More Control over Time Machine

Unless you tell it otherwise, Time Machine backs your Mac up every hour.
You might find that to be too often or—if you’re working on important stuff not often enough. Fortunately, with a text editor and a little determination, you can change that interval.

Navigate to: your hard drive/System/Library/LaunchDaemons/com.apple.backupd-auto.plist
Copy that file, and then open it with a text editor. The file isn’t long so you
won’t have any problem finding the line that reads:
<integer>3600</integer>
3600 is the number of seconds betwixt backups, so increase or decrease that number until the interval seems ideal to you. Replace the original file with the edited version you just created, and Time Machine will back up according to your schedule!
