If you are looking into the Vaulting functionality in Veeam B&R v7 for exported tape media - it would be provided in the future versions of Veeam B&R. For the reporting functionality, may I ask, have you looked into VeeamOne which is the mighty reporting tool that perfectly integrates with Veeam B&R?
In case of CA Arcserve, I hope some other users could share their experience. To my knowledge - it is not integration, you basically schedule a backup job by Veeam, and then point what/when to pick with Arcserve to tape. Restore should look the same - restore from tape to local storage, import backup files to Veeam B&R and then it is possible to run a restore job.
