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. Disclaimer: I am associated with the Solaris/ZFS vendor, but not authorized to speak for them; my opinions are personal. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
