You can configure backup to tape jobs to archive Veeam Agent backups to tape.
Backup to tape jobs treat Veeam Agent backups as usual backup files. The archiving job setup and processing procedures practically do not differ from the regular ones. To learn more about backup to tape jobs, see Veeam Backup & Replication Documentation.
Backup to tape jobs processing Veeam Agent backups have one limitation: you cannot link jobs that process Veeam Agent backups to other jobs. Use other scheduling options instead.
