This method allows for you to run regular snapshots that will check for any new or changed files to backup throughout the day, rather than at a specified backup schedule time.
Login to the backup client, select "Backup Sets" and select the set in question.
If you are on the Business client select "Continuous Backup" on the left, on the right you will then be able to toggle it on and set requirements as you see fit.
If you are on the Single User Client you will need to select "Others" on the left and then on the right you will be able to toggle on "Continuous Backup" and set the requirements to how you see fit.
PLEASE NOTE: the backup will not run if no new or modified files are found.
