Here are a few more nuances for those who care. As Ryan says, Jobs that were never properly terminated can for the most part be considered gone. There are, however, a few exceptions. If you were not using data or attribute spooling, you can recover the individual files by selecting the job in "restore" by jobid, and then browse the directory tree. If you had data spooling turned on and nothing was written to tape, it is obviously gone -- there is currently no way to recover the data from the spool directory. If something was written to tape, but no attributes were written in the catalog (they are normally despooled at the end of the job), then if you may be able to recover the files by bscanning the job from the tape. Finally, if the job wrote everything to tape and despooled the attributes but was for some other reason marked failed in the database, it may still be possible to recover the job -- read the end of the Restore chapter of the manual. Bottom line: I know the details of jobs quite well -- how they are written, how they can be recovered, ..., and I wouldn't even think about trying to recover a failed job unless it were the only source of data I had (i.e. everything else is wiped out). In that case (the failed job was the only source of the data), I would also conclude that my backup scheme was seriously flawed and restructure it appropriately ... > > Really, no big deal, since presumably you're making a backup of existing > data.
