On the New Backup screen you are supposed to define all the parameters of the backup operation.
In the Backup Description section, enter any commentary you think can be practical for further backup operations.
The Exclude section allows you to keep certain files and directories from backing up:
Warning! If you exclude one or more system or hidden files/folders from the Container backup (e.g. either the Hidden files or System files checkbox is selected), you'll be able to restore only separate files from this backup, but not the Container as a whole.
The Include section allows you to limit the backup process with a number of selected files or directories inside the Container. In the field provided, type the absolute path to the file or directory you wish to back up. To include additional files or directories, click the plus icon to the right of an existing path and enter a new path.
The backup will contain only those files and directories that you have indicated in the Include section. To back up the whole Container, leave the Include section empty.
