I used to. Now I think more in terms of getting it from a snapshot maintained online on the original storage server. The overall storage strategy has to include retrieving files lost due to user error over some time period, whether that's months or years. And having to restore an entire 100TB backup to "spare disk" somewhere to get one file is clearly not on. -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
