Best-Effort Extent-Same, a btrfs deduplication agent
bees is a block-oriented userspace deduplication agent designed for large btrfs
filesystems. It is an offline dedupe combined with an incremental data scan
capability to minimize time data spends on disk from write to dedupe.
Hilights:
* Space-efficient hash table and matching algorithms - can use as little as 1
GB hash table per 10 TB unique data (0.1GB/TB)
* Daemon incrementally dedupes new data using btrfs tree search
* Works with btrfs compression - dedupe any combination of compressed and uncompressed files
* Persistent hash table for rapid restart after shutdown
* Whole-filesystem dedupe - including snapshots
* Constant hash table size - no increased RAM usage if data set becomes larger
* Works on live data - no scheduled downtime required
* Automatic self-throttling based on system load
Paths come from the repository package-file index for the observed builds. They describe archive/package associations, not every file that will exist on a running system after maintainer scripts, alternatives, generated state, diversions, or installation choices.
Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
