What I'm trying to do is: 1) Make regular snapshots on the live filesystems. So long as nothing goes wrong, people can recover individual files from those easily. 2) Back up the live filesystems to one or more backup pools, with all snapshots. This can be restored to the live filesystem if there's a total disaster, or mounted and individual files retrieved if necessary. This does take up more space in the live filesystem; if one eliminated all the old snapshots there, it would be smaller. Since the big things in this environment tend to stick around once they appear, I don't mind this too much. To accomplish 2, I'm trying to use zfs send/receive. I'm not going to archive the stream, just use it to create / update the backup filesystem. So far, I'm running into frequent problems. I can't get incrementals to work, and the last time I made a full backup, I couldn't export the pool afterwards. I had a previous system using rsync working fine, but that didn't handle ZFS ACLs properly, and when I went from Samba to cifs, that became an issue. -- 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
