Best practices for Backup Exec data lifecycle management (DLM)
Best practices include tips and recommendations to allow the most efficient use for the Veritas Backup Exec data lifecycle management (DLM) feature. You should also review the best practices for the agents, options, or other features that you use.
For more information about DLM, see the Backup Exec Administrator's Guide.
The following best practices are for efficient DLM:
To prevent DLM from deleting an expired backup set, you can manually retain the backup set or you can change the expiration date of the backup set. Backup Exec automatically retains all dependent backup sets as well. When you no longer want to retain a backup set, you must release it so that DLM can delete it.
To prevent the inadvertent loss of backup sets when you enable the option 'Allow Backup Exec to delete all expired backup sets', do the following:
Ensure that when you create jobs, the backup sets are kept longer than the amount of time between full backups. Otherwise, the backup sets from the last full backup job may expire before the next full backup runs.
Ensure that you rerun failed or missed jobs before the backup sets from the previous full backup expire.
When setting up the schedules for backups in a backup definition, avoid adding many incremental backups between full backups. The DLM process must search through each backup set to check dependencies; therefore, the more incrementals there are, the longer the DLM process takes.
To monitor the backup sets that DLM deletes, you can view the Backup Set Retention category in the audit log. You can also run the audit log report to view the backup sets that DLM deletes.
Warning:
DLM deletes all expired backup sets that are created by a one-time backup job. DLM does not keep the last backup set after the retention date expires if the backup set is from a one-time backup.
