cd /Users/username

cp -rp /Users/username/Sites /Volumes/drive/username

# -r = recurcive
# p = Cause cp to preserve the following attributes of each source file in the copy:
# modification time, access time, file flags, file mode, user ID, and group ID,
# as allowed by permissions.  Access Control Lists (ACLs) and Extended Attributes
# (EAs), including resource forks, will also be preserved.
