Best practices include tips and recommendations to help you use Symantec Backup Exec 2010 to manage media 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.
The following best practices are for effective media management:
Create new media sets with append and overwrite protection periods that accommodate your needs. When the overwrite protection periods expire, the media are recyclable and Backup Exec has access to overwritable media.
Overwrite media periodically to keep the media family at a manageable size so that Backup Exec can rebuild the catalog if necessary. You can use a media rotation strategy so that media is periodically overwritten, or select the option Overwrite media when you run a full backup.
Set the maximum size for backup-to-disk files to an appropriate size. If you create small but numerous files, performance may slow since the computer must still process each file. However, if you create large files, file system limitations can cause memory allocation problems or network issues. These issues can be a problem if you store files across a network.
Enable the option Allocate the maximum size for backup-to-disk files to reduce disk fragmentation. To ensure that backup data fills each backup-to-disk file to capacity, increase the append period of the media set that you associate with the backup-to-disk files. The backup data's overwrite protection period may also increase because the overwrite protection period starts at the end of the last append job.
