I am using a DVD+RW, format it with dvd+rw-format -force /dev/cd0, and then do: dump -0 -b 32 -B 4590208 -f /dev/cd0 / to backup the root filesystem. I do this after going to single user mode. It seems that dump is perhaps not properly closing the file? The DVD drive light remains on, and I get errors from restore: tape read error: Unknown error: 0 dvd+rw-mediainfo /dev/cd0 is more informative: /dev/cd0: unable to open: Device busy I *can* dump to a file on a filesystem, and use growisofs to write this dump file to the DVD. No problems mounting and reading the resulting dump file. Unfortunately, I do not have enough free disk space to do this with my larger file systems. This is with 5.3-RELEASE. Thanks in advance for any suggestions. sdb -- sdb@ssr.com
