In their own words
git-annex
git-annex manages large files alongside Git while keeping file contents outside Git itself. Git tracks filenames and metadata, while git-annex stores contents in a distributed store across repository clones. It can synchronize, back up, and archive data online or offline, and it can resume interrupted transfers. The assistant can create a synchronized folder spanning computers, Android devices, removable drives, NAS appliances, and cloud services. Built-in special remotes include S3, Glacier, rclone, rsync, web, WebDAV, and Android adb. Encrypted remotes can protect file contents and use HMAC hashing for filenames, though the project says encryption is mostly not enabled by default. The project describes git-annex as intended for Git users who like command-line work. File size is limited by the filesystem; repositories with hundreds of thousands of files are supported, while larger repositories may slow down due to Git limitations. It is free software, with installation methods listed for Linux distributions, macOS, Android, and Windows. The project explicitly says it is not a backup system, though it can contribute to archival or backup workflows.
