I work from home and the Time Machine backup is kicking in way too often. If I could set it to backup later in the day, that would be great. Any suggestions?
You can turn Time Machine off. Set it to show TM status in the menu bar. Then, when you want it to back up, click on TM's menu item in the menu bar and chose Back Up Now. Unless you really need hourly backups, this way you can initiate the process when you know it's necessary.
