With the cost of tapes, drives, and off-site storage service (unless its stored at the owners home), you could probably co-locate a server with fast internet connectivity, a bundle of local storage, and just ZFS snapshot your relevant pools to that server. I second the recommendation of Amanda from Richard as well though, pretty flexible solution. And it can backup much more than just local ZFS snapshots if that would be a benefit to you as well. -- Brent Jones br...@servuhome.net _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
