Weekly (or semi-weekly) backup of your flows to Google Drive.
Select your Google account, day(s) of the week, and time of day to backup.
By default will backup to a folder named "Automate Backups" in the root directory of your Google Drive.
Limits number of backups to chosen amount. Will delete the oldest backup if more than set number of backups exist.
Update Jul 6 2021:
Added GUI for setting where to store the backups and how many backups to store.
Fixed backups occurring daily instead of based on selected weekdays.
