  • Is this Just a single Database or several databases.

    Are any of the databases in read_only mode or something.

    Are all databases in single compatibility mode and none in 70 or 80.

    Are all database accessible.

  • Adding to Mani's questions....

    If backup is failing on only one database, run checkDB on that database. Get in touch with server team and see if disk went offline at that time. When was the last time you had rebooted this server? Check event logs for any disk error messages.

    EnjoY!
  • Database is never backedup till date. Its a DEV server. So planned to perform a backup

    Database compatibility - 80 (all the dbs - simple).

    Disk is fine, as the database files are on the same disk where i tried backing up.

    Database size is 86GB and space available is 51GB. I guess its a space issue.

    But still its showing different error as I/O, am worried if the disk is in danger. Could not able to figure out.

    Any more suggestion.

  • If you are worried about the back Up size, try compressing the back up. Also it is better practice not to put DB or its back up on the OS Drive.

    Also try to back it up to a different location.

  • Change the database compatability level to 100 and make recovery model to full for point in time recovery of database.

    Change the database compatability level to 100 and make recovery model to full for point in time recovery of database.

    Ratheesh, Could you explain how setting the compatibility mode to 100 and recovery model to full help solve the error the OP is getting?

  • Hi Roy,

    So u mean that they need to keep the compatability level in 80 for a sql server 2008 server?

    Is it possible for u to do a point in time recovery in simple recovery model?

  • Hi,

    Just a quick trick to pinpoint such problems, when windows error numbers cannot be resolved:

    System.Data.SqlClient.SqlError: A nonrecoverable I/O error occurred on file "C:\PROCES.bak:" 112(failed to retrieve text for this error. Reason: 1815). (Microsoft.SqlServer.Smo)

    The error number (112) reported by windows is the key here. Use net helpmsg <errornumber> for a more comprehensive output:

    [font="Courier New"]$ net helpmsg 112

    There is not enough space on the disk.[/font]

    No, but changing the compat mode is not going to fix an IO error when doing a backup

    Is it possible for u to do a point in time recovery in simple recovery model?

    It's not, but then no one's trying to do point-in-time recovery here. The backup is failing, and that's not going to be affected by recovery model.
