Duplicati

Duplicati is an open-source backup software application for encrypted, incremental, and compressed backups to local and remote storage targets.

• Open-source backup solution for files and folders across desktops and servers
• Encrypted, incremental, and compressed backup workflows with deduplication (data protection / backup)
• Support for multiple back-end storage targets, including local disk, network shares, and common cloud storage services (data management)
• Web-based graphical user interface and command-line tooling for configuration and automation (systems administration)
• Scheduler and retention policy features for recurring backups and backup lifecycle management (IT operations)

More About Duplicati

Duplicati is positioned as an open-source backup software platform (data protection / backup) that enterprises, public-sector institutions, and individual users can deploy to protect files and folders across Windows, macOS, and Linux systems. It focuses on creating encrypted, incremental, and compressed backups that can be stored on a range of back-end targets, including local storage, network file shares, and cloud storage services.

The software is built around a client-based architecture where the Duplicati service runs on each protected machine and manages backup jobs to one or more destinations. It exposes a web-based graphical user interface that is accessed through a browser, which allows administrators to configure backup sets, scheduling, encryption, filters, and retention rules. For scripted or automated use in enterprise environments, Duplicati also provides command-line tooling so jobs can be integrated with Operating System (OS) schedulers or configuration management systems.

Duplicati supports common encryption standards such as Advanced Encryption Standard (AES) for securing backup data before it leaves the source system. It typically combines encryption with compression and block-level deduplication to reduce storage consumption and network transfer. Incremental backup behavior is implemented using block-based approaches, where only changed blocks of files are transmitted after the initial full backup. This design aligns Duplicati with the broader enterprise backup and recovery category, particularly for file-level and workstation/server backups rather than application-aware database backup stacks.

The platform is compatible with multiple storage protocols and services, covering typical enterprise storage options. These include local disks and network paths (such as SMB/CIFS-based file shares) as well as many commercially available cloud object storage and file storage offerings. This allows organizations to route backups to on-premises (on-prem) storage arrays, Network Attached Storage (NAS) devices, or public cloud buckets, depending on policy and regulatory requirements.

From an operational perspective, Duplicati includes built-in scheduling and retention management. Administrators can configure automatic recurring backups at defined intervals and set retention policies that govern how many versions to keep and when to delete older backups. Email reporting and logging help operations teams monitor backup health and troubleshoot failures.

In enterprise or institutional environments, Duplicati is often used for endpoint backup, small server workloads, lab or departmental systems, and environments that favor open-source tooling and flexible storage choices. It resides in marketplace taxonomies under data protection, backup and recovery, and storage management, with emphasis on encrypted, incremental, file-level backups across heterogeneous operating systems and storage destinations.
