Reader Tomasz sent in a message discussing the demise of JournalSpace. JournalSpace was a relatively small player in the whole blogging boom, but the interesting bit is what caused their demise. Their main database was RAID-1, in other words mirrored to another drive, For reasons that are not entirely clear, both the primary disk and the mirror were overwritten. Speculation is a malicious insider is responsible. Software error is also a possibility.
While this is sad, the important lesson from this is that RAID is not a substitute for a good backup strategy. Your data is your business...If your business is important to you, you should have a comprehensive backup strategy that involves daily backups and most importantly offsite storage of backups.
