You need to accomplish a full backup of all files in the /export/home file system to the /dev/rmt/1 remote tape device attached to the workstation mars.
Which command accomplishes this?

A.
ufsdump 0f /dev/rmt/1 /export/home

B.
ufsdump 0f mars:/dev/rmt/1 /export/home

C.
ufsdump 0f /dev/rmt/1 mars:/export/home

D.
ufsdump 0mf mars /dev/rmt/1 /export/home

E.
ufsdump 0f rd=mars:/dev/rmt/1 /export/home

Explanation:

The number 0 is for the dump level (full) and f for file. The syntax of the command is: ufsdump options <device to dump to> <device to backup>. As the device /dev/rmt/1 is located on the machine mars, "mars:" needs to be specified.
