• remote-only - move locally created backups to the remote machine. NOTE: Additional configuration KEEP_ONE_COPY_ON_LOCAL allows you to keep one of each backups locally on machine.
• local-remote - rsync backup files between local and remote server

BACKUP_MODE='local-only' ## Available option ( 'local-only' | 'remote-only' | 'local-remote' )

List of directories to backup

You can backup multiple directories by putting them into array. Use :: as a separator between tar file name and directory

  "directory1::/srv/application/www"
  "directory2::/srv/application/storage"
)
