Mackup is a backup and synchronization tool that manages application configuration files across multiple workstations.
The tool solves the problem of manually reconfiguring applications when setting up new machines. It works by tracking pure configuration files for supported applications and storing them in a centralized location, excluding cache, temporary, and locally specific files. Mackup offers two operational modes: copy mode, which duplicates configuration files to a backup storage location, and link mode, which moves configuration files into the backup folder and creates symbolic links to their original locations. Users can back up settings from one machine, then restore or link them on another machine with a single command.
Mackup suits developers and power users who work across multiple workstations and want to maintain consistent application configurations. It supports numerous applications and can store backups in various cloud storage services. The tool works on macOS and Linux. Users should be aware that link mode has known issues on macOS and may not function correctly on that platform. The project provides per-application control, allowing users to back up or restore individual applications rather than only operating on all configured applications at once.
The project maintains active engagement with configuration management across diverse application ecosystems. Development includes ongoing support for new applications and storage backends as users request them. The codebase remains responsive to platform-specific issues, including documented limitations and workarounds for certain operating systems.
