You could do that, but the snapshot's creation property is going to be wrong for any snaps that you create that way. Some file properties (such as atime, mtime, and ctime) won't be preserved by the rsync method. If it's important to keep an exact copy of the snapshots, you'll have to receive from each of your old hosts into different datasets, one for each source host. If disk space is a concern, you could enable dedup, which should do well between the last snap of the old server and the first snap of the current server. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
