Can't get granular file .bak or .cmp to restore. “Unable to read cabinet info”

Question

I made a granular backup of my site collection into .bak. and now I'm trying to import said file by using

Import-SPWeb -identity http:testserver/sites/test -path \\sharedstore\backup.bak

I have the site I'm importing to already created at http:/testserver/sites/test

When I did this I got this error

[5/12/2014 8:25:33 AM] Start Time: 5/12/2014 8:25:33 AM. [5/12/2014 8:25:33 AM] Progress: Initializing Import.

When I try to use the -Force command I get the same error.

I also attempted this with the .cmp file getting the same results as above. The error mention not being able to read cabinet info.

Could someone tell me what I'm doing wrong or how to get the restore to work?

from SharePoint Granular backup(Perform a site collection backup) you are getting the backup of site collection( which is Backup-spsite) not the export.that's why you are getting the error when running the import file. Please run the below command( make the changes according to your environment).

Restore-SPSite http://server_name/sites/site_name -Path C:\Backup\site_name.bak
