Once you have created a backup of your server a copy will be kept on the server with the name 'world.zip' As you create multiple backups these will be numbered 'world1.zip', 'world2.zip' etc. Your hosting provider will have set a maximum number of backups allowed, once this is reached any new backups will overwrite the oldest file. Also when making a backup you are given the option to download these as seen below. It is recommended to take regular backups of your server. Please note that backups only include world files and do not include plugins or configuration files.
