We recently upgraded our Netapp filers (760 cluster) to 6.4.1 and were surprised to discover that NBU stopped working for incremental NDMP backups. We are able to run full backups successfully. Tried setting the filer to ndmp ver 3, with the same results. Is anybody running NBU with 6.4.1? I would rather avoid the pain of downgrading. Veritas does not officially support 6.4.1 yet (6.4R1D18 is there most recent supported release), so they have not been much help.

Thanks,

Moshe
