i have 2 SQL servers (Development & Production) both have the same scheduled backup job (contains 35 databases). However, on the development server after the job finish i find that there are 2 databases failed to backup and the following error message is there:

Executed as user: NT AUTHORITY\SYSTEM. Write on ‘DBFLog’ failed, status = 112. See the SQL Server error log for more details. [SQL STATE 42000] (Error 3202) BACKUP LOG is terminating abnormally. [SQL STATE 42000] (Error 3013). The step failed.

i do the backup to a backup device whiche i created on the same server. The server has enough space, and when i do the job manually it works fine.

any ideas...

Thankx

Check whether free space available on the development server for these 2 databases, as the restore would calculate the total size of database to replace.

Also check what are the contents on that backup file:

RESTORE HEADERONLY

In case if you have mutliple backups for those databases thenr efer to http://www.sqlskills.com/blogs/paul/2007/10/10/SearchEngineQA7RestoringFromABackupFileContainingMultipleDatabaseBackups.aspx link.
