I expect that, and do "full" rsync backups every night, and a second "full" backup to a different machine every week. dirvish.org, which I maintained for more than a decade. The backup machines and drives are on (separate) medical grade isolation transformers(*), hence protected from most power-line faults, even lightning direct to the pole. Diagnosing a drive failure, then restoring to a new drive from backups, is time consuming, so I would rather spend an extra $200 for a twice-as-reliable drive. But what is reliable, and what is fake? Unfortunately, the extra $200 must be discounted by vendor mendacity. Keith * Note to thieves - the transformers are 200 pounds and bolted high on a concrete wall, behind a lot of heavy steel shelves. A theft will take days. You will pay more to rent the fork lift than you will get for the transformers (which I bought as scrap and repaired). -- Keith Lofstrom kei...@keithl.com
