Schedule Backup Task If Manual backup is selected, users must start each backup task themselves. Scheduled backups can be set to run on an hourly, daily, or weekly basis. If you do not want tasks to run when your IT infrastructure is being heavily used, you can select Configure Backup Windows and specify time slots for when the backup task is allowed to run. Select a Retention Policy Users can choose to store all versions of their backup, limit the number of stored versions, or keep only certain versions according to a schedule. You can choose to set rules for keeping backup versions, such as to retain the latest version of each day, week, month, or year. You can edit the retention policy at Active Backup for Business > Physical Server > Task List > select the task > Edit > Retention > Advanced retention policy > Set Rules. Selecting the Keep only the latest ... versions option will store a set number of versions regardless of the time intervals set. If more than one backup version exists within a certain time range, only the latest one will be kept. For example, if you set a policy as Keep the latest version of the day for 1 day for a backup task that will run every hour, only the version backed up at 23:00 will be kept. A version can meet more than one retention rule at a time. For example, a version can be retained by the weekly retention rule and daily retention rule at the same time. Advanced retention policy employs the GFS, or Grandfather-Father-Son retention mechanism. Backup Configuration 10
