[1.7.10] A good approach for a backup mod

[Is.M.L]

I want to write my own backup mod to my own server. Because the host has a terrible FTP server, downloading a zip file and uploading the world folder back is not an option for me. My idea of my own backup system would be to save the world seed, and to save the state of each player periodically, and ignore the chunks. Then I could explicitly add a chunk to the backup system and have it saved too.

How can I implement that:

How can I access a list of all players and save them? how can I later load what I saved?
How can I access the data about one particular chunk and reload it if needed? Does this data contain all entities and tile entities in the chunk (EntityItem, EntityLiving and TileEntity)? Can I write the saved data to a live chunk?

It really doesn't make any sense saving individual chunks and your going to end up running into a lot of issues.
