Append additional backups to a removable disk
I"m using BE 2010 on a Windos 2011 SBS server (Windows 2008). I'm using a USB disk to do periodic Archive backups. The disk has the capacity to hold serveral of these archive backups. The first backup to the disk goes fine but when I try to add an additional backup to the disk I get the error "e0000f16 - The operation failed to acquire the minimum number of drives and media needed.".
I have created a media set named Archive and have the overwrite protection period set to 1 hour and the append period set to 1 hour. The Archive backup job uses that Archive media set.
What do I have to do to make this backup disk appendable?
