Best practices include tips and recommendations to help you use Symantec Backup Exec 2014/15 to manage tapes effectively. You should also review the best practices for the agents, options, or features that you use for more information. If you use backup jobs for which Granular Recovery Technology (GRT) is enabled, there are additional best practices for media management.
For more information about tape management, see the Backup Exec Administrator's Guide.
The following best practices are for effective tape management:
Be aware of the following consequences of the infinite setting for the overwrite protection period for all tape media:
Create new media sets with the append and overwrite protection periods that accommodate your needs. When the overwrite protection periods expire, the tapes are recyclable and Backup Exec has access to overwritable tapes.
You should overwrite tapes periodically to keep the media family at a manageable size so that Backup Exec can rebuild the catalog if necessary. You can use a tape rotation strategy so that tapes are periodically overwritten, or select the option Overwrite media when you run a full backup.
A media family is a set of tapes that are related because one or more backup jobs span from one tape to another. For example, you back up Resource A to Tape 1. When Tape 1 runs out of space, Backup Exec uses Tape 2 to complete the backup. Tape 1 and Tape 2 are now in the same media family because the backup job started on Tape 1 and finished on Tape 2. If you append more backups to Tape 2 until it runs out of space, then Backup Exec uses Tape 3. Tape 3 is now part of the same media family as Tape 1 and Tape 2. The media family continues to grow as Backup Exec appends backup jobs. A new media family starts when a backup job overwrites the first tape it uses.
