Bill, thanks for the info. My system should be able to fit on the tape. Does dump compress the data automatically, or should my tape drive do that? Are SCSI tape drives usually at /dev/st0? /dev/st0 isn't found on my system. Anywhere else a tape drive will normally show up, or have I discovered that FreeBSD is not recognizing my tape drive?
