One copies everything, block by block, while the other just copies files.
One has the advantage of getting every last detail of the drive (if
that's a problem) while the other has the advantage of not needing to
backup 80Gb of data when the drive only has 10Gb on it.
Choose your poison.

To exercise power costs effort and demands courage. That is why so
many fail to assert rights to which they are perfectly entitled -
because a right is a kind of power but they are too lazy or too
cowardly to exercise it. The virtues which cloak these faults are
called patience and forbearance.
Friedrich Nietzsche
