Copying files for backing up my plugin

[zodiac7]

Hi,

We have a confluence plugin which we want to take a backup of.

The plugin (a confluence theme) has been developed in-house using the Atlassian SDK and Java and running on confluence version 5.5.2 on premise.

Can you please tell us:

1. What is the procedure for taking a backup of this plugin
2. which directory(s) the plugin is copied 
3. What files we need to copy to be able to "revert" back to this version of the plugin
4. What is the procedure for going back to this version of the plugin

Thanks,

Deepak.
