tudom, hogy az igazság összetettebb, de ha laikusoknak kell egy mondatban megfogalmaznom, akkor A RAID NEM BACKUP.

Blogging service JournalSpace has been completely wiped out after the drives that housed their entire database were overwritten.

The problem was that their backups weren't actually backups at all. The servers were set up with a mirrored RAID system so that if the primary drive should fail the secondary drive would be used to recover the primary. This alone is risky business, as it only protects you from the failure of one drive. In the case of JournalSpace, the drive didn't fail but instead the data was overwritten/erased on one drive leading the other drive to follow suite and clear itself. A data recovery team was unable to retrieve the database.

So where does that leave you, assuming you didn't lose your blog in the data-meltdown? Hopefully taking a hard look at your backup plan and making sure that there aren't the kind of holes in it that were in the JournalSpace backup plan.
