I'm a bit unhappy with the User Guide regarding to the tape topics. So I contacted the support whose forwarded me to an Inside System Engineer. The ISE sent links to the User Guide.
Now you're the last best hope.
Does anyone have more information of Veeam and Tape together?
Or knows the config steps to the following specific scenarios?
Scenario 1:
- daily reversed incremental job
- daily copy job with 4 weekly GFS fulls
- weekly tape job of the daily copy job to the weekly media pool => 1 full backup on tape
- monthly tape job of the daily copy job to the monthly media pool => 1 full backup on tape
- no increntals to tape
If I configure that the monthly tape includes all fulls since the last monthly run.

Scenario 2:
- forward incremental job with synthetic full
- weekly tape job of the daily backup job to the full media pool => 1 full backup on tape
- daily tape job of the daily backup job to the incremental media pool => 5 incrementals on tape
If I configure that the tape contains sometimes multiple full backups. Additional the console shows that on the tape are a lot of incrementals (more than a month). But this is not possible because this would exceed the tape size.
Many thanks in advance,
Phil
