Duplicati is a free, open-source backup client that securely stores encrypted, incremental, and compressed backups on cloud storage services and remote file servers. It supports:
The beta release will automatically notify you of updates and allows you to upgrade with a single click (or command in the terminal). For even more [bleeding edge access, check the latest releases](https://github.com/duplicati/duplicati/releases) or choose another update channel in the UI or on the commandline.
All releases are GPG-signed with the public key [3DAC703D](https://keys.openpgp.org/search?q=0xC20E90473DAC703D). The latest signature file and ASCII signature file are available on [the Duplicati download page](https://github.com/duplicati/duplicati/releases).

Keep your data safe, store it remotely, and back it up regularly! Many backup solutions fail to meet these essential requirements, but Duplicati excels at all three:
-**Keep your data safe:** Duplicati uses strong encryption to ensure your data remains private. With a secure password, your backup files are safer on a public web server than unencrypted files at home.
-**Store your backup remotely:** Protect your data from local disasters like fires by storing backups on remote servers. Duplicati supports incremental backups, making it efficient to use distant storage destinations.
-**Backup regularly:** Outdated backups are as good as no backups. Duplicati's built-in scheduler ensures your backups are always current. It also uses compression and incremental backups to save storage and bandwidth.
Instructions for setting up your development environment and building Duplicati are available in the [documentation](https://docs.duplicati.com/installation-details/developer). Pull requests for bug fixes or improvements are highly appreciated.
