Conditional folder backup option

[kaizokou]

Hello, thanks for the bundle, it's good job.

I haven't find anywhere in the doc if there is an option for conditional folder backup.

there is the folder option in the config :
folders: [ web/uploads , other/folder ]

It's working fine, but I don't alway want to save all my images as this is a big folder specialy with Capifony
Is there a way to do this ? Maybe as a command line parameter ?

Thx.
