Automatically backup files to your Google Drive account periodically.

Dependencies:

• pip install --upgrade google-api-python-client

Usage:

• Download your client_secrets.json file from the Google Developer Console and keep it alongside the script.
  To do this, perform the following steps:
  • Go to this link and make a new project.
  • In the project settings, turn Drive API on.
  • In the credentials settings, create an OAuth client ID (choose the application type as Other).
  • Click on the Download JSON link and save it as client_secrets.json in your working directory.
• Replace the value of the APPLICATION_NAME variable in the api_boilerplate.py file with the name of the project created in the previous step.
• Add the details regarding the files to be uploaded in the file_list.json file. For new files, keep the fileId empty and parentId as the ID of the Drive directory in which the file has to be inserted.
  The ID of a directory can be found be visiting that directory on Google Drive and looking at the alphanumeric string in the URL.
  
• Modify custom_cmds_pre.sh and custom_cmds_post.sh as per your needs.
• Make sure that the main script is executable - chmod +x ./run.sh.
• For manually running it, just cd into the directory and execute the main script - ./run.sh.
  If you are running it for the first time, you will be asked to authenticate yourself with Google.
• For scheduling it:
  • Modify the contents of crontab.txt as per your needs.
  • Execute crontab -e to open the crontab edit buffer.
  • Copy the contents of crontab.txt in the buffer.

To-Do:

• Add support for uploading contents of a folder recursively without archiving.
• Add support for uploading a file only if it is has been modified. (By comparing hashes)
