Help with SCSI Tape backup...

[backroger]

Hi...

Can I do a compress backup of my files directly to a tape?

example..

Backup

#tar cvzfb /dev/st0 20 /home/user1

Restore

#tar xvzfb /dev/st0 20 /home/user11

Is this possible? or just ordinary "#tar xvfb" parameters?

Thanks in advance.

It'll make any hardware compression that the device gets moot but it'll work fine. It's a bit more dangerous because if one block on the tape has problems you lose the whole thing where with straight tar I think you'll just lose the file that block was in.

There's nothing about compression that should be breaking tapes. Why don't you try it and find out?

Thanks guys...I just tried it seems to work but Nothinman has a point about bad block in the tapes.

Again thanks for enlighten me.
