How to Validate if my recovered Disk is equal to my Backup

Thread needs solution

I just recovered a disk from a backup, but I had a validation error during recovery.

 

I am migrating from a 256Gb SSD to a 500Gb SSD  so I made a backup of the old SSD, validated the backup, all was fine. I then created a Rescue Media, swapped the SSDs, rebooted the laptop, initiated the recovery process and selected to validate the recently created backup again.

Then the validation failed, saying there was an error at validation, but I could continue the recovery. I decided to continue and recovered the backup to the new SSD.

Now just to be sure all is fine, I want to Validate the Backup on my external drive against the newly recovered SSD, is this possible? Or is the validation only against the backup file itself?

Are there any ways of making this kind of comparison?

Michel, welcome to these public User Forums.

Validation will only work against the actual backup archive .tib file, it cannot verify the contents of the file beyond the point that they remain unchanged from the time the file was created.  It does this by recalculating a series of checksums based on the file data and comparing to the checksums which are embedded within the file itself.

The only method of trying to compare the contents of your backup archive with the contents of your drive after restoring, would be to mount the archive to a drive letter, then run a file comparison or synchronisation utility between the two drive letters.  The downside of this approach is that the restored data may already have many changes, especially if this is a Windows OS drive that you have booted the computer from.

Sorry but that level of detail has never been declared or published by Acronis.
