When I was trying to backup restore between SharePoint DEV and QA Farms got this error message:
Restore-SPSite : <nativehr>0x80070003</nativehr><nativestack></nativestack>

Clik here to view.
Root Cause:
The source and target SharePoint Farm's build version mismatch!
Solution: Upgrade either the source or destination SharePoint farm and then backup-restore.
Backdoor way:
What if you don't have the option of immediate upgrade and complete this backup restore operation? Here is the backdoor way to skip upgrades and backup-restore SharePoint sites or lists between farms with different versions/build numbers.
One way is: Backup-restore the content database of your SharePoint site collection to the target farm. While mounting your database will be automatically upgraded to target version build schema.
There is an another way: Binary Edit! Just open the backup file in any HEX editor tool, I've used HxD from: http://mh-nexus.de/en/hxd/ , and change the version build number to your target SharePoint farm version.

Try restoring the site collection again, It should work now. Image may be NSFW.
