    Make sure SQL server is patched to latest Sp

    You might as well change MTL ( not sure about this) sometimes this message comes due to lack of Virtual memory which can be increased on 32 bit system(only) using -G parameter in startup

  • Hi pulkit,

    According to your description, the actual error could be caused by but not limited to the following issues: Memory issues, Third Party issues, or SQL Server issues and so on. However, as shanky post, if you use an external or third party backup tool like NetBackup, BackupExec, or one of the many other tools available for backing up SQL Server databases without having to write your own backup scripts, and the error occurs. You need to check if there are some issues about your VDI or SQLVDI.DLL. Meanwhile, you also need to troubleshooting Memory Issue or the third tool issue. For more information about troubleshooting the error 995 when backing up database via the third party tool. You can review the following blog.

    In addition, the error may include additional text from the operating system indicating that the disk is full. When performing a backup or restore operation with third-party backup software an additional message may occur indicating that the backup failed.

    Perform the following tasks as appropriate:

     1. Review the underlying system error messages and SQL Server error messages preceding this one to identify the cause of the failure.

     2. Ensure that the backup and restore medium has sufficient space.

     3. Correct any errors raised by third-party backup and restore software.

    There is also detail about backing up database via T-SQL statement /GUI, you can review the following article.
