Most of my department's large UNIX filesystems are NFS mounted from ZFS (not zFS) on Solaris servers. Our daily backups are ZFS snapshots, almost negligible latency, followed by background dumps to tape.
Right. FLASHCOPY of a large volume on our DS8100 can be done in almost an instant. But, copying the volume's data to tape takes hours -- as mentioned previously.
My question is about whether a DFS/SMB ZFS should be backed up at all given its size and the existence of a daily TSM backup of its contents.
