You can set an Intronis Backup policy to run with an existing execution schedule, or you can override the execution schedule to run the policy at a different time.
Allow To Finish
Allow To Finish is an option for File and Folder policies only. It lets backups finish once they have started, no matter the schedule. If you choose not to enable the Allow To Finish button, Intronis Backups that use an execution schedule end when the schedule window ends, even if the backup is not complete.
When you enable Allow To Finish, backups always complete, even if they have to continue outside the maintenance window.
