How to use dump?

[Lisandro Grullon]

Hi Daemons,
I have been trying to learn this amazing OS in the last few months, it has a lot of tools which can be useful within my toolbox. I am having some issues using this tool call "Dump", currently located under /sbin/dump, you all know that. ;-). Well, my goal is to do a dump of file system /home which holds all the directories of my users into an external USB drive /dev/da0s1d with mount point is /backup. 
 
I have been searching for some documentation to expand my knowledge on this tool, yet have not been sucesful finding any details of it , I even try the man pages and the handbook and still puzle by how to use this utility. Your input is greatly apreciate. Thank you. Lisandro
