If one was to deploy zfs on FreeBSD (after extensive testing) one important issue - for me at least - would be backup to tape. There are links at http://www.freebsd.org/commercial/software.html referring to tape-software. www.ahsay.com and www.cactus.com are both FreeBSD-compatible. Are these backup-solutions able to handle 50-100 GB a day? We have 4 TB partitions and our backup-strategy is only meant to restore entire partitions, not individual files. We are currently using legato on solaris 9 on sparc (very reliable). -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
