Re: [expert] mounting a tape!
Tapes are not random-access devices. Unless there's something new and exciting, you can't NFS mount them (only block devices, not character). You might want to check out rmt (section 8 in your manual). -Ben -- [EMAIL PROTECTED]http://hebb.mit.edu/~ben Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

I glanced at the tar man page, in case it was there, but it does not appear to be there. Tar will handle that. You will need the r commands enabled (rlogin, rsh, etc), and a valid .rhosts Then you can issue: tar -cvf tapehost:/dev/st0 /local/directory To tar up the contents of a local directory onto a remote tape drive.

I doesn't work like Windows software like Direct-CD or equivalent one for tape... You use tar/cpio/dump to backup/ restore you filesytem to/from the tape. If you want to backup different machines with only one tape, export what you need to backup on each machine, and mount every exported filesystems/directories on the server... Or use the machine with the tape as a backup server: it will export some directories. On each machine, mount one from the backup server, copy the data you need to backup to the backup server exported filesystem. Finally, run a backup on the backup server.

Re: [expert] mounting a tape!
REgret to inform you: You cannot export, and mount, a tape device like that. It's a block device, not a character device. There are however utilities out there that will allow you to acces the drive on a remote server. Most any of the better distributed back-up agents will alow this (Amanda comes to mind). If you're desperate, try accessing it via tar: tar -cvf tape_host:/dev/sd0 /home (assuming /dev/sd0 to be the tape device, and /home being the directory to be backed up. If you want to do regular backups, look into the backup agents. You set them up on all the workstations, set up the server, and then just remember to change the tapes on a regular basis.
