What's changed

Changes

  • Experimental TUI: Introduced a modular Terminal User Interface for interactive repository management. Includes a dashboard, snapshot creation, restoration, and retention management.
    Experimental: may be removed or replaced in a future release.
  • Bundle command: New bundle command to create and restore standalone .mapache bundle files with full deduplication and encryption.
  • FUSE Bundle Mount: Mount .mapache bundles as read-only filesystems via the mount command.
  • TOML Config File: Added support for a .toml configuration file to centralize repository settings and runtime defaults.
  • Enhanced Retention Rules: Added --host (multiple), --keep-hourly, and --keep-min flags to the forget command for more granular snapshot retention control.
  • Memory-Efficient Restore: Blobs are now written immediately after decoding, reducing peak memory from O(all blobs in segment) to O(1 blob). Cuts restore memory usage without sacrificing parallelism.
  • Robust S3 Backend: Implemented multipart uploads for files >= 128 MiB and recursive listing to avoid hundreds of directory requests during garbage collection.
  • Improved GC Efficiency: Stream snapshots instead of loading all into memory upfront and process repack chunks in parallel with pipelining.
  • Memory-Efficient Verification: Refactored verification to use a streaming approach, capping memory usage for large packs.
  • Enhanced Atomic Locks: Added better metadata and robust stale lock detection with detailed conflict reporting.
  • Hardlink Restoration: Restorer now detects and recreates hardlinks from snapshots, preserving inode sharing and nlink counts on Unix.
  • Access Time Preservation: Added --with-atime flag to snapshot to optionally store and restore file access times. atime is not stored by default to avoid unnecessary metadata growth. On Linux, O_NOATIME is used when reading files to prevent the backup process from modifying access times.
  • Key export: Added key export subcommand to extract a key file from the repository and save it locally.
