Profiles are files that contain textual information about a backup. You do not have to use profiles to use the program. Profiles can be used to save frequently performed types of backups. The default profile is used to initially start the program and provide basic backup information.
Backup information, such as backup type, files to backup, and files to exclude, can be changed and this information can then be saved in a new profile by using the Save As menu item.
Once a profile is saved it can be loaded from the Profile > Load menu item and then run with or without any further modifications.
