I’ve been building an open-source backup CLI in Go: https://github.com/Cloudstic/cli

Features:

  - encrypted backups
  - content-addressed deduplication
  - local / S3 / B2 / SFTP storage
  - local / Google Drive / OneDrive / SFTP sources
  - restore to ZIP or directory

One thing I wanted to get right was portable drives. If the same external SSD moves between machines, the tool uses its GPT partition UUID to keep the backup history tied to the drive itself, instead of treating every new mount path as a different source.
