This article explains how to schedule backup jobs in Backup4all. A scheduler can be set for a backup to be executed automatically at certain time intervals (daily, weekly, monthly) or at system startup, logon, when idle or shutdown.
You can schedule a backup either from the Backup Properties window or from the Schedulers window. The difference between the two methods is that the first displays the scheduled tasks only for the selected backup job, while the second will show you the scheduled tasks for all the backup jobs and tags.
If your computer was turned off during the backup time, the scheduled backups won't run. In this case, a solution is to configure the scheduler to start the backup as soon as possible after a scheduled start is missed.
