Bash script to backup data to google drive

Question

I want to create a bash script that will log into my google drive account and backup my main folder. I've done a bit of research and I know we need some sort of OAuth for using the Google Drive API but I'm still fairly new so I thought I can get some solid guidance from the stack community.

Solution

I guess you don't need to re-invent the wheel, use gdrive and you're good to go

SETUP:

wget -O drive "https://drive.google.com/uc?id=0B3X9GlR6EmbnMHBMVWtKaEZXdDg"  
mv drive /usr/sbin/drive  
chmod 755 /usr/sbin/drive 

Now, simply run drive to start the authentication process. You'll get a link like this to paste and browse to in to your web browser:

Go to the following link in your browser:  
https://accounts.google.com/o/oauth2/auth?client_id=123456789123-7n0vf5akeru7on6o2fjinrecpdoe99eg.apps.googleusercontent.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&response_type=code&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&state=state 

Authenticate and provide permission for the application to access your Google Drive, and then you'll be provided a verification code to copy and paste back in to your shell:

Enter verification code: 4/9gKYAFAJ326XIP6JJHAEhs342t35LPiA5QGW0935GHWHy9

USAGE:

drive upload --file "/some/path/somefile.ext"

SRC:

Backing up a Directory to Google Drive on CentOS 7

NOTE:

If you really want to build a bash script take a look at this gist , i.e.:

• automatically gleans MIME type from file
• uploads multiple files
• removes directory prefix from filename
• works with filenames with spaces
• uses dotfile for configuration and token
• interactively configuring
• uploads to target folder if last argument looks like a folder id
• quieter output
• uses longer command line flags for readability
• throttle by adding curl_args="--limit-rate 500K" to $HOME/.gdrive.conf

it should be drive about on first launch, to set the key github.com/prasmussen/gdrive#other . Also, i think the command has changed to gdrive, althought drive still works

[reducing activity]

gdrive is not maintained since September 2017

[Pedro Lobito]

And that's a reason to downvote? The answer is from 2015.

As of September 2019 Gdrive is still working very well. Google didnt change its API, so, Gdrive keeps doing its job. Since it's a very simple and bare tool (Gdrive's command line options are not what you would call "friendly") it seems to me that it doesnt requires "maitenance". Maybe it could be "enhanced", but no "maintained".

This is not working , it says App is disabled by google
