In terms of backing up to an external media or storage rather than doing snapshots. In case the the server spontaneously bursts into flames. Cost would be my main focus, so backing up to a HDD would be preferable. I'm just curious at what others are currently doing to back up huge amounts of data. eg. 2TB and onwards. 1. ZFS -> External HDD (External HDD aren't even big enough to handle greater than 2TB) Taken offsite daily 2. ZFS -> Another ZFS box (Not sure how you take it off site daily) 3. ZFS -> Remote ZFS using RSync (Living in Australia, there are limits on data transfer of a few hundred GB per month, to costs are prohibitive) Regards David N
