This is using Symantec Backup Exec 2010 r3, on Windows 2008 server. My management wants to have a comprehensive media set backup. For example, I am using one cartridge (Media) for weekly backup for 3rd, 4th and 5th Friday. I want to keep these 3 copies for one month. After one month, this media should be wipe off and re-use from the fresh again for another month. How should I set the settings? in Media set? in Job setup? I shouldn't do the formatting manually.
