I applied the patch and it does get rid of the specific error message but then I get something like amanda@backup:/etc/amanda/TIZ> amverify TIZ No tape changer... Tape device is file:/backup/a... Verify summary to [EMAIL PROTECTED] Defects file is /tmp/amanda/amverify.13907/defects amverify TIZ Tue Sep 10 01:30:30 CEST 2002 Using device file:/backup/a Waiting for device to go ready... and there it will wait, forever. Looking at the amverify script shows that it's not going to work with the file: device without a major rewrite. It uses mt extensively (in the above, it's waiting for an 'mt -f $DEVICE stat' to complete successfully. When $DEVICE is a directory, it will be left waiting :-( Later in amverify, it also waits for an 'mt -f $DEVICE rewind' to complete successfully which again will be a long wait when $DEVICE is a directory. And later, to read the tape label, it's using dd if=$DEVICE which again won't be a whole lot of use when $DEVICE is a directory. To actually read each backup file and pass it to the restore utility to see if it can create a catalog, it uses amrestore on $DEVICE - again, this isn't going to work when $DEVICE is a directory. I have to say that I'm more than a little concerned about this. I'm not so worried that amverify won't work, because I'd see the main use of amverify being to check a tape, and people probably don't want to do this quite so much when using disk (although amverify should work, or perhaps at the moment give an apropriate error message if the file: device is used) BUT I am worried about restoring from my backups. Have any of you who are using the file: device given it a good shakedown testing recovery of files or entire partitions ? Kindest regards, Niall O Broin
