  3. Cause:
    4. The message suggests that the ServosityOBS server detected a size difference between the file size received and the file size that it was expecting. Some possible causes of this issue can be network instability, packet drop, etc.
  4. Resolution:
    5. If the issue only occurs occasionally, you can safely ignore the error.

    In the cases where the network between the ServosityOBS server and the Servosity Proclient remain unstable, you can try decreasing the transfer block size. You can do so by logging into yourServosity Pro console, select [Setting], and modify [Transfer Block Size].

    In the cases where the ServosityOBS server is installed on a Windows 2000 or XP machine. If the file(s) in concern exceeded 4 GB, then the problem is actually related to limitation on the operating system itself. ServosityOBS that run on Windows 2000 or XP will have problem writing file(s) larger than 4 GB.

    Since Windows does not return any write error, it misleaded ServosityOBS to determine that the file write is fine. Thus, the error "File size incorrect" would be returned on every subsequent backups.
