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.
