We've been given a SP2010 backup (.bak) file to restore. At this time I don't know if it contains a site collection or a site or a farm, or how it was generated, and have no way to find out (just don't ask...).
Using PowerShell, I tried
Restore-SPSite -path foo.bak -identity http://example.com -force
but I'm getting the following error:
Restore-SPSite : Your backup is from a different version of Microsoft SharePoint Foundation and cannot be restored to a server running the current version. The backup file should be restored to a server with version '18.104.22.16805' or later.
My PowerShell reports that I am at version
14.0.6029.1000, which, if I'm correct is 2010 SP1.
I tried looking around (here) but I just can't find out what this weird version number corresponds to. Is there any way I can find out what SP version does this correspond to?
Additionally, I have no access to the server where the backup is generated, so I can't just do something there and regenerate the backup.
Any help appreciated!
