CA VM:Backup system administrators and operators submit backup jobs as scheduled or as needed. The backup data protection required by your data center determines the interval between backups. Your restore needs determine the backup schedule best suited for your site.
If a week-old copy is adequate for a file, weekly backups may suffice. The most common schedule is to run a full backup once a week, an incremental backup daily, and a backup of CA VM:Backup daily. A full backup each month with a longer tape retention period may serve for long-term backups. If you use a scheduler system (for example, CA VM:Schedule ), you can schedule jobs to run at preset times or you can use the VMBCYC task to break out your backup schedule over a full week. For information about VMBCYC, see the CA VM:Manager Automated Implementation and Control Guide.
One reason to run frequent full backups is to avoid problems that can arise from maintaining long catalog chains. For example, if you need to restore a full minidisk and you have not run a full backup for several months, you may have to mount several months worth of backup tapes before the most recent version of that minidisk can be restored. To ensure that your restore needs are met efficiently, you should run a full backup at least once a month.
