Under Choose A Day And Time, you can designate the days and time a backup should occur. (Since I want to perform a daily backup, the On pop-up menu is blank.)
Click OK when you've finished customizing the settings. If you want to add another destination, click on the plus-sign (+) button under the Destination And Schedule section. If you want to delete a destination, select it and click on the minus-sign (-) button.
Step 4: Perform a backup
If you still have the backup-plan window open, you can click Back Up Now to perform a backup immediately. Subsequent backups will occur at the scheduled times.
You can also perform a backup in the Backup window, which is the window that appears whenever you launch the software. Select the backup plan in the window, and click on Back Up to start a back up. The first backup will take a while, because it needs to copy all the designated files over.
