Do not use option "Always use a free tape" when backing up multiple machines, a separate free tape is taken for the backup of each machine in the plan.
- You create a centralized backup plan of multiple agents or virtual machines to tape.
- In the backup plan, you set the option "Always use a free tape for each full/differential/incremental".
- A new tape is taken for each machine in plan.
This is expected behaviour in the current product configuration. Backup plan includes backups of multiple machines therefore the condition is met and a free tape is taken after each backup in the plan.
Do not use this option when backing up multiple machines.
