rsync is often used to back up systems, with options such as:

-a --archive

recurse and preserve usual attributes: symlinks, devices and special files, user and groups ownership, permissions and times;

-H --hard-links

detect and preserve hard links;

-A --acls

preserve ACLs, if you use them;

-X --xattrs

preserve extended attributes, if you use them.

In addition to these common options, rsync has plenty others, so everyone has his own recipe, but I would like to share two useful options I discovered.
