bees is a userspace block-oriented deduplication agent for btrfs filesystems, written in C++. It runs as a daemon that incrementally scans and dedupes new data on live filesystems using a space-efficient persistent hash table.

Use cases

  • deduplicate a large btrfs filesystem to recover free space
  • continuously dedupe new data as it is written without downtime
  • dedupe data across btrfs snapshots and reflinks
  • combine dedupe with btrfs compression
  • run dedupe with minimal RAM using a constant-size hash table
  • throttle dedupe load automatically during maintenance windows

When to choose

  • you run btrfs and want maximum free-space recovery from dedupe, including snapshots
  • you need continuous background dedupe of live data rather than scheduled one-off runs
  • you have large datasets and want a memory-efficient, persistent hash table
  • you want dedupe that coexists with btrfs compression

When to avoid

  • your filesystem is not btrfs (bees is btrfs-only)
  • you need include/exclude filters or per-file dedupe lists
  • you cannot grant root privileges (CAP_SYS_ADMIN)
  • you run an old kernel with known btrfs data-corruption bugs
  • your dataset shrinks often and you need RAM usage to scale down
