Automatic-Backup-and-Monitoring-Software

This repository contains the code of a backup and monitoring software that will automatically backup all your data from a selected directory in your PC to External Drive or Google Drive.

This software is written in two Languages. The first one is C and another is Python. C code monitors and takes a backup of data from your computer system to External Drive(if it is attached). Python language monitors and takes a backup of your data from your computer system to Google Drive.

Table of Contents

The headers will be used to reference the location of destination.

The First Part

The first part of this software is written in C language. Here I used inotify instance. It is a Linux Kernel subsystem which monitors changes to the filesystem and report those changes to applications.

I used one main function and that is getNotified(). All the other functions whether these are transfer(), removeFile(), closeInotify(), listDir() are supporting the getNotified() function. So what these functions are doing?

I will be starting from the above code.

  1. transfer() will copy all the data of one directory and transfer them into another directory.
  2. removeFile() will remove a particular file whose location is given.T
  3. closeInotify() will close the inotify instance after monitoring the filesystem.
  4. listDir() will give a list of all the directories so that we can easily count them and use them in getNotified() function.
  5. getNotified() will monitor all the files using all the above functions. This function has mainly three parts.
    • Initialize the inotify instance using inotify_init()
    • Add all the paths and sub paths to watchlist inotify_add_watch()
    • Read all the paths and then use IN_CREATE to monitor the creation of files, IN_MODIFY to monitor the modification of files, IN_DELETE to monitor the deletion of files, IN_MOVED_FROM to monitor the files moved from a path, and at the end IN_MOVED_TO to monitor the files moved to a path.
  6. main() will call the getNotified() function with an actual file path.

The second part

The first part has been covered. Now come to the second part that is to monitor and take backup from computer system to Google Drive. Here I have used three python files. First one is Google.py, second is monitor.py, and third one is main.py.

I also used the PyQt5 for the purpose of making a user interface. PyQt5 has also three files that are selectDrive.ui, selectPath1.ui, and selectPath2.ui. Further three JSON files are also created.

So let's explain what these files are doing?

1. Google.py

  • First of all I took the code from Google Drive for Developers documentation and then modified and used them in a class called MyDrive(). After that, I made some functions.
  • The first one is uploadFiles() that will upload all the present files from the computer system to Google Drive.
  • The second function is uploadFolders() that will upload all the folders from the computer system to Google Drive.
  • The third function is findId() that will find the id of a specific file.
  • The forth function is deleteFile() that will delete a file according to the given file Id.
  • The fifth function is listFolders() that will show all the folders present in a given path.
  • The sixth function is listFiles() that will show all the files present in a given path.
  • The seventh function is main() that will call the MyDrive() class.

2. monitor.py

  • The monitor.py has one class MyHandler() that contains all the events and these events will give message when something is changed in a path.
  • MyHandler() contains three functions. on_created(), on_modified(), on_deleted().
  • on_created() will monitor the creation of files.
  • on_modified() will monitor the modification of files.
  • on_deleted() will monitor the deletion of files.
  • After that, another function is created that monitorFolders(). It will call the the class and use Oberserver() to monitor the path.
  • At the end, I will call the monitorFolders() function to execute the code.

3. main.py

Now come to the last file. It has three classes because the software has three user windows.

  1. The first class is MainWindow() that has four functions.
    • extDriveFunction() will enable the first radio button.
    • cloudFunction() will enable the second radio button.
    • gotoPath1() will enable the next button to go to the external drive window
    • gotoPath2() will enable the next button to go cloud drive window
  2. The second class is selectPath1() that has five functions.
    • browseFile1() will browse the source path.
    • browseFile2() will browse the destination path.
    • backWindow() will enable the back button.
    • operation() will make us notified and it will perform operations to monitor both the paths.
    • closeEvent() will enable the cancel button.
  3. The third class is selectPath2() that has five functions.
    • browseFile1() will browse the source path.
    • browseFile2() and cloudSelected() will will perform operations to monitor both the paths.
    • backWindow() will enable the back button.
    • closeEvent() will enable the cancel button.
