This is the primary difference between a backup system and a disaster recovery system. Systems that are designed primarily for backup can provide you with a way to restore individual files/folders when needed. When you experience a catastrophic or non-catastrophic event you find that they are not a good disaster recovery solution because the data isn’t in a format that can easily be restored to empty/different hardware. Just taking an image of your machine isn’t a solution either because you will find that it can only be restored to EXACTLY same hardware that was running before the failure (something that is virtually impossible if your computer is destroyed). Offsite only backup systems have no chance of restoring to an empty computer (an empty computer doesn’t even have Windows installed) because the computer must be up and running before they can connect to the Internet to even begin downloading a backup.
shadowSafe stores it’s backup copies in a unique format that allows you to utilize our bootable Recovery Environment CD-ROM to restore to almost any computer system. If you are restoring to the same system (due to a hard drive failure, etc.) you just restore all your volumes from your on-site copy. If you are restoring to a different computer (old computer was destroyed or you are upgrading), you just select Hardware Independent Restore (HIR) during the restore process and when the machine it first booted it will discover the new hardware just like an initial installation of Windows.
Reason 7 - Backups aren't actively monitored
