Prerequesits

Create an application on Google Drive to get the credentials.json that needs to be sent with each request.

[https://developers.google.com/drive/api/v3/quickstart/nodejs#step_1_turn_on_the](Access Google Api Authorization)

Click Enable the Drive Api button to create an application and download your credentials.

Usage

Currently the following three commands are available (all on the root location):

• Authorization with Google Drive
• Backup (upload) of a file
• Download of a backed up file

If a folder has to be backed up tar or similar compression programs should be used.

Backup a file

I file is uploaded using the backup option. The second argument adds a tag to the backup that is used to retrieve the backup.

gdrive-backup backup testupload.txt testtag -c mycredentials.json

Help:

Usage: backup [options] <path> <name>

Backup a specific folder with a backup name tag.

Options:

	-c, --credentials-path <credentials-path>  set [credentials-path] file path (default: credentials.json)
	-t, --token-path <token>                   set [token] file path (default: token.json)
	-s, --encryption-key <encryption-key>      set [encryption-key] file path used for encryption (default: encryption-key)
	--token-code <code>                        set token code needed to authorize the app
	-h, --help                                 output usage information

Download a file

After a successful backup the file can be downloaded using the provided name tag. If there are multiple files with the same tag, always the latest (newest) file is downloaded.

gdrive-backup download testtag -c mycredentials.json -d testupload.txt

Help:

Usage: download [options] <name>

Download latest backup with given name tag.

Options:

	-d, --dest <file>                          set destination file
	-c, --credentials-path <credentials-path>  set [credentials-path] file path (default: credentials.json)
	-t, --token-path <token>                   set [token] file path (default: token.json)
	--token-code <code>                        set token code needed to authorize the app
	--no-input                                 set flag to not process user input (e.g. to input the authorization token in shell)
	-h, --help                                 output usage information

Storing and retrieving backups with properties

When backup is called the file is identified with the provided name tag. This tag is set as the backup_name property for the uploaded and created backup file on Google Drive to allow finding it within a folder.

The counterpart download searches for the newest backup ordering by addedTime desc and checking the property backup_name. If a directory is provided also the directory id is included. The final search query therefore looks like this:

properties has { key='backup_name' and value='name' } and 'folder_id' in parents
