Backup jobs scheduling optimization

摘要

Scheduling of backup jobs is optimized in accordance with a characteristic of the backup jobs. The characteristic of the backup jobs can take into account a number of the backup jobs that are stale. A stale backup job is a backup job in which no backed up data changed during a most recent performance of the backup job.

1. A method comprising, by a processor:
determining a number of stale backup jobs of a plurality of backup jobs, a stale backup job being a backup job in which no backed up data changed during a most recent performance of the backup job, each backup job being one of an incremental backup job and a full backup job; determining a percentage of the stale backup jobs that failed to execute successfully during the most recent performance thereof; assigning a highest rank to the backup jobs that are incremental and the percentage of the stale backup jobs that failed to execute successfully is 100%; assigning a second highest rank to the backup jobs that are full and the percentage is 100%; assigning a third highest rank to the backup jobs that are incremental and the percentage is greater than 0% and less than 100%; assigning a fourth highest rank to the backup jobs that are full and the percentage is greater than 0% and less than 100%; assigning a second lowest rank to the backup jobs that are incremental and the percentage is 0%; and assigning a lowest rank to the backup jobs that are full and the percentage is 0%; and optimizing scheduling of the backup jobs in accordance with the rank of the backup jobs.
