Depends where you 'zfs send' those data and what you do on the other side. If you just zfs send <---remote host---> zfs recv and then also make snapshots you have actually very good backup in many aspects much better than using tapes. The only real drawback is management (custom zfs send|recv scripts compared to Legato, Tivolli, ...). -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
