In the help for Acronis TI 10 Home under Backup Policy, it says the following: Create differential backups - having chosen this parameter, check the Create a new full backup after ... parameter and specify number of differential backups, after which a new full backup will be created. The first time a full backup will be created. Next backups will be differential until the specified number of differential backups is reached. Then, again a full backup and a set of subsequent differential backups is created, then again a full backup and so on. I cannot find the bolded parameter above on the setting up a task screens. Can someone please point out what I'm missing.
