(Disclaimer: first time using GitHub for anything other than downloading)
This is just a suggestion

Where "delay:60" is for global backup delay, this should be per "backup-list" > "path", this way someone could, for example;

• Backup their world files and logs per hour
• Backup their plugin files and config files (everything large/ changes less often) per day or week

Edit: GREAT plugin by the way, worked first time, drag and drop into server and change config, works great.

I think this may be hard to implement because the code architecture would need to be restructured. I'll look into this maybe next week or so but I can't promise anything.
