Only initial backup is with full contents, all additional backups are differential to save bandwidth and storage Built-in scheduler ensures backups stay up-to-date automatically. An integrated updater notifies you of new releases. Encrypted backups can be transferred to destinations like FTP, WebDAV, SSH (SFTP), Amazon S3, and more. Flexible backup options: back up folders, specific file types (e.g., documents or images), or use custom filters. Available as a user-friendly application or a command-line tool. Supports backing up open or locked files using Volume Snapshot Service (VSS) on Windows or Logical Volume Manager (LVM) on Linux. Advanced options for filters, deletion rules, transfer settings, bandwidth limits, and more. 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 Backup regularly: Outdated backups are as good as no backups.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. Pull requests for bug fixes or improvements are highly appreciated.
