# ^every monday at 12:00PM   ^path to backup on google drive         ^stream redirect ^path to backup log

# Basic manual usage
# drive_backup /path/to/directory/or/file

# File names will contains full path and date for uniqueness. 
# Example: i want to backup /var/www/public, file name will be: var_www_public_2017-03-03.tar.gz
# If you need to backup every few hours (for example), just change DATE variable to DATE=$(date '+%Y-%m-%d %H:%M:%S')
