Does Time Machine use internet? I'm not very computer savvy. I recently got my MacBook back after getting a new hard drive. I've now just starting using Time Machine to back up everything. I live in rural Texas and I only have 10 GB of satellite internet data to use each month and I've used it all in 2 days while barely using the internet. 

Does Time Machine use data? If not, any ideas on what could be eating all of my data up? My Wi-Fi is secure, even if it wasn't there is no one around to use it anyway.
Time Machine does not use the internet, but iCloud does. If you use an iPhone or iPad, iCloud will backup the images to iPhoto, and that can use significant bandwidth. 

Calendar, Mail, Contacts, Messages, Notifications, Twitter, etc all use bandwidth, and all are on by default. iCloud will also backup your documents and data, if you have configured this. If you have more than 10GB of files in your Documents folder, iCloud could be simply backing them up from the new hard drive.
