To change general media set properties

1. On the navigation bar, click Media.

2. In the Media selection pane, under Media Sets, select a media set.

3. Under General Tasks on the task pane, click Properties.

4. To change the media set name or overwrite or append periods, click the General tab.

5. Select the appropriate options as follows, and then click OK:

   Name	View or change the media set name. When you rename a media set, any jobs that use that media set will display the new media set name. See Renaming a media set.
   Creation date	Date when the media set was created.
   Overwrite protection period	Enter the length of time, in hours, days, weeks, or years to retain the data on the media before the media can be overwritten (unless the media is erased, formatted, labeled, associated with Scratch Media, or if the media overwrite protection level is set to None). The overwrite protection period is measured from the time of the last write to the media, that is, at the end of the last append or overwrite job. For example, setting the overwrite protection period for seven days and the append period for four days ensures that data will not be overwritten for at least seven days, and that data can be appended to the media for the next four days. The last data appended to this media is retained for seven days. Because of the method Backup Exec uses to compute time, the unit of time that you enter may be converted. For example, if you enter 14 days, the next time you view this property, it may be displayed as two weeks. The default is Infinite - Don't Allow Overwrite, which protects the media from being overwritten for 1,000 years, unless the media is erased, formatted, labeled, associated with Scratch Media, or if the media overwrite protection level is set to None.
   Append period	Enter the length of time, in hours, days, or weeks, that data may be added to the media. Because of the method Backup Exec uses to compute time, the unit of time that you enter may be converted. For example, if you enter 14 days, the next time you view this property, it may be displayed as two weeks. The append period starts when the first backup job is written to this media. The default is Infinite - Allow Append which allows data to be appended until the media capacity is reached.
