A Solution to the Backup Inconvenience
summary
A working backup tool called restic is implemented in Go with a stable, JSON-backed repository and BSD 2‑clause license; it deduplicates using content‑defined chunking (Rabin fingerprinting), encrypts chunks with ChaCha20‑Poly1305, bundles encrypted blobs into pack files with an index, and verifies integrity by matching filenames to content hashes so bit rot can be detected without decrypting. A live USB 3 demo shows about 70 MB/s initial throughput and much higher reuse speeds for known chunks; SFTP and S3 backends exist, FUSE browse/restore works, and planned items include compression, resume, and glacier/asymmetric workflows.
