I have a Backup to Tape job which runs continously, copying full backups to an HP MSL4048 tape library as they re created. I have set the job to "Export current media set once the job finishes" once per week on a Thursday. I thought that this would also trigger creation of a new media set, but instead I get lots of "No media in drive" errors after the media set has been exported. Looking at the media pool in Veeam, all tapes for the media pool are offline. The media pool properties are set to "Do not create, always continue using current media set". If I also set this to create a new media set each week, I end up getting two new media sets per week.
Is this expected behaviour? Can I only do what I want by setting the weekly media set creation via the media pool properties and not exporting the media set in the backup job? What happens if a backup to tape job is running at the time the media pool creates the new backup set?
I would like to add that I think Veeam 7 is a fantastic product. The new tape support is just what we need, barring a few minor issues like that above - but considering it's your first tape support release, I'm happy if I can work around these issues for now.
