I backup regularly, but just want to double check with the experts that I am doing everything correctly. Would not want to find out the hard way that my copied system image is corrupt because I was doing something wrong.
I am running Windows 7 and nightly backup a system image to an external hard drive using the Windows "Backup and Restore". This would protect me from a drive failure, but unlikely to protect me from malware, since the external drive is always connected.
Weekly, I copy the WindowsImageBackup and MediaID.bin to a second computer and then shut down that computer (second computer is only used for storage) I copy and paste the files using Explorer. The Image folder contains sub folders Backup-date, Catalog, SPPMetadataCashe, and file MediaId. I don't see any sub-folders in these folders. I also copy my raw data to the second computer (just in case).
Every couple of months, I copy my backups from the second computer to a portable hard drive, using Copy and Paste in Explorer. I keep the portable hard drive at a different location.
All this sound proper? Is there any way to validate the integrity of the copied system image, other than actually doing a full restore?
