Backup tip
Way back in 1994, Rob Horn gave an excellent tip: randomly restore one file from backup every week. If you have data which you care about (and you do, whether you know it or not), it needs to be backed up. And if it’s being backed up, you need to test that backup system regularly to ensure that you’ve not forgotten something or been bitten somehow. Restoring one random file per week is a good practise to follow.
