Destination overview

This page describes what a "destination" is to Duplicati and lists some of the available providers

Duplicati makes backups of files, called the source, and places the backup data at a destination chosen by the user. To make Duplicati as versatile as possible, each of the destinations are implemented as a "destination" (or "backend"), each with different properties.

Some storage providers support multiple protocols with each their strenghts, and you can generally pick which storage destination provider you like, but if there is a specific implementation for a given storage provider, that is usually the best pick.

Each storage destination has a number of options that can be provided via a URL like format. The options should preferably be provided as part of the URL, but can also be provided via regular commandline options. For instance, the --use-ssl=true flag can also be added to the URL with &use-ssl=true. If both are provided, the URL value is used.
