Re: [Bacula-users] How to read a writeprotected Tape ?

[Alejandro Alfonso]

And maybe.... 1) dd if=/dev/st0 of=/tmp/tape.dump (where st0 its the *old-ro* device) 2) dd if=/tmp/tape.dump of=/dev/st0 (where st0 its the *new-rw* device) i know nothing about DLT VS160 but maybe it can help you! Best regards Marc Brueckner escribió: Hi there, I am running Bacula in a productive environment for almost two year now and I am totally happy with it. Now I have a little problem an perhaps one of you can help me. (For now this is a hypothetical question.) I need to restore a backup from a write protected tape. Bacula won't mount a write protected tape. bextract or bscan neither. "So switch off the write protect of your tape !" some one would say. The answer is " I can't" because the hardware protects the tape from being written. The tape was written by a DLT VS80 Streamer, now I ve upgraded to a DLT VS160. If I insert a VS80 written tape its automaticly read-only. So if my VS80 streamer dies on day I have no chance to read the tapes by Bacula. I already tryed to dd if=/dev/st0 of=/tmp/tape.dump and tryed to bextract from the filedevice. btape then is able to read the label but bextract terminates with errors. Backup:/etc/bacula # bextract /tmp/ISLBHV_Woche_0 /restore bextract: butil.c:151 Using device: /tmp for reading. bextract: Ready to read from volume "ISLBHV_Woche_0" on device /tmp. bextract: bextract Error: block.c:248 Expected block-id BB01 or BB02, got . Buffer discarded. bextract: bextract Error: block.c:248 Expected block-id BB01 or BB02, got . Buffer discarded. bextract: bextract Error: Read error on Record Header /tmp: Success 0 files restored. I would be happy to have a solution because if my VS80 dies I will need it.
