my configuration is a veeam backup and replication 11 that backup an vmware 5.5 infrastructure.
i want to keep one full monthly backup with only 1 retention on a nas.
every months it will start on saturday and rewrite last backup.
I've scheduled a full monthly backup with 1 retention backup on a NAS, the scheduation is configured as above
all vm of esxi are saved,
-backup repository on NAS
-retention policy 1 restore points
-advanced job settings ( incremental without create sybnthetic full) and active full backup on first saturday of month.
Backup started and give successful response, but 0 bytes was saved

Where am i wrong?
