When you upgrade Veeam Backup & Replication to V8, you have available the new Forward forever-incremental mode for your backups. This is the default method for all newly created jobs, but the already existing backup jobs are not changed, because we do not want to change the user experience or create issues to I/O profiles, backup windows and such.
This great powershell script will take all your existing forward incremental backup jobs and reconfigure them to use the new forward forever-incremental mode.
