CloudWays - bash script to download local backups for all applications on a server

# CloudWays - Download local backups for all applications
# =======================================================
# * Local backups must be enabled and available. See https://support.cloudways.com/how-to-download-a-full-backup/
# * Add your machine's SSH key to your server so this script needs no input.
# * Backups will be saved inside a new folder with today's date within your nominated backup directory. (This might not be the date the backup was taken.)
# * Only tested on Digital Ocean VPS so far.

# Configuration
username='YOUR_MASTER_CREDENTIALS_USERNAME'
serverIp='YOUR_SERVER_IP'
backupDir='LOCAL_BACKUP_DIRECTORY_PATH' # Example: '~/CloudWays/Backups'
