Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I have stumbled over a quite serious problem (for me anyway): With a 3.0-SNAP from around August 1998 I have made a number of backups via 'dump' to my Tandberg SLR5 scsi tape drive. After installing 3.2 the other week I would like to be able to read my old backups - and cannot. I get a 'tape: input/output error' every time I try to restore. I have tried to 'cat /dev/nrsa0'. With tapes I made today I can cat happily but with the old tapes I always get the above error. I have tried to set density with 'mt density QIC-2GB' but never succeeded, and I am quite sure I have not set any density in the past. But used the default for the drive. Back then the device was called /dev/nrst0 and now it is apparently /dev/nrsa0. Making new dumps/restores with nrsa0 goes without any problems at all. What can I do? Is there a revision of dump/restore protocol between 3.0-SNAP and 3.2? Is there ANYTHING I can do to get my data back - even if it entails getting it to file and use vi to extract the files I want? Is this a general problem, i.e. that old dumps don't read with new OS versions? (I hope not). So there you are, any tips are welcome! /Micke BTW. I do not have the dist of 3.0-SNAP as I downloaded it from the net, so I can't reinstall that version:( ---------------------------------- Michael Josefsson, MSEE Linköping University 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-stable" in the body of the message
