I don't think so. The first tar command you show uses the rewind device. It does the first backup, then rewinds the tape. So the second command writes over the first backup. I don't think that's what you want. Rather, use the no rewind device for all the backups save the last. > > No, how to restore data?

The mt command positions the tape correctly, then rewinds. leaving you pointing to the first archive on the tape. But, since the first archive you made was overwritten by the second, the first archive on the tape is the second archive you made. > > Where i'm wrong?
