Usage:

Usage of ./goog:
  - album
        download only from this album (use google album id)
  -folder string
        backup folder (default current working directory)
  -force
        ignore errors, and force working
  -version
        at startup, print the goog version
  -logfile string
        log to this file
  -credentials-file string
        filepath to where the credentials file can be found (default 'credentials.json')
  -token-file string
        filepath to where the token should be stored (default 'token.json')
  -loop
        loops forever (use as daemon)
  -max int
        max items to download (default 2147483647)
  -pagesize int
        number of items to download on per API call (default 50)
  -throttle int
        Time, in seconds, to wait between API calls (default 5)
  -folder-format string
        Time format used for folder paths based on https://golang.org/pkg/time/#Time.Format (default "2016/Janurary")
  -use-file-name
        Use file name when uploaded to Google Photos (default off)
  -include-exif
        Retain EXIF metadata on downloaded images. Location information is not included because Google does not include it. (default off)
  -download-throttle
        Rate in KB/sec, to limit downloading of items (default off)
  -concurrent-downloads
        Number of concurrent item downloads (default 5)
  -loopback-port
        Port number bound on `127.0.0.1` to receive auth code during authentication (default 8080)

On Linux, running the following is a good practice:

$ ./goog -folder archive -logfile gitmoo.log -use-file-name -include-exif -loop -throttle 45 &

This will start the process in background, making an API call every 45 seconds, looping forever on all items and saving them to {pwd}/archive. All images will be downloaded with a filename and metadata as close to original as Google offers through the api.

Logfile will be saved as gitmoo.log.

Naming

Files are created as follows:

[folder][year][month][day]_[hash].json and .jpg. The json file holds the metadata from google-photos.

Building:

To build you may need to specify that module download mode is using a vendor folder. Failure to do this will mean that modified vendor files will not be used.

go build -mod vendor

Testing:

go test -mod vendor ./...

Docker (Linux only)

You can run goog in Docker. At the moment you have to build the image yourself. After cloning the repo run:

$ docker build -t dvgamerr/go-goog:latest .

Now run gitmoo-goo in Docker:

$ docker run -v $(pwd):/app --user=$(id -u):$(id -g) dvgamerr/go-goog:latest

Replace $(pwd) with the location of your storage directory on your computer. Within the storage directory goog expects the credentials.json and will place all the downloaded files.

The part --user=$(id -u):$(id -g) ensures that the downloaded files are owned by the user launching the container.

Configuring additional settings is possible by adding command arguments like so:

$ docker run -v $(pwd):/app --user=$(id -u):$(id -g) dvgamerr/go-goog:latest -loop -throttle 45
