Duplicati manages ensuring data integrity and security in backup operations by providing a robust, zero-trust backup solution. Technically, Duplicati is built using C# and runs within the Common Language Runtime (CLR), making it cross-platform compatible with Windows, macOS, and Linux environments. It supports both graphical and command-line interfaces, allowing for flexibility in deployment, including headless systems like servers or NAS devices.
The architecture of Duplicati emphasizes encryption, compression, and incremental backups. It uses standard components such as rdiff and AESCrypt for encryption, ensuring that backups are fully encrypted and can be recovered even if Duplicati itself is not available. The software integrates with a wide range of cloud storage services, including Amazon S3, Google Drive, and Backblaze, as well as protocols like SSH/SFTP, WebDAV, and FTP. This flexibility allows users to choose any storage medium that supports basic commands like GET, PUT, LIST, and DELETE.
Operationally, Duplicati offers real-time monitoring and alerting through a centralized dashboard, enabling users to manage and monitor backups from anywhere. The system supports agent-initiated connections, ensuring secure communication and management. However, it's important to note that while Duplicati is highly scalable, managing large numbers of backups can introduce complexity, particularly in terms of storage costs and retention policies. For example, the free plan limits monitoring retention to one year, while the Pro plan extends this to three years, highlighting the need to balance backup frequency and retention with storage costs.
In terms of specific technical details, Duplicati's use of disk snapshots (via VSS on Windows and LVM on Linux) and remote verification of backup files are notable features that enhance data integrity. The software also supports speed limits and pause functionality, which can be crucial for managing network bandwidth during backup operations. Overall, Duplicati's design prioritizes security, flexibility, and ease of use, making it a robust solution for backup needs across various environments.
