Yesterday, Veeam released Veeam Backup and Replication 7, which contains some significant improvements such as backup to tape, parallel backups (simultaneous backups with the same job), SureBackup for replicas, and more. The full list can be viewed either at http://go.veeam.com/v7 orhttp://www.veeam.com/vm-backup-recovery-replication-software.html?ad=men...
This article provides a step by step guide for an upgrade from Veeam 6.5 to Veeam 7.
EDIT : I would like to add a Powershell script to change all compression levels on existing jobs to "optimal" :
Get-VBRJob|Set-VBRJobAdvancedStorageOptions -CompressionLevel 5
