With the Manual start scheme, you do not have to specify the backup schedule. You can run the backup plan from the Plans and Tasks view manually at any time afterwards.
Specify the appropriate settings as follows.
Backup type
Select the type of backup
Full - selected by default for all backup locations (except for Acronis Online Backup Storage).
Incremental. At the first time a full backup will be created. The next backups will be incremental. Selected as the one and only backup type for Acronis Online Backup Storage.
Differential. At the first time a full backup will be created. The next backups will be differential.
