm trying to accomplish:

1) Folder A contains:
original_file.txt
Backups (directory)

2) Backups folder contains:
"<time-stamp> 1 original_file.txt"
"<time-stamp> 2 original_file.txt"
Backups were made manually

3) Backup logic:
a. look into folder Backups and see if all files were added more than 2hr ago
b. copy "original_file.txt" from folder A into Backups folder and rename with time-stamp.

I am able to traverse folder structure and get to 3a. What I'm struggling with is how to execute 3b.
This seems to be going against my interpretation of Hazel logic "watch file/folder and act on it", as i''m trying to accomplish "watch file, act on another".

Which logic should I follow to get this backup approach to work?

thank you,
Dmitry

I think a script is the only way to do this since it involved an unrelated file.
