Using the -L flag to create a snapshot of the live running file system. Does this mean that a complete copy of the file system is written to .snap directory? So if the running file system is more than 50% full there will not be enough free space available to hold the duplicate image? Can dump recognize this situation and issue an error message? Is this the limiting factor that forces a user to use (single user mode) for running dump? 2. What is the worse that will happen if dump is run on live file system with out the -L flag? Can dump recognize this situation and issue an error message? 3. Can dump be told to only dump a particular directory tree? IE /var/log or /usr/port?
