FreeBSD device numbers are bigger than the tar formats device number slots. > Are there any other recommended parameters? Yeah - replace "tar" with "dump". Tar was designed to be a tool archiving and sharing data in unixoid file trees. Dump was designed to back up and restore FreeBSD's file systems. The similarity in the requirements for the two tasks ends not far past "copy the data in the files to the media". Even if you don't do that, you might consider adding --compress and changing the file extension to .tar.gz. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
