Missing Jobs on tape

Hi. 

I have 5 servers that backup to tape nightly, each on their own job. SRV1 thru SRV5 backup to TAPE01 thru TAPE05. I have a long history of the job for SRV4 backing up sucesfully but I need to restore a single file and when I restore, that server is not in the list of options. I see SRV1, 2, 3, 5 but not 4. I have gone through all my tapes and its the same. Re-catalogued them and nothing. I have gone back in the jobs to verify that it is writing data and there are some 350 files and 50gb of data. 

Not sure what other options i have here.

Thanks
