Is there anything the checksumming capabilities of ZFS do that cannot be duplicated with an external tool -- perhaps something like a filesystem integrity auditing system? >=20 > I've had a play around with btrfs, which is supposed to be an opensource > equivelent to zfs.

As far as I'm aware, btrfs has not been ported to any BSD Unix systems, either -- so there's a major downside to btrfs (as compared with ZFS). >=20 > Having said all that it really depends on whether you need the extra > features of zfs.

I guess that depends on what you're doing with the data and what kind of external tools you have in place to protect/duplicate it in case of a problem. --=20 Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] --cmJC7u66zC7hs+87 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAkzVutgACgkQ9mn/Pj01uKV7wQCggfS0Rm/UvdS5twPiYpd9GtN2 vjMAnieGVr5dpk+IH4DKoTp3g+Vim21k =sgua -----END PGP SIGNATURE----- --cmJC7u66zC7hs+87--
