This script allows you to easily adjust the upload and download rates for Google Backup & Sync on a scheduled basis.
The script is provided as-is with no warranties. Use at your own risk.
Choose a path for the script to live. A good chocie might be /Users/<USER>/Scripts
Download the script using Terminal application:
curl https://raw.githubusercontent.com/jongracecox/google-backup-and-sync-control/master/google-sync-config.sh > ~/Scripts/google-sync-config.sh
chmod +x ~/Scripts/google-sync-config.shgoogle-sync-config.sh [--upload <rate>] [--download <rate>]
The script can be used in the following ways. For these examples I'm going to assume you are
in the same directory as the downloaded script (e.g. cd ~/Scripts).
To get current settings, run the script with no parameters
> ./google-sync-config.sh
Current settings as at Sat Jul 7 11:03:02 EDT 2018:
>>> Upload rate: 50
<<< Download rate: 500
To set rates use the --upload and --download options. They can be used together or individually.
Rate should be passed as an integer.
./google-sync-config.sh --upload <rate>
./google-sync-config.sh --download <rate>
./google-sync-config.sh --upload <rate> --download <rate>> /google-sync-config.sh --upload 25 --download 150
Current settings as at Sat Jul 7 11:05:33 EDT 2018:

To schedule rate changes you can use crontab on your Mac. If you're comfortable using vi then just use
crontab -e to edit your crontab. If you haven't used vi before then nano may be better, so use
export VISUAL=nano; crontab -e to edit your crontab settings.
Change /path/to/script to the location of your script.
This example will set the following schedule:
| When | What |
|---|---|
| 2am | Set upload to 100 and download to 200 |
| 7am | Set upload to 25 and download to 50 |
Run crontab -e and paste this into your crontab settings.
