Kopia features a robust and adaptable architecture, enabling it to back up a wide range of devices, from small laptops to extensive server systems. As a fast and secure open-source tool for backup and restoration, Kopia efficiently manages filesystem snapshots stored in a remote location. It uploads files and directories to a designated remote storage known as a Repository, while also keeping a historical record of snapshots at various points in time, all governed by user-defined policies. Each snapshot is generated incrementally, ensuring that data already captured in previous snapshots is not re-uploaded to the repository, thus optimizing storage efficiency. In fact, when files are moved or renamed, Kopia adeptly identifies that they contain the same data, eliminating the need for redundant uploads. Furthermore, multiple users or devices can access the same repository, ensuring that shared files are only uploaded once, conserving bandwidth and storage resources. For data restoration, Kopia allows users to mount the Repository's contents as a local disk, facilitating the use of standard file copy tools for either complete or selective restoration of data, making the process user-friendly and efficient. This unique approach to backup and restoration emphasizes both efficiency and ease of use across diverse computing environments.
