BorgBackup (Borg) is a free, open-source, BSD-licensed deduplicating backup program. It includes compression and authenticated encryption features. It stores files as content-defined chunks to enable space-efficient storage, supports mountable archives, and runs across multiple operating systems.
BackupPC is an open-source, enterprise-grade system that backs up Linux, Windows and macOS PCs and laptops to a server's disk. It includes a web interface for viewing logs and status, initiating and cancelling backups, and browsing and restoring files, plus data deduplication and compression. No client-side software is required. The latest release is 4.4.0, from June 20, 2020.
DMDE is a data recovery tool for disks that can recover directory structure and files in some complex cases. It recovers file types such as photos, videos and documents from HDDs, SSDs, USB drives and memory cards. The free edition recovers up to 4000 files from a chosen directory.
Kopia is an open-source backup and restore tool. It creates encrypted snapshots of designated files and directories and saves them to cloud, network, or local storage. It offers command-line and graphical interfaces and supports compression, deduplication, and error correction.
FolderClone is a synchronization and backup tool for Windows that makes an identical copy of a folder from one drive to another. It runs in the background, periodically checking the source folder and updating the target with new or changed files. It can copy files between computers or replicate data to external drives, NAS or cloud storage such as OneDrive and Google Drive.
ShadowExplorer is a graphical front end for the Windows Volume Shadow Copy Service. It browses point-in-time copies created by Windows 11, 10, 8, 7 and Vista and retrieves versions of files and folders, intended primarily for Home edition users. The site states Shadow Copies are not a replacement for regular backups.
USBImager is a simple GUI application that writes compressed disk images to USB drives and creates backups. It is available for Windows, MacOS and Linux, and its interface is minimalist and multilingual. The application is Open Source under the MIT license.
