My vinum volumes allowed me to survive for a long time without backups (bad idea, don't do that), and for the past years have allowed me to survive without having to restore my backups. This through about 5 failing ATA disks and multiple upgrades of the storage space. I'd say it was worth it for me, including reliability. If you need speed, or have the cash, etc, you can go for hardware RAID. But even there I've seen and heard horror stories of incompatible disks, spontaneously lost configurations or even worse, silent data corruption due to a bad disk. I've setup a gvinum mirrored system also, and tried booting it without one of the disks -- you don't need geom_vinum for that so it *is* self sufficient in case of failures. As always, choose the tool that's of best use to you. --Stijn --=20 "An adult is a child who has more ethics and morals, that's all." -- Shigeru Miyamoto --J2SCkAp4GZ/dPZZf Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFB8MUYY3r/tLQmfWcRAgN0AJ9qYrj28X90hF+HMG8+CjES262S2QCeLZwr cm0iQcuz/sphrXv2rkUR3I4= =lgCu -----END PGP SIGNATURE----- --J2SCkAp4GZ/dPZZf--
