Yes. In fact, I think that's the only way possible. The end result is ... On my external disk, I have a ZFS filesystem, with snapshots. Each snapshot corresponds to each incremental send|receive. Personally, I like to start with a fresh "full" image once a month, and then do daily incrementals for the rest of the month. There is one drawback: If I have >500G filesystem to backup, and I have 1Tb target media ... Once per month, I have to "zpool destroy" the target media before I can write a new full backup onto it. This leaves a gap where the backup has been destroyed and the new image has yet to be written. To solve this problem, I have more than one external disk, and occasionally rotate them. So there's still another offline backup available, if something were to happen to my system during the moment when the backup was being destroyed once per month. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
