Not safely (at least, you can't safely dump a mounted filesystem). dump
and restore access raw devices directly, and Linux's raw devices are not
cache-coherent with the filesystem: in particular, you can have pieces
of metadata inconsistently visible through the block device which have
actually been completely written to the device, or vice versa. That way
lies madness (at least it does if the filesystem is busy).

Filesystem authors hate dump(8). Use something else if at all possible.
