From BOL:
Log shipping has the following requirements:
SQL Server 2005 Standard, SQL Server 2005 Workgroup, SQL Server 2005 Enterprise Edition, or a later version, must be installed on all server instances involved in log shipping.
The servers involved in log shipping should have the same case-sensitivity settings.
The databases in a log shipping configuration must use the full recovery model or bulk-logged recovery model.
