While you are restoring a transaction log for a Microsoft SQL Server 2005, a Microsoft SQL Server 2008, or a Microsoft SQL Server 2008 R2 database, you may receive an error that resembles the following in the SQL Server Errorlog file:
Error: 18272, Severity: 16, State: 1.
During restore restart, an I/O error occurred on checkpoint file 'X:\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\CHECK.CKP' (operating system error 1784(The supplied user buffer is not valid for the requested operation.)). The statement is proceeding but cannot be restarted. Ensure that a valid storage location exists for the checkpoint file.
Symptoms
This error has a limited impact and does not prevent a restore operation from succeeding. This error message occurs when a restore is interrupted, and the checkpoint file that is used to restart a restore is not written, or the checkpoint file is not written correctly. If you receive this error, it means that, if for some reason the restore operation is interrupted in the middle of the process, you have to restart it from the beginning of the backup file rather than the checkpoint file.

Workaround
The error message usually occurs when you are restoring from multiple backup files, a process that is sometimes referred to as a "striped restore." To avoid the error, do not specify multiple backup files in your restore operation.
Resolution
The problem is frequently reported by customers who use third-party backup software tools to back up their SQL Server databases. These tools facilitate backup and restore operations across multiple files.
