dump(8) is able to make a snapshot behind teh scenes, and use that snapshot as
a source for dump:

    -L      This option is to notify dump that it is dumping a live file sys
             tem.  To obtain a consistent dump image, dump takes a snapshot of
             the file system in the .snap directory in the root of the file
             system being dumped and then does a dump of the snapshot.
