  • GmailSync v0.2: Support for subdirectories and files > 10 MB

    If you don't know about GmailSync, please read this post first.


    What's New:

    a) Files > 10 MB:
    GMailSync now support files > 10 MB. It splits these files into chunks of specified size and then upload them individually. The file chunks can be later merged by running GmailSync with the argument "merge" from the command line or simply running the "GSyncMerge.bat" file provided with the download.

    Once you run the "GSyncMerge.bat" file, you'll get a dialog box asking to select any file piece. Once you select any part and click Open, GmailSync will generate the complete file by joining all the parts of a particular file. Note that you don't need to select all the files you need to merge. Just select any file.

     

     

    b) Including Sub-directories:

    The application now automatically traverses the subdirectories to include in the backup.

    Configuration File:

    There are few new properties added to the configuration file. If you are upgrading from the previous version then you may need to copy only these properties to keep your old settings.

    <!-- Changes for Version 0.2 . If you are urgrading then only
     copy the following configuration settings to preserve your old
     settings -->
     
        <!-- Set this to true if you would like to include sub directories -->
     <add key="ScanSubDirectories" value="true"/>
     
     <!-- Splits the file into following size if greater than 10 MB -->
        <add key="SplitFileSize" value="5"/>  <!-- In MB -->
     
     <!-- Include the directory information into Email subject to distinguish between
     same name files in different directories -->
        <add key="FullDirectoryPathInSubject" value="true"/>
       
        <!-- Allows you to run multiple instances for different directories.
     If you set this, then you wont be able to preserve your
        settings if you move the directory. -->
        <add key="AllowMultipleInstances" value="true"/>
       
     <!-- End of Changes for Version 0.2 -->

  • GmailSync - Free automated backup solution using Gmail

    Source Code for GmailSync is now available from CodePlex Gmailsync

    Update ** Now with support for sub-directories and uploading files > 10 MB. See What's New.

    What is GmailSync?
    In short, GmailSync is "Blat" for "Gmail". Blat (http://www.blat.net/) is a win32 command line smtp client.
    GmailSync is an automated backup tool to synchronize files on your computer to your gmail online storage. By using this, you can theoretically use almost unlimited amount of free space available on your gmail account.

    Just imagine:
    2.7 Gb * 99 (invites) = 267.3 Gb.

    This tool is inspired by the article written on LifeHacker.
    http://www.lifehacker.com/software/email/geek-to-live-automatically-email-yourself-file-backups-168156.php

    How It Works?
    GmailSync is little more than a simple email client. It uses another third party (free) program called Stunnel http://www.stunnel.org/ to wrap SMTP packets in SSL because Gmail SMTP server uses secure connections. For some reason, I am unable to get the EnableSSL property on SmtpClient to work. Stunnel is bundled with the download therefore you don't need to install or setup another other component before running GmailSync. GmailSync keeps track of the backed up files and only does differential backup the second time you run it.

    Setting up GmailSync:
    Setting up GmailSync is really really easy.

    1) Download: Get GmailSync and extract it in any directory. This is developed with .NET Framework 2.0 therefore you may need to download the 2.0 runtime.
    http://www.microsoft.com/downloads/details.aspx?FamilyID=0856eacb-4362-4b0d-8edd-aab15c5e04f5&displaylang=en

    2) Installation: After extracting the contents from the zip file, just run the Install_Setup.bat file to register the stunnel service and start running it. It'll only take a second or two and then you'll see a little black computer in your taskbar tray.

    3) Configure & Run: After installation, the only thing required is to configure the application. The common configuration parameters are source directory, Gmail username, Password.
    The configuration settings are saved in the application configuration file, i.e. GSyncConsole.exe.config . Just open this file in notepad and there you can see all the configuration parameters and their default values.

    -- Configuration File: GSyncConsole.exe.config
    <?xml version="1.0" encoding="utf-8" ?>
    <configuration>

      <appSettings>
     <!-- The source directory for the backup -->
        <add key="SourceDirectory" value="C:\Data"/>
       
     <!-- Gmail dont' accept some extensions such as .exe or .chm. This parameter
      is used to identify such extensions and then use the ValidExtension property
      to rename the file before sending it to Gmail -->
     <add key="InvalidExtention" value=".exe|.chm"/>
       
     <!-- See the comments on InvalidExtension property -->
     <add key="ValidExtension" value=".pdf"/>
       
     <!-- GmailSync will automatically move the file to this directory after sending
      it to Gmail. If you don't specify this directory then the file remains in
      its original directory -->
     <add key="DestinationDirectory" value=""/>
       
     <!-- Used in the Subject of the email. It can be helpful in setting up a filter
      on Gmail -->
     <add key="EmailFilter" value="[backup]"/>
       
     <!-- The sender of the email message -->
     <add key="EmailFrom" value="yourgmailaddress@googlemail.com"/>
       
     <!-- The receiver of the email message -->
     <add key="EmailTo" value="yourgmailaddress@googlemail.com"/>
     
        <!-- Smtp Server: Leave it as it is as we are using Stunnel as the SMTP gateway -->
     <add key="SmtpServer" value="127.0.0.1"/>
       
     <!-- Smtp Port: Leave it as 465 -->
     <add key="SmtpPort" value="465"/>
       
     <!-- The username to authenticate with Gmail smtp server.
      For most cases, it is same as EmailFrom address -->
     <add key="SmtpUser" value="yourgmailaddress@googlemail.com"/>
       
     <!-- The password for the SmtpUser -->
     <add key="SmtpPass" value="yourgmailpassword"/>

     <!-- Ignore the following fields -->
     <add key="CheckAndRunStunnelOnStartUp" value="true"/>
      <add key="StunnelServiceName" value="stunnel"/>

    <!-- Changes for Version 0.2 . If you are urgrading then only
     copy the following configuration settings to preserve your old
     settings -->
     
        <!-- Set this to true if you would like to include sub directories -->
     <add key="ScanSubDirectories" value="true"/>
     
     <!-- Splits the file into following size if greater than 10 MB -->
        <add key="SplitFileSize" value="5"/>  <!-- In MB -->
     
     <!-- Include the directory information into Email subject to distinguish between
     same name files in different directories -->
        <add key="FullDirectoryPathInSubject" value="true"/>
       
        <!-- Allows you to run multiple instances for different directories.
     If you set this, then you wont be able to preserve your
        settings if you move the directory. -->
        <add key="AllowMultipleInstances" value="true"/>
       
     <!-- End of Changes for Version 0.2 -->
     

      </appSettings>
     
    </configuration>

    Scheduling GmailSync for regular backups:
    Currently there is no scheduling capability built into GmailSync therefore you may need to use Windows Task Scheduler to automate regular backups. The following script registers a task to run everyday at 1:00 am. You may want to change this file to run on any other time.

    schtasks /create /tn "GmailSync" /tr "GSyncConsole.exe" /sc DAILY /st 01:00:00

    Vista update for "GmailSync - Free automated backup solution using Gmail" by: marc1990

    The problem with vista is that it has to install service as administrator. And by run the script as administrator: he wil start in a other dir(C:\windows\system32).
    The solve is simple:
    1. You wil need administrator permissen
    2. Then you have to edit Install_Setup.bat.
    cd stunnel -> cd C:\autobackup\stunnel
    3. Run the script with administrator permission
