Full restore with Sharepoint Foundation

Hello,

I´ve restored a full backup but I get some errors. In the log file, at the end of the restore, I get this message:

PS C:\Users\sharepoint> Import-SPWeb -Identity http://develop_machine -Path C:\intranet.cmp -IncludeUserSecurity

Archivo de registro generado:         C:\intranet.cmp.import.log

Import-SPWeb : En línea: 1 Carácter: 13 + Import-SPWeb <<<<  -Identity http://develop_machine -Path C:\intranet.cmp -IncludeUserSecurity     + CategoryInfo          : InvalidData: (Microsoft.Share…CmdletImportWeb:   SPCmdletImportWeb) [Import-SPWeb], SPException     + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletImportWe   b

PS C:\Users\sharepoint> PS C:\Users\sharepoint>

I use this command for the backup:

Export-SPWeb -identity http://production_server -Path C:\intranet.cmp -IncludeUserSecurity

Regards,

María
