Hi all,

When I perform a full backup of all files in the root (/) file system
to tape device (/dev/rmt/0), I use this command:

# ufsdump 0 /dev/rmt/0 /

However, my friend tells me that I don't need to use "0" because
default backup level of Ufsdump is level 0. So I can use:

# ufsdump /dev/rmt/0 / 

Is he rite?

Thanks.

I just tried

	ufsdump f /dev/null /

and it does a level 9 dump, not a level 0.

Also, the manual page says:

      If no options are  given,  the  default  is  9uf  /dev/rmt/0
      files_to_dump.

That doesn't say explicitly, but it seems like that means the
default for the dump level is 9, even if you do specify other
options.
