SQL Server 2008的备份Job突然出现报错，job报错信息如下：Description: Executing the query "BACKUP DATABASE [ascdb_v2_f] TO DISK = N'D:\Progr..." failed with the following error: "A nonrecoverable I/O error occurred on file "D:\Program
Files\Microsoft SQL Server\MSSQL\BACKUP\ascdb_v2_f_backup_2012_03_14_095529_6250000.bak:" 112(failed to retrieve text for this error. Reason: 1815). BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet"
property not set correctly, parameters not set correctly, or connection not established correctly. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 9:55:27 AM Finished: 10:16:45 AM Elapsed:

重建备份仍出现该提示。
备份计划历史现实错误日下：Executing the query "BACKUP DATABASE [ascdb_v2_f] TO DISK = N'D:\\Progr..." failed with the following error: "A nonrecoverable
I/O error occurred on file "D:\\Program Files\\Microsoft SQL Server\\MSSQL\\BACKUP\\ascdb_v2_f_backup_2012_03_13_134336_4218750.bak:" 112(failed to retrieve text for this error. Reason: 1815).
BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established。请问高手该如何解决该问题？是系统问题还是SQL Server软件问题？
