Issue

I have encountered an error in the web export/import routine. The thing is that the feasibility of import seems to depend on the state of the web.

I have several subsequent export packages of the same web and say #2 works fine (I can see it extracting the contents of the package and the result is that the web is imported) and #3 fails (I don’t see the files being extracted and the import fails almost immediately).

PS C:\Windows\system32> Import-SPWeb -IncludeUserSecurity -Path C:\Install\exportweb2.bak -Identity https://test.company.com/sites/home -Force

Log file generated: C:\Install\exportweb2.bak.import.log

PS C:\Windows\system32> Import-SPWeb -IncludeUserSecurity -Path C:\Install\exportweb3.cab -Identity https://test.company.com/sites/home -Force

Log file generated: C:\Install\exportweb3.cab.import.log

The adm_user account is a local administrator on all the machines in the farm except SQL Server and the SPShellAdmin rights have been granted.

There definitely are the Requirements.xml and ExportSettings.xml inside the package, I checked this with my archiver.

I believe this is rather a common trouble to shoot and any help would be appreciated.

Check the size of your export package. There is a default cab size of about 25Mb – this used to be a limit you had to increase with stsadm by setting a parameter. With the PowerShell Export-SPWeb cmdlet it generates multiple files if you hit the limit. You may need to change this limit using the CompressionSize parameter to set the cab size (up to a maximum of 1024Mb).

Example:

Export-SPWeb http://mysite -Path c:\backup\ExportFile -CompressionSize 1000
