You can configure your VM to tape job as a secondary destination for the backup job - for that, enable the Configure secondary destination for this job option on the Storage step of the Backup Job Wizard.
When a VM to tape job is run, Veeam Backup & Replication will search and archive restore points from the backups created by the selected backup jobs.
Backup jobs for different platforms (VMware, Hyper-V, vCD) can be combined in a single tape archiving job.
Please note that to add tape as a secondary destination, you should have a backup-to-tape job pre-configured.
