Thanks for pointing me to that thread. Looks like I'm not the only one in this boat.
Actually, if we go with pure Veeam, we could no longer go with the approach we are doing now. The biggest thing is there is no differential File to Tape backup in Veeam. Our offsite tape safe is not all that big. At present we only need 2 tapes offsite to get the latest data. The Full and the last Differential. If we were to go with Incrementals, we would need the full chain of tapes to go offsite.
