If it is recognized as, say, /dev/wd1 (for the sake of the argument) then you can dump a complete partition as dump -0uaf /dev/wd1 /dev/wd0s1a The flags are: 0 - make a total as opposed to an incremental backup a - go on until the tape is at the end (unless the backup is copmplete by then) u - log successful dumps to /etc/dumpdates f - dump to device specified (can actually be a file too!) Note that you can only dump partitions with dump, for files and/or directories you use the tar command. And if your drive also exists in a version with an 'r' prepended (a la /dev/rwd1), this is a rewinding device - it rewinds after completion, the device /dev/nrwd1 is a non rewinding device and simply stops where it is when the dump command is finished. In the latter case you can have multiple dumps on one tape easily, in the former you would have to scan forward to end of recording and then dump anew. (For SCSI the command 'mt fsf 1' spins 1 record forward, ie. one dump.) /Micke > > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message ---------------------------------- Michael Josefsson, MSEE mj@isy.liu.se This message was sent by XFMail running on FreeBSD 3.1 ---------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
