How job scheduling works in Backup Exec
Backup Exec lets you configure the time and the frequency for which you want to run backup jobs. You can run jobs immediately, once on a specific day and time, or more than once according to a schedule. Backup Exec lets you use minutes, hours, days, weeks, months, or years as measurements of time to create a recurring pattern for the schedule. Alternatively, you can select specific days of the month to create a recurring schedule on which jobs should run.

Availability window
Backup Exec has additional scheduling options that you can use to ensure that the job does not run outside of your availability window. The availability window is the time range when your backup sources are available to be backed up. You can configure how long you want an incomplete job to remain scheduled before Backup Exec reschedules the job and changes its completion status to Missed. You can also configure the job to automatically be canceled if it is running for too long after its scheduled start time. These options help ensure that backup jobs do not affect your system resources during critical hours.
Scheduling conflicts
Backup Exec resolves scheduling conflicts between two backup jobs by running the less common job and skipping the more common job. If a full backup job and an incremental or differential backup job are scheduled to run at the same time, Backup Exec runs the full backup. The incremental backup or differential backup is skipped and it runs again at its next scheduled time. Full backup jobs always supersede incremental and differential backup jobs. If two backup jobs of the same type are scheduled to run at the same time, Backup Exec runs the less frequently scheduled job. The more frequently scheduled job is skipped. The skipped backup job runs again at its next scheduled time. For example, if a monthly job and a daily job are scheduled to run at the same time, Backup Exec runs the monthly job. The daily job is skipped and it runs on the following day per its normal schedule.
Including and excluding dates
The Exclude Dates option lets you exclude specific dates from the schedule. For example, you can exclude holidays from your normal backup schedule.
You can use the Include Dates option to include dates with your backup schedule. When you include a date with your backup schedule, the backup job runs on the included date, even if it is not normally scheduled to run on that date. You may want to schedule an include date to run an extra backup job, outside of the job's normal schedule.
