When you install Backup Exec, a default media set named Keep Data for 4 Weeks is created. All of the media that you use for the backup jobs that you create are automatically associated with the media set Keep Data for 4 Weeks. The backup data is protected from overwrite for four weeks. The media can be appended to for six days.
You can change the media set by doing one of the following:
-
Create new media sets that have the append and overwrite protection periods set to the time intervals that accommodate your data retention strategy. Then, specify the media set that is most appropriate when you create a backup job. For example, you can create a media set that keeps data for 60 days, and a media set that keeps data for 90 days.
-
Select the media set Keep Data Infinitely – Do Not Allow Overwrite . The risk that is associated with the media set Keep Data Infinitely – Do Not Allow Overwrite is that you can use all of your scratch media. You must continually add new media to Backup Exec.
