Step 4. Specify Media Set Options
在本页面
In the GFS media pool, a separate media set is created for each backup cycle: daily, weekly, monthly, quarterly and yearly.
For each media set, you can set the data retention period. The retention period indicates for how long the data is protected from overwriting.
Usually, daily media sets do not contain full backups as daily backups are mostly used to keep day-to-day incremental changes. To complete the backup chain they use the periodic full backup stored in the weekly media set. Due to this, the daily media set creation cannot be enabled unless the weekly media set creation is enabled.
