tcl2-disk-archive
Redundant data archived from the tcl2 Vast box before local deletion.
Status: placeholder (2026-09-15). Content is being added in verified batches.
Layout (planned)
MANIFEST.jsonl- one JSON line per archived item: local_path, repo, path_in_repo, bytes, sha256, n_files, encrypted, verified_remote, verified_download, deleted_utc.- Tar archives of PNG trees (per-file md5 lists kept in the manifest side files).
*.tar.enc- third-party-derived data, AES-256-CBC (openssl enc -aes-256-cbc -pbkdf2 -salt). The key is NOT in this repo.
Verification protocol
Each item: local sha256 -> upload -> remote LFS sha256/size check (get_paths_info expand=True) -> full streaming download sha256 -> tar -t file count -> manifest line. Local copies are deleted only after all checks pass.
Restore
huggingface-cli download MingzhenL/tcl2-disk-archive <path_in_repo> --repo-type dataset --local-dir <dir>
sha256sum <dir>/<path_in_repo> # compare with MANIFEST.jsonl
tar -xf <file>.tar -C <target>
# encrypted: openssl enc -d -aes-256-cbc -pbkdf2 -pass file:<key> -in x.tar.enc | tar -x -C <target>
