sync to external drive

[Xen]

Thanks for the replies.  What I am looking for is to back up some data 
files (images of my artwork- they are synced with Dropbox but I also 
want a local copy).  So what I would like is each time I make a change 
on my hard drive the change would be reflected on the backup medium (I 
want to use the sd card).

I am under the impression that a backup tool would not remove a file 
from a back up device even if it is removed from the hard drive so I 
used the term 'sync.'  Am I correct in this?  Cloud servers sync but 
backup tools do not?

thanks

It's not by default automatic but you can easily set up a job for it 
(say every hour)

However it will do what you ask here.
