small doubt about rsync

[Tapas Mishra]

I reported a problem while doing an update on one of my servers.
Which is something similar to
https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/705644
I want to restore a backup.
With respect to rsync I have a doubt


If the server A on which I have to restore backup from a USB disk
I do as follows

rsync -avz /usb/disk -e ssh root at IP:/

will it over write all the files on server A with the ones on my USB
(which is what I want also)
or I need to do some thing else.
