How to fix Netvault Backup Failed on running backup Differential and Full Backup?

Hello Quest Community,

Good Day. Newbie here. Its been a month of searching solution to fix this error. We are using dell Ultrium tape drive and the netvault has no problem for detecting the tape drive. I also create new selection set for fullback up and differential backup but still got the same error. I would like to know if you encounter same error as mine. Please see the logs below for the error reference.

Your kind attention with this matter is highly appreciated. Thank you. 

  • Hello

    The logs are saying that you haven't run a full backup for the selection set you choose to do an incremental backup. Create a backup job, select the same selection set as this job and in plugin options set select the full option and run it, after that run successfully this job 157 will run ok.
